What Is the Climate Like in Tarn-et-Garonne?
It is important to first understand that the Tarn-et-Garonne department is located halfway between the Massif Central (which generates mountainous influences) and Gascony, which generates a mild climate. This allows the territory to benefit from the wildness and harshness of the Causse as well as the richness of the Garonne plains.
Thus, the fact that the department is halfway between the Atlantic Ocean and the Mediterranean Sea means that the Pyrenees and the Massif Central strongly influence the climate of Tarn-et-Garonne, making it oceanic and degraded.
This type of climate mainly produces a mild and humid winter, also interspersed with slightly cool periods, meaning there are 37 days of frost throughout the entire territory of department 82, specifically in Montauban. It could even reach -5°C. The winter period is consistently cold, causing winters to reach temperatures as low as -10°C. There is also a rarity of snowfall and rainfall is scarce.
When we talk about the summer period, on the other hand, we see many high temperatures and also a dry period. Sometimes, during this season, temperatures reach 30°C in the shade for 20 days or more per year. Regarding precipitation, rains are mainly generated by winds coming from the western part of the Tarn-et-Garonne department. Moreover, this amount of rain never exceeds 646 mm, specifically in the town of Monbéqui, which is also the least rainy part of the department.
But when we talk about other regions, on the other hand, it rains much more, about 836 mm in the commune of Montaigu-de-Quercy. Furthermore, in the western part of the department, more precisely in the northwest, there are 941 mm of precipitation.
Rains mainly occur during the winter and spring periods. There are also thunderstorms and sometimes a lot of hail in spring and autumn. During these periods, in Montauban, there are 425 mm of precipitation, but sometimes these rains reach up to 1000 mm. Regarding winds, they are numerous and mainly come from the west; in Montauban, winds can reach 119 km/h.
