Weather in Montpellier in July
France · 20-year averages, July
Prime time. July is about as good as Montpellier gets. Highs average 29.9 °C, lows 19.6 °C, and rain falls on 4 days — nothing in the month is working against you.
July ranks 4 of 12 in Montpellier: past the worst of the year but short of June, which is the month to book if the dates are open.
Rain falls on only 4 days, so an itinerary with no wet-weather fallback is a reasonable risk. Pack for 29.9 °C days and 19.6 °C nights; the spread matters more here than any single number.
What the averages hide
Averages flatten a month, and this one hides a few things: 15 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest July day reached 36.9 °C and the coldest night fell to 13.3 °C.
This is the volatile part. July rainfall has ranged from 4 mm to 58 mm across the twenty years measured — a 54 mm spread around an average of 20 mm. The average is real but almost no individual July looks like it, so treat the figure as the middle of a wide range rather than a forecast.
Wind is light at 11.1 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 57%.
How July sits in the year
Temperatures hold steady either side: 27 °C in June, 29.9 here, 29.6 in August. Nothing about the timing within the month matters much.
Daylight in July
July is at or near the longest days of Montpellier's year: 15.1 hours of daylight, losing 0.7 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.
Sea temperature
The sea sits at about 21.9 °C in July — comfortable for a proper swim. 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, April is the trade worth considering — 11 points weaker on weather, and materially quieter.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
July in Montpellier versus nearby
If Montpellier is one option among several, the nearby comparison is worth making. Marseille is the weaker option in July — 3.3 °C warmer, 1 day less rain. Toulouse is the weaker option in July — within a degree on temperature, 5 days more rain.
So: July works, with June the better month by 8 points if the dates can move. If they cannot, nothing here should stop you booking.
