What Is The Hottest Month In Toulouse?

Toulouse, the pink-brick city on the Garonne in southwestern France, is at its warmest in August. That answer surprises some planners, because July is the month everyone talks about when they picture a southern French summer. The official numbers say otherwise, and they come from a single, precise source: Meteo-France's 1991-2020 climate normals for the Toulouse-Blagnac weather station, the reference dataset the national forecaster publishes for this exact location.

What Is The Hottest Month In Toulouse?

August is the hottest month in Toulouse, with a mean temperature of 22.8C across the 1991-2020 normals, just ahead of July at 22.6C. August also posts the higher mean daily maximum, 28.5C against July's 28.2C, while July stays the sunnier and drier month of the two. The all-time record high, 42.4C, was set on 23 August 2023.

The gap between the two peak months is real but small, half a degree on the monthly mean and three tenths on the daytime high. What that means in practice is that the last week of July and the first three weeks of August feel essentially the same: warm mornings, hot afternoons, and evenings that stay pleasant because the mean daily minimum in August is 17.1C. July's nights are a whisker cooler at 17.0C.

For trip planning, the more useful distinction is not July versus August but July-and-August versus everything else. June already averages a mean daily maximum of 25.7C, and September only drops to 24.8C, so the warm season in Toulouse is long, wide, and forgiving at both ends. A visitor arriving in mid-June or mid-September experiences a city that is unmistakably summery, without quite the same concentration of 30C days.

It is also worth being clear about what "hottest" means, because three different measures give three slightly different answers. On the monthly mean temperature, August wins at 22.8C. On the mean daily maximum, August wins again at 28.5C. But on sunshine hours, July wins decisively with 258.6 hours against August's 246.4, and on rainfall July is drier too. Anyone choosing between the two months on weather alone is really choosing between marginally more heat and noticeably more sun.

How Hot Do Summer Days In Toulouse Actually Get?

The mean daily maximum in August is 28.5C and in July 28.2C, and those two months each average around eleven days per year at or above 30C, 11.5 in July and 11.3 in August. June averages six such days and September three and a half. The 30C threshold is therefore a regular summer feature in Toulouse, not an exception, but sustained extreme heat is rarer.

Here is the monthly picture from the Meteo-France 1991-2020 normals, mean daily maximum and minimum in degrees Celsius:

Two readings of that table matter. First, the heat builds steadily rather than arriving all at once: each summer month is roughly three to four degrees warmer than the one before it until August, and then the decline is equally gradual. Second, the nights are what shape how the heat feels. A 28C afternoon followed by a 17C night is a very different experience from the same afternoon followed by a 22C night, and Toulouse's summer nights sit firmly in the comfortable camp.

The record books underline that this is a city capable of genuine extremes, even if they are uncommon. The all-time high for the station, covering records from 1947 to June 2025, is 42.4C, recorded on 23 August 2023. The all-time low, for perspective, is -19.2C on 15 February 1956. Toulouse is a continental-influenced city far from any coast, so its thermometer has a wide range; the sea that would moderate temperatures is simply not there, the Atlantic and the Mediterranean are both hours away.

Is July Or August Better For Visiting Toulouse?

July is the better of the two for most trips: it is the sunniest month of the entire year at 258.6 hours of sunshine, and it is drier, with only 40.1 mm of rain across the month against August's 44.6 mm. August is marginally hotter on paper, but July delivers more sun and slightly cooler nights, which matters more for sightseeing than half a degree of daytime mean.

August holds one practical advantage: it is the month when a substantial share of local residents take their own holidays, so the city's rhythm shifts. Some independent shops close, and certain neighborhoods feel quieter. Whether that is a bonus or a drawback depends on the trip. A first visit built around the major sights, the Basilique Saint-Sernin, the Capitole, the Jacobins and the riverside, works well in either month. Everything else covered here is indexed on Toulouse Travel Guide.

If the plan is a walking-heavy stay, and Toulouse rewards walking, then the July-or-August question becomes a morning-and-evening question. The Toulouse Must-see Walking Tour covers the compact historic center on foot, and summer walkers do best booking the earliest or latest departure of the day; Check availability for the timed slots. The same logic applies to any self-guided wandering: the pink brick photographs beautifully in low morning and evening light anyway, and the harshest glare comes at midday.

One more summer consideration sits outside the thermometer entirely. Toulouse's cultural calendar keeps running through the hot months, and the events that were confirmed on official city pages include Piano aux Jacobins from 8 to 30 September 2026 and Toulouse les Orgues, the festival's 31st edition, from 7 to 18 October 2026, with the opening concert on 7 October at Notre-Dame de la Daurade. Neither falls in the hottest window, but both give late-summer visitors a reason to extend a stay into the shoulder season, when the heat has eased and the light is still generous.

When Is Toulouse Too Hot For A City Break?

Toulouse is rarely too hot for a city break if the day is shaped around the heat: mornings and evenings are pleasant even in August, with mean daily minimums above 17C, and the city's shaded squares, museums and riverside paths offer midday refuge. Travelers sensitive to heat should simply avoid planning long outdoor stretches between roughly 13:00 and 17:00 in July and August, the window when the 30C-plus days cluster.

The heat here is dry rather than humid, which visitors find easier to handle, and the eleven-or-so days at or above 30C each July and August are spread across the month rather than stacked. A sensible hot-day pattern looks like this: an early start outdoors, a long shaded lunch, an air-conditioned museum or an indoor attraction in the early afternoon, and the evening outdoors again, when terraces fill and the light turns gold on the brick.

Warm afternoons are easier on two wheels. Book an e-bike tour here.

The indoor hours have plenty of options. The city's museum and attraction pages on this site are the practical resource: the Musee des Augustins, the Fondation Bemberg and the air-and-space attractions all sit within easy reach of the center. Note one seasonal quirk worth checking before any museum visit: the Musee des Augustins is temporarily closed from 21 September to 2 October 2026 for great-cloister works, with its Gothic halls reopening on 3 October 2026, so late-summer and autumn visitors should confirm opening days. The Couvent des Jacobins, another indoor landmark, is free on the first Sunday of the month except when a temporary exhibition is on, a detail the city's own page for the convent states.

How Does The Heat Change What You Do In Toulouse?

The heat changes the schedule more than the itinerary: the same sights work in summer, but the day inverts, with outdoor exploration before noon and after 18:00, and indoor hours in between. Water matters too, and the Garonne riverside and the city's parks become the evening's main stage, while day trips to the Pyrenees, roughly 100 km south, offer a genuine escape from the heat at altitude.

The evening economy of Toulouse is built for exactly this pattern. Terraces, the riverside quays and the Saint-Aubin and Carmes neighborhoods come alive late, and dinner habits shift accordingly. The question of how many days is enough for Toulouse has the same answer in summer as in any season, two days for the core sights, three or more with day trips, but summer days hold fewer usable outdoor hours at midday and more usable ones at night.

For anyone who wants a hard reset from the heat, the mountains are the obvious lever. The Pyrenees sit roughly 100 km south of the city, and the closest city to the Pyrenees question is one this site answers in detail. A morning departure, cooler air by lunchtime, and a return to a warm Toulouse evening is a realistic single-day shape in July or August.

Common Questions About Summer Heat In Toulouse

Is Toulouse Humid In Summer?

The climate normals track temperature, rain and sunshine rather than humidity, so no humidity figure can be stated from the verified data. What the data does show is that July and August are comparatively dry months, with 40.1 mm and 44.6 mm of rain respectively.

Does It Cool Down At Night In Toulouse In Summer?

Yes, moderately. The mean daily minimum is 17.0C in July and 17.1C in August, which keeps evenings pleasant for terraces and riverside walks after hot days.

Is June Or September Hotter In Toulouse?

June is hotter, with a mean daily maximum of 25.7C against September's 24.8C. Both are warm, sunny months, and both are fine for a full outdoor itinerary.

Whichever of the two peak months a trip lands in, the practical advice is identical: book the outdoor activities early, hold a shaded or air-conditioned option for the early afternoon, and leave the evening open for the riverside. The guided options above cover both halves of that plan, a walking tour of the center for the cool hours and indoor attractions for the hot ones.

August is the hottest month in Toulouse, but only by a margin so thin that July, with its extra sunshine and slightly drier profile, is the better pick for most summer visits. Either way, the pattern is the same: out early, in at midday, and back outside for the long, warm evening the pink city does best. For the other end of the thermometer, see what is the coldest month in Toulouse, and for the rain question, does it rain a lot in Toulouse has the answer from the same normals.
