0 mm of rain from July 1 to August 15

Even if it rains on Sunday June 26, which usually falls in a month in Puy-de-Dôme, it will not be enough. The month of July is particularly dry with a cumulative rainfall of 2.4 mm. “Of course, this is the driest month of July since the beginning of surveys in the department because it has dropped to an average of 55 to 80 mm in a normal month of July”, continues Christophe Mertz. Locally, not a single shower fell between July 1 and August 15, which was a very long and completely dry period.

The drought does not end in Puy-de-Dôme: “We look at the clouds to see if they will fall with us” (November 2022)

Rainfall is low the rest of the time and the year is particularly dry with an average annual total of 465 mm. “This is the lowest annual rainfall total since 1975, behind 1989 (325 mm) and 2015 (379 mm)”, recalled the meteorologist.
