Weather in Nice in August
France · 20-year averages, August
Prime time. If you get to pick your dates, August is the one. Highs average 25.8 °C, lows 23.4 °C, and rain falls on 5 days — nothing in the month is working against you.
August ranks 2 of 12 in Nice. Only July scores clearly higher, and the difference is small enough to be settled by price rather than weather.
Rain falls on only 5 days, so an itinerary with no wet-weather fallback is a reasonable risk. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.
What the averages hide
Averages flatten a month, and this one hides a few things: it never really gets hot: not one day in an average August reaches 30 °C; the day barely swings — 2.4 °C between the overnight low and the afternoon high. Across the twenty years measured, the hottest August day reached 32.1 °C and the coldest night fell to 19 °C, and the wettest single day dropped 41 mm — roughly 178% of the month's rain in one day.
August is moderately variable: 5 mm in the driest year against 60 mm in the wettest, around an average of 23 mm. Roughly two Augusts in three land near that average, and the third does something else entirely.
Wind is light at 9.2 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 73%.
How August sits in the year
Temperatures hold steady either side: 25.5 °C in July, 25.8 here, 23 in September. Nothing about the timing within the month matters much.
Daylight in August
14 hours of daylight, losing 1.3 hours across the month. That is between Nice's extremes of 15.4 and 9 hours, so days are long enough not to constrain the plan.
Sea temperature
The sea sits at about 24 °C in August — warm enough to stay in as long as you like. This is the warmest the water gets all year.
How busy it gets
Peak season. Expect the highest prices of the year and to be booking well ahead. If the dates are flexible, May is the trade worth considering — 12 points weaker on weather, and materially quieter.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
August in Nice versus nearby
If Nice is one option among several, the nearby comparison is worth making. Genoa is the weaker option in August — 4.9 °C warmer, 2 days more rain. Marseille is the weaker option in August — 6.8 °C warmer, 1 day less rain.
So: August is effectively as good as it gets here — 2 points behind July, which is inside the margin where the weather stops being the deciding factor and price starts being it.
