September is when Cannes stops performing. The red carpets from the May Film Festival are long gone, the August holiday crowds have dispersed back to Paris and Lyon, and what remains is a Mediterranean town of 75,000 residents with warm water, half-empty beaches, and prices that finally make sense. Daytime temperatures sit around 26°C (79°F), warm enough for a full afternoon on the sand without the draining 30°C+ heat that flattens you in July and August.
The Mediterranean Sea reaches its warmest point of the year in September, typically around 23-24°C (73-75°F) after absorbing heat all summer. That difference matters. If you tried swimming in June, you remember the sharp chill at 19-20°C. In September, the water feels almost bathlike. The one disruption to the month's calm is the Cannes Yachting Festival, which takes over the Vieux Port and Port Pierre Canto for 6 days in the second week. It draws roughly 50,000 visitors and fills hotels across the entire Côte d'Azur. Outside that window, the city belongs to locals and a quieter stream of off-peak visitors.
Rainfall does tick upward from summer's near-zero baseline, with about 62mm spread across 6 rainy days. These tend to arrive as short, sharp Mediterranean downpours rather than grey all-day drizzle. You might lose an afternoon to a storm, but the sky usually clears by morning, often leaving the Esterel mountains looking sharper and more red-ochre against the water. The air after one of those September storms has a particular quality, clean and mineral-scented, that regulars on the Côte d'Azur will tell you is their favourite version of the place.
Why visit in September
- Mediterranean Sea at its warmest (23-24°C / 73-75°F), the best month for swimming on the Côte d'Azur without a wetsuit
- Hotel rates drop 30-40% from the July-August peak, with most properties and restaurants still fully open through mid-September
- Crowds thin to roughly half of August levels, meaning shorter waits at Marché Forville and more breathing room on the public beach strips along La Croisette
- Provençal produce hits a September peak with Solliès PDO figs, muscat grapes, and late-season tomatoes at the daily markets in Forville
- Comfortable 26°C daytime temperatures make walking Le Suquet's steep lanes and the coastal paths actually pleasant, rather than the endurance test they become in July
Worth knowing
- Rainfall rises to 62mm over 6 days, with Mediterranean downpours that can arrive fast and cancel a beach afternoon with little warning
- The Cannes Yachting Festival in the second week temporarily pushes hotel prices and port-area crowds back to near-summer levels for 6 days
- Some beach clubs and seasonal restaurants begin closing after mid-September, especially along the western stretches of La Croisette and toward La Bocca
- Daylight hours shorten noticeably, with sunset dropping from roughly 20:00 on September 1 to about 19:15 by September 30
Best for
Think twice if
September eases off from the peak summer heat into a comfortable range that still feels like proper beach weather. Highs hover around 26.2°C (79°F) with lows near 17.8°C (64°F), and 62% humidity that rarely feels oppressive. Rainfall reaches about 62mm over 6 rainy days, mostly as brief afternoon downpours that clear within a few hours. Mornings tend to be sunny and warm. The sea temperature, around 23-24°C (73-75°F), is the warmest you'll find all year. By late September, sunset drops to about 19:15, noticeably earlier than August's 20:45.
Seasonal caution
- September marks the start of the Mediterranean storm season (épisodes méditerranéens). While more common in October, these weather systems can appear in the second half of September and drop 50-100mm of rain in a few hours. The Alpes-Maritimes département issues orange weather alerts (vigilance orange) when these systems approach. Check Météo-France forecasts before island day trips, as ferry services to the Îles de Lérins suspend without notice during heavy weather.

Headline events
Cannes Yachting Festival
Second week of September (Tuesday to Sunday, typically September 9-14)
Europe's largest in-water boat show fills the Vieux Port and Port Pierre Canto with over 600 vessels, from 3-metre dinghies to 50-metre superyachts. Around 50,000 visitors attend over 6 days. The event dominates the city's waterfront, drawing yacht buyers, marine industry professionals, and spectators from across the Mediterranean. It transforms the port quarter's restaurants and bars into something closer to Film Festival intensity.
Best things to do in September
Swimming at the public beaches along La Croisette and Plage du Midi
beachThe Mediterranean hits its yearly temperature peak in September, typically 23-24°C (73-75°F). The public beach strips between the private concessions on La Croisette are narrow but free, while Plage du Midi west of the Vieux Port stretches wider with more space. The water has a clarity in September that the churned-up August surf often lacks.
Sea temperature at its annual maximum, 3-4°C warmer than June. Crowds at roughly half of August levels.Booking tipNo booking needed for public beaches. Arrive before 10:00 to claim a good spot on La Croisette's narrower free strips.
Day trip to Île Sainte-Marguerite
outdoorsThe larger of the two Lérins islands sits a 15-minute ferry ride from the Vieux Port. Fort Royal, where the Man in the Iron Mask was imprisoned in the 1690s, anchors the north side. Eucalyptus and Aleppo pine forests cover the interior with shaded trails. The south-facing coves have some of the clearest swimming water on the Côte d'Azur.
Ferry queues drop from 30+ minutes in August to under 10 in September. Water warm enough for comfortable swimming in the rocky coves. 26°C makes the forest trails pleasant rather than sweltering.Booking tipFerries run roughly every 30 minutes in September, down from every 15 in August. Check the last return time, which is usually around 17:30 in late September.
Exploring Marché Forville during fig and grape season
foodCannes' covered daily market in the Forville quarter sits below Le Suquet's old streets. September brings the year's best produce overlap. Solliès PDO figs, muscat grapes, late-season tomatoes, courgette flowers, and fresh herbs share the stalls. The atmosphere on weekday mornings is noticeably calmer than in summer, with more locals doing their daily shopping.
Solliès figs and muscat grapes both peak in September. The summer tourist crowds have largely gone, so the market feels more like a local food hall than a tourist attraction.Booking tipThe market opens at 7:00 Tuesday through Sunday. Go before 9:00 for the best fig selection. Monday is flea-market day instead of food.
Hiking the coastal path from La Croisette to Pointe de la Croisette
outdoorsThe Sentier du Littoral follows the rocky shoreline east from the Palais des Festivals out to the Pointe de la Croisette headland, about 3km each way. The path passes millionaire villas, small rocky coves, and gives views across to the Îles de Lérins. In September, the lower sun angle lights the Esterel mountains in deep reds and oranges during late afternoon.
26°C versus 30°C in July-August makes a 2-hour coastal walk comfortable rather than punishing. The path is far less crowded, and the September light on the Esterel is notably different from summer's harsh midday glare.Visiting Île Saint-Honorat and the Abbaye de Lérins
cultureThe smaller Lérins island is home to a working Cistercian monastery, the Abbaye de Lérins, where monks have made wine and liqueur since the 5th century. You can walk the entire island in about 45 minutes. The monastery's small shop sells their Lérins wines and the herbal liqueur Lérina. The island has a particular stillness, a 20-minute ferry ride from Cannes but a different world entirely.
September is harvest season on the island's small vineyards. The monks' grape harvest typically happens in the first half of September. Visitor numbers drop sharply from August.Booking tipFerries from the Vieux Port run less frequently than to Île Sainte-Marguerite. Check the schedule in advance and plan for 2-3 hours on the island.
Watching the sunset from the ramparts of Le Suquet
sightseeingThe old quarter of Le Suquet rises on a hill above the Vieux Port, and the 11th-century Tour du Suquet offers a 360-degree view over Cannes, the bay, and the Esterel massif to the west. In September, the sun sets directly behind the Esterel's volcanic red peaks. The narrow streets below have restaurants with terraces where you can eat while the light changes.
September sunsets hit the Esterel mountains at a lower angle than in high summer, producing more dramatic red-and-orange colours. The restaurant terraces in Le Suquet are no longer packed 3-deep, so a table with a view is actually possible.Booking tipNo booking needed for the ramparts. For a terrace table at a Le Suquet restaurant with a west-facing view, call the same day rather than walking in.
Journées Européennes du Patrimoine building access
cultureOn the 3rd weekend of September, France opens hundreds of normally closed heritage buildings to the public for free. In Cannes, this typically includes Belle Époque hotel interiors along La Croisette, rooms inside the Palais des Festivals beyond the usual public areas, private villas in the Californie quarter, and the historic chapels of Le Suquet.
This event happens only once per year, on the 3rd weekend of September. There is no other opportunity to enter many of these buildings.Booking tipSome sites require advance registration through the Journées du Patrimoine website. The most popular buildings (private villas, hotel interiors) fill their time slots within days of the programme being published.
What to eat in September
In season: fruit
Figues de Solliès
Var department PDO figs reach peak ripeness in September. The Solliès variety has deep purple-black skin and a jam-like interior that collapses sweetly when you bite through. Marché Forville vendors sell them by the tray. They pair well with fresh chèvre from the same market stalls.
Muscat de Hambourg grapes
September is vendange (harvest) month across Provence. These dark-skinned table grapes appear at Marché Forville and the smaller markets, with an intense floral sweetness you won't find in supermarket varieties. The Var and Bouches-du-Rhône departments are the main growing areas.
On menus now
Ratatouille provençale
September brings the final overlap of the summer vegetables this dish depends on. Aubergines, courgettes, tomatoes, and peppers are all still in season at Marché Forville but reaching their last weeks. The flavour concentration in late-season tomatoes tends to be more intense than in July's larger, waterier fruit.
Street food peaks
Socca
Thin, crispy chickpea-flour flatbread cooked in wood-fired ovens, a street food shared with Nice. September's 26°C weather makes eating socca at outdoor stalls near Marché Forville far more comfortable than in the 30°C+ heat of July. The edges should be charred and the centre still slightly soft.
Pan bagnat
Nice's signature sandwich, a round bread roll soaked in olive oil and filled with tuna, anchovies, hard-boiled egg, raw vegetables, and Niçoise olives. September's tomatoes and peppers are at their most flavourful. Bakeries and market stalls around Forville and Le Suquet sell them from mid-morning.
What to drink
Côtes de Provence rosé
The pale, dry rosé that defines Provençal summer drinking is still at its best in September. Terraces along La Croisette and in Le Suquet serve it well-chilled. The 18°C evenings feel purpose-built for outdoor glasses. Buying bottles at a supermarket on Rue Meynadier costs a fraction of terrace prices.
Regular events in September
Journées Européennes du PatrimoineFree
France's annual European Heritage Days open normally restricted buildings to the public. In Cannes, expect access to Belle Époque hotel lobbies, private chapels, and selected rooms in the Palais des Festivals. Free entry at all participating sites. The programme for Alpes-Maritimes is published about 2 weeks before the event.
3rd weekend of September (Saturday and Sunday, September 19-20 in 2026)Les Régates Royales de CannesFree
One of the Mediterranean's most prestigious classic yacht regattas, organized by the Yacht Club de Cannes. Over 100 classic and modern racing yachts compete in the Bay of Cannes across 5-6 days. The races are visible from La Croisette and the port breakwater. The atmosphere in the Vieux Port each evening, with crews socializing on their boats, has a particular end-of-season feel.
Last week of September (typically September 22-27)Best places this September
Île Sainte-Marguerite
islandThe larger Lérins island, 15 minutes by ferry from the Vieux Port. Fort Royal (the Man in the Iron Mask prison), eucalyptus forests, and south-facing swimming coves with some of the clearest water on the coast. In September the trails are shaded and cool, the water is warm, and the August day-tripper queues have disappeared.
Îles de LérinsMarché Forville
marketCannes' main covered market, open Tuesday through Sunday from 7:00. September brings the year's best produce overlap, with Solliès figs, muscat grapes, and the tail end of summer's tomatoes and courgettes. Monday is brocante (flea market) day. The stalls sit under a 1930s concrete roof in the Forville quarter, a 2-minute walk uphill from the Vieux Port.
ForvilleLe Suquet
neighborhoodCannes' original fishing village, perched on the hill above the Vieux Port. Narrow cobbled streets climb past restaurants and small galleries to the 11th-century Tour du Suquet and the Église Notre-Dame d'Espérance. In September the terraces have space and the lower afternoon sun picks out the warm stone of the buildings. The Musée de la Castre, housed in the medieval castle at the top, holds Mediterranean antiquities and ethnographic collections.
Le SuquetCroix des Gardes
parkThe highest point in Cannes at 164 metres, a protected natural area of Mediterranean scrubland, parasol pines, and wildflowers in the western part of the city. The walk up takes 20-30 minutes and gives a panoramic view over the bay, the Îles de Lérins, and the Esterel massif. September's 26°C makes this hike comfortable. Almost no tourists visit.
CaliforniePlage du Midi
beachThe long, wide public beach running west from the Vieux Port toward La Bocca. Less famous than the La Croisette beaches, with more space, fewer private concessions, and a distinctly local atmosphere. The sand is coarser than the groomed La Croisette strips, and the views west toward the Esterel mountains catch the September sunset directly. Free, with no reservation needed.
La BoccaCentre d'Art La Malmaison
galleryA contemporary art gallery housed in a former wing of the Grand Hotel on La Croisette. It hosts 2-3 temporary exhibitions per year in airy, light-filled rooms. September typically falls within an autumn exhibition run. The building itself, a remnant of Belle Époque Cannes, is worth the visit even before you see the art.
La CroisetteÎle Saint-Honorat
islandThe smaller Lérins island, home to the Abbaye de Lérins, a working Cistercian monastery since the 5th century. Monks produce wine from small vineyards and the herbal liqueur Lérina. September coincides with their grape harvest. The island takes about 45 minutes to walk around, and has a quiet intensity that the larger Sainte-Marguerite lacks. The monastery shop sells their wines directly.
Îles de LérinsMusée de la Castre
museumHoused in the medieval castle at the top of Le Suquet, the museum holds Mediterranean antiquities, pre-Columbian art, and ethnographic collections from Oceania and the Himalayas. The Tour du Suquet next door offers a 360-degree view of Cannes, the bay, and the Esterel. In September the hilltop catches a breeze that the streets below miss entirely.

Insider tips
The Yachting Festival week (second week of September) inflates hotel prices across the coast. Staying in La Bocca or Le Cannet, both within 10-15 minutes of the Croisette by bus, cuts accommodation costs by 30-40% compared to La Croisette-facing properties.
Marché Forville on a weekday morning in September has the year's best fig selection. Arrive before 9:00 and look for the Solliès AOC variety from Var growers. The stalls closer to the Rue Meynadier entrance tend to have the freshest produce, as those vendors arrive earliest.
Local Côtes de Provence rosé bought at the Monoprix on Rue Meynadier or at Nicolas wine shops costs a fraction of what the same bottles run at La Croisette bar terraces. A decent bottle starts around 7-10 EUR in the shop versus 10-15 EUR per glass on the waterfront.
The 3rd weekend of September (Journées du Patrimoine) gives free access to buildings that are closed all year, including Belle Époque hotel interiors and private villas in the Californie quarter. The Cannes tourism office publishes the local programme about 2 weeks before. Popular sites book out within days of the list going live.
For the best swimming in September, skip La Croisette's narrow public strips and take the ferry to Île Sainte-Marguerite's south-facing coves. The water is the same temperature but clearer, and you'll share the beach with a fraction of the people.
Avoid these mistakes
- Assuming every beach is free. Cannes has narrow public strips (plages publiques) between the private concessions on La Croisette, but the private sections charge for loungers and umbrellas. Plage du Midi west of the Vieux Port and the Île Sainte-Marguerite coves are free alternatives with more space.
- Booking an island day trip on a day with a yellow or orange weather alert. Mediterranean storms in September arrive fast, and the ferry service to the Îles de Lérins suspends without notice when conditions deteriorate. Check Météo-France the morning of your trip.
- Not reserving a restaurant for the Yachting Festival week. The 50,000 visitors fill every table in Le Suquet and along the Vieux Port. If you're in Cannes during week 2, book dinner at least a day ahead.
- Packing only summer clothes. The 18°C evenings and occasional rain catch travellers off guard who expect August weather in September. By the third week, you'll want a light jacket for dinner outdoors.
Practical tips for September
The Cannes Yachting Festival in the second week of September requires hotel bookings 2-3 months ahead, as 50,000 visitors fill properties from Monaco to Saint-Raphaël. Outside that week, same-week reservations are generally fine. Most restaurants and beach clubs remain on summer hours through mid-September, then start shortening schedules or closing for the season after the 15th. SNCF TER trains between Nice and Cannes run every 20-30 minutes and the ride takes about 30 minutes. Nice Côte d'Azur airport sits 25km east and has the widest selection of flights. Bus 210 (Lignes d'Azur) connects the airport to Cannes in about 45-60 minutes. Dress codes still matter along La Croisette more than in most French coastal towns. Restaurants and hotel bars there expect smart-casual at dinner. Tipping is not expected in France (service is included), but rounding up or leaving 1-2 EUR for good service at a café is common. French pharmacies in Cannes carry high-SPF sunscreen from La Roche-Posay and Avène, so you can buy locally rather than packing heavy bottles.
FAQ
Is September a good time to visit Cannes?
September is one of the two best months to visit Cannes, alongside June. The Mediterranean is at its warmest (23-24°C), crowds have thinned to roughly half of August levels, and hotel prices drop 30-40% from peak summer. The weather is still warm at 26°C (79°F) without July's oppressive heat. The main trade-off is more rain than summer, with about 6 rainy days averaging 62mm total, usually as short downpours rather than all-day grey.
What is the weather like in Cannes in September?
Expect average highs around 26°C (79°F) and lows near 18°C (64°F), with 62% humidity that rarely feels uncomfortable. Rainfall averages 62mm across 6 days, mostly as brief Mediterranean downpours. Early September still feels like summer. By late September, the evenings are noticeably cooler and the days shorter, with sunset around 19:15 compared to August's 20:45. The sea temperature, at 23-24°C, is the warmest of the year.
Can you still swim in Cannes in September?
September is actually the best month for swimming in Cannes. The Mediterranean has been absorbing heat all summer and reaches its annual temperature peak at 23-24°C (73-75°F). That is 3-4°C warmer than June, when many visitors find the water uncomfortably cool. The public beaches along La Croisette, Plage du Midi, and the coves on Île Sainte-Marguerite are all swimmable through the entire month.
Is Cannes crowded in September?
Compared to July-August, September is noticeably less crowded. The one exception is the second week, when the Cannes Yachting Festival brings around 50,000 visitors and fills the Vieux Port area. Outside that window, you'll find shorter queues at Marché Forville, more space on the public beaches, and available restaurant tables without booking. Les Régates Royales in late September draws a sailing crowd but has far less impact on the city than the Yachting Festival.
What events happen in Cannes in September?
The Cannes Yachting Festival (second week, typically September 9-14) is the month's biggest event and Europe's largest in-water boat show. Les Régates Royales de Cannes (last week of September) brings classic yacht racing to the bay. On the 3rd weekend, the Journées Européennes du Patrimoine opens normally closed heritage buildings across France for free, including Belle Époque hotel interiors and private villas in Cannes' Californie quarter.
