Weather in Toulouse in August

A good month. August is a solid month to be in Toulouse. Highs average 30.1 °C, lows 17 °C, and rain falls on 10 days — nothing in the month is working against you.

August ranks 7 of 12 in Toulouse: past the worst of the year but short of September, which is the month to book if the dates are open.

Rain on 10 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 30.1 °C days and 17 °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: 5 days clear 35 °C, so a serious heatwave is normal rather than notable. Across the twenty years measured, the hottest August day reached 42.2 °C and the coldest night fell to 10.5 °C, and the wettest single day dropped 27 mm — roughly 53% 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 81 mm against 22 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 51 mm average is a reasonable planning figure, not a promise.

Wind is light at 7.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 59%.

How August sits in the year

Temperatures hold steady either side: 29.9 °C in July, 30.1 here, 26.1 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 Toulouse's extremes of 15.4 and 9 hours, so days are long enough not to constrain the plan.

An inland climate

With no coast nearby, the year swings a fair way — 27.9 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

How busy it gets

Busy. Popular without being frantic; book the things you care about, improvise the rest.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

August in Toulouse versus nearby

If Toulouse is one option among several, the nearby comparison is worth making. Montpellier is a better bet in August — within a degree on temperature, 5 days less rain. Bordeaux is a better bet in August — 2.3 °C cooler, 1 day less rain.

So: August works, with September the better month by 15 points if the dates can move. If they cannot, nothing here should stop you booking.
