Weather in Toulouse in May

A good month. May is a solid month to be in Toulouse. Highs average 21.2 °C, lows 10.6 °C, and rain falls on 14 days — nothing in the month is working against you.

May ranks 4 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.

This is persistent light rain rather than storms: 14 wet days but only 2 heavy ones. It rarely cancels anything outright, and it rarely fully clears either. A jacket beats an umbrella. 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 May day reached 34.2 °C and the coldest night fell to 2.1 °C, and the wettest single day dropped 31 mm — roughly 36% of the month's rain in one day.

May is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest May on record still delivered 140 mm against 34 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 86 mm average is a reasonable planning figure, not a promise.

Wind is light at 8.5 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 76%, high enough to notice on the warm days without dominating them.

How May sits in the year

The month is on the way up: 3.5 °C warmer than April, and June adds another 5.4 °C. Late in the month feels noticeably different from the start of it, which is worth knowing if the trip is short.

Daylight in May

14.7 hours of daylight, gaining 1.1 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.

May in Toulouse versus nearby

If Toulouse is one option among several, the nearby comparison is worth making. Montpellier is a better bet in May — within a degree on temperature, 6 days less rain. Bordeaux is close enough to be a coin toss — within a degree on temperature, 2 days less rain.

So: May works, with September the better month by 9 points if the dates can move. If they cannot, nothing here should stop you booking.
