What should I pack for Philadelphia?

Your shoe choice matters more in Philadelphia than in most American cities. Old City's streets between 2nd and 5th on Market and Chestnut are laid with Belgian block cobblestones that turn slick in the rain and punish thin soles. The Philadelphia Museum of Art, founded in 1876, will put 3-4 hours of walking on your feet in a single visit. You want closed-toe shoes with real tread, not fashion sneakers that look good for 2 hours. Flip-flops work on South Street in July, but they'll slow you down along Elfreth's Alley, where the uneven brick sidewalks date to the early 1700s.

Philadelphia summers are sticky. Mid-June through August, daytime temperatures sit around 30-33°C with humidity above 70%, and you'll feel the damp warmth on your skin the moment you step outside at 8 AM. Pack 3-4 moisture-wicking shirts. Cotton holds the sweat and you'll feel clammy before you reach Reading Terminal Market at 12th and Arch. That said, every indoor space runs its AC hard, somewhere around 18-20°C. The Barnes Foundation on the Benjamin Franklin Parkway keeps its galleries cool enough that you'll want a light layer after standing still for 20 minutes. A packable rain jacket handles both the AC chill and the afternoon thunderstorms that roll through 3-4 days a week from June through August.

A portable phone charger is the item most first-timers forget. Navigating SEPTA's subway and bus routes on Google Maps while photographing Independence Hall and the Liberty Bell, both dating to 1753, will kill a phone by 2 PM. Bring a refillable water bottle. The city installed public fountains along the Schuylkill River Trail and at LOVE Park. If you're visiting November through March, pack real winter layers. January averages sit between -3°C and 4°C, and the wind funneling between Center City's high-rises on Market Street adds a raw chill that the thermometer won't prepare you for. Spring and fall can swing 15°C in a single day. Layers still win outside of July and August.

Skip packing these and buy them on arrival. Umbrellas go for $5-8 at any Wawa, the regional convenience chain with a location every few blocks in Center City. Sunscreen and basic OTC meds cost less at the CVS on Broad and Walnut than at airport shops. Forgot a phone charger? The Five Below on Market Street has cables for $5. Toiletries are dead weight in your luggage. The Target on Chestnut Street in Center City stocks everything at normal retail, not hotel-gift-shop prices.
