What should I pack for St. Augustine?

Shoes with good tread matter more in St. Augustine than in most Florida beach towns. The streets through the Colonial Quarter are uneven, a mix of old brick, tabby, and coquina surfaces that crunch underfoot and turn slippery after rain. The pedestrian stretch of St. George Street runs about half a mile through the historic core, and you'll feel every uneven seam through thin soles. Castillo de San Marcos, the coquina-walled fort begun in 1672, has worn ramps and ground-level passages that get slick in summer storms. Flat sandals won't survive a morning at the Castillo. Broken-in trail shoes or hiking sandals with rubber grip handle the cobblestones, the wooden boardwalks on Anastasia Island, and the packed-sand trails at Fort Matanzas National Monument 14 miles south on A1A.

June through September in St. Augustine runs 30-33°C during the day with humidity around 80-85%. The air feels heavy and damp the moment you step outside, even at 8am, and your sunglasses will fog walking from an AC'd hotel lobby onto St. George Street. Pack 3-4 lightweight, quick-dry shirts and shorts. You'll likely want a fresh shirt after a morning at the Lightner Museum or after climbing the 219 steps of the St. Augustine Lighthouse on Anastasia Island. One light long-sleeve layer is worth bringing for the aggressive air conditioning inside restaurants along Avenida Menendez, where it can feel 15°C cooler than the sidewalk. Evenings along the Matanzas Bay waterfront settle to around 23-24°C with a salt breeze off the water, and you won't need a jacket from May through October.

Afternoon thunderstorms roll in off the Atlantic almost every day from June through September, typically between 2pm and 5pm. They hit with warm, heavy rain that drums on the coquina for 20-40 minutes, then clear to blue sky. A packable rain jacket beats an umbrella because you'll want both hands free on the Castillo's walls and the narrow sidewalks along Charlotte Street. SPF 50+ sunscreen is non-negotiable at outdoor sites like Castillo de San Marcos and Fort Matanzas, where shade is almost nonexistent and 2-3 hours of direct Florida sun will burn through lower SPF. Bug repellent with at least 20% DEET or picaridin matters most at dusk and near the salt marshes around Fort Mose, the 1738 settlement about 2 miles north of downtown. No-see-ums at St. Augustine Beach can be relentless from May through October. A DEET-based repellent handles both no-see-ums and mosquitoes better than the citronella sprays sold at the Anastasia Island beach shops.

Beach chair rentals along A1A at St. Augustine Beach run $10-15 per day, and umbrella rentals are $8-12, so leave those at home. Sunscreen at the CVS on King Street costs $8-12 for a name-brand SPF 50, roughly the same as back home, but it saves luggage space. Aloe vera gel runs $5-7 at the same CVS or the Walgreens on US-1. Cheap flip-flops for the sand go for $8-15 at the surf shops near the St. Augustine Beach pier. A reusable water bottle is worth the suitcase space, since the public refill fountains cluster around the Plaza de la Constitución and a cold refill makes a real difference when it's 33°C by mid-morning. That walk from the Cathedral Basilica to the Lightner Museum is about 10 minutes with no shade along Cordova Street.
