Weather in Paris in August
France · 20-year averages, August
Prime time. If you get to pick your dates, August is the one. Highs average 24.9 °C, lows 13.6 °C, and rain falls on 11 days — nothing in the month is working against you.
August ranks 3 of 12 in Paris. Only September scores clearly higher, and the difference is small enough to be settled by price rather than weather.
Rain on 11 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.
What the averages hide
The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest August day reached 38.3 °C and the coldest night fell to 7.1 °C, and the wettest single day dropped 30 mm — roughly 51% of the month's rain in one day.
August is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest August on record still delivered 98 mm against 12 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 59 mm average is a reasonable planning figure, not a promise.
Wind is light at 8.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 72%.
How August sits in the year
Temperatures hold steady either side: 25 °C in July, 24.9 here, 21.7 in September. Nothing about the timing within the month matters much.
Daylight in August
14.4 hours of daylight, losing 1.6 hours across the month. That is between Paris's extremes of 16.1 and 8.3 hours, so days are long enough not to constrain the plan.
An inland climate
Despite being inland, the year stays fairly even: 24.4 °C between the year's warmest afternoons and coldest nights.
How busy it gets
Peak season. Expect the highest prices of the year and to be booking well ahead.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
August in Paris versus nearby
If Paris is one option among several, the nearby comparison is worth making. Le Havre is close enough to be a coin toss — 4.2 °C cooler, 1 day more rain. Lille is close enough to be a coin toss — 2 °C cooler, 2 days more rain.
So: August is effectively as good as it gets here — 3 points behind September, which is inside the margin where the weather stops being the deciding factor and price starts being it.
