Your August weather guide
WarmWeather in Paris in August
August is a good choice for Paris if you want warm days without relying on constant sunshine. Average highs of 24°C suit spending time outdoors, while nights around 15°C make a light layer useful after dark. The catch is rain: about 9 days have measurable rainfall, so keep plans flexible. It suits travellers happy to mix outdoor time with indoor breaks, rather than those who need reliably dry holiday weather.

Warm rather than consistently hot
August is Paris's warmest month, but that does not mean every afternoon feels hot. Days reach 25°C around 38% of the time, while 30°C is reached on 9% of days. For most travellers, that makes light daytime clothing a sensible starting point, with room in the bag for an extra layer. On hotter days, move longer walks away from midday and leave yourself time to rest indoors. Evenings can feel quite different from afternoons: the coldest nights fall to around 12°C or below. If you tend to feel the cold, pack a jumper rather than assuming summer clothes will cover the whole day.
Keep outdoor plans flexible
Rain is a real consideration in August, not a reason to rule Paris out. With about 9 rainy days, a compact umbrella or light waterproof is more useful than a plan that depends on staying outdoors throughout. There is about 6 hours of sunshine within 14.2 hours of daylight, so long days should not be mistaken for uninterrupted sun. Leave outdoor plans movable and keep an indoor alternative in mind when rain is forecast. Light layers work well for this mix of warmth and changeable skies; a heavy coat is not the obvious choice for the average conditions. Pack for both sun and rain.
