Paris in August: 26°C afternoons, 16°C mornings, 8 rain days, 215 sunshine hours — climate twin to July, but half the locals are away.
August is Paris in a strange mood. Météo-France climate data put the afternoon at 25.6°C and the morning at 16°C, with about 8 rain days and 215 hours of sunshine. The climate is nearly identical to July, but the city feels different: most Parisians are on vacation (the August 15 Assumption holiday marks the peak exodus), many small boutiques and family restaurants close for 2-4 weeks, and the city fills with international tourists. What this means for dressing: the Parisian-local crowd thins out, so 'what the locals wear' matters less than 'what reads Paris-authentic to cameras and other visitors.' Lean into the classic Paris summer uniform: linen, a silk camisole, wide-leg trousers or a midi skirt, flat leather sandals, a straw tote. Afternoon thunderstorms are slightly more frequent than July; a compact umbrella stays in the bag. Evenings at 16°C still call for a light layer along the Seine.
August is Paris in a strange mood — locals on vacation, 'fermeture annuelle' on half the windows, international tourists filling the gap.

The August Paris piece. Cream, white, or pale butter yellow. Sézane, Dôen, or Reformation. Moves in heat, reads Paris in every photo.

For dinner reservations and air-conditioned museums. The silk cami reads polished under the trousers and cool in 26°C heat.

The classic Paris tourist avoidance uniform. Stripes read considered, not tourist-costume. Denim mini or midi skirt beats shorts.

Evenings cool to 16°C along the Seine; Métro is still hot. A linen blazer handles both; a silk scarf is the Parisian compromise.

Two pairs. Leather sandals (The Row, Ancient Greek, Hereu) for evenings and cobblestone afternoons; clean white sneakers (Veja, Adidas Samba) for museum days.

August is the one Paris month a straw tote reads elegant rather than touristy. Farmers market, Tuileries chairs, a book for the park.

Tourist crowds peak August. A zipped crossbody close to the body handles Louvre queues and packed Métro cars better than the tote.

8 rain days, usually afternoon showers. Oversized sunglasses for the Seine reflection and 215 hours of August sun.
Breton tee · denim skirt · white sneakers · straw tote. Sacré-Cœur at 9am before tourist peak, croissants in Montmartre.

Linen midi dress · leather sandals · linen blazer · crossbody. Dinner at a Saint-Germain bistro still open in August, Seine walk at sunset.
Per Météo-France climate data (Parc Montsouris): average daily high is 25.6°C (78°F), low is 16°C (61°F). About 8 rain days with 58mm total rainfall, plus 215 hours of sunshine. Heat waves in recent years have pushed August days above 35°C occasionally; check forecasts. Generally similar to July but with more afternoon thunderstorms.
Yes, with asterisks. The climate is pleasant, the city is quieter in residential neighborhoods (locals on vacation), and long evenings persist. The trade-offs: many beloved local restaurants and boutiques close 2-4 weeks for 'fermeture annuelle' (annual closing), tourist attractions are packed, and hotel prices peak alongside June. Book restaurants well in advance and check if your favorites are open.
A light layer, yes. Evenings at 16°C and Seine-side breezes call for a linen blazer, silk scarf, or a lightweight cardigan. Restaurants and museums also run strong air conditioning in August heat waves. A packable layer in your bag is daily-use.
A linen midi dress, linen trousers with a silk camisole, or a slip dress with a structured sandal. Nothing too technical or athletic. Bring a silk scarf or light blazer for the 9-10pm cool-down when the sun finally sets. Paris terrace dining runs late — plan for the 10pm temperature, not the 8pm one.
Heavy winter-weight fabrics, athletic shoes with large logos, flip-flops, cargo shorts, rubberized rain jackets. Also skip bringing only one pair of shoes — August cobblestones punish any single pair over 20,000 steps a day. A sandal + sneaker combination covers the whole trip.
