After flirting with the 40 degrees at the start of the week, the mercury should descend “spectacularly” to Bordeaux And surroundings, according to meteorologist Guillaume Séchet.
In 24 hours, temperatures will drop by a dozen degrees due to “A change in radical air mass”. “A west wind will chase the Saharan air mass in recent days,” said the founder of Météo-Villes.
No thunderstorms expected
In other words, an ocean wind will replace a southern, warm and continental wind. However, Guillaume Séchet does not provide thunderstorms. “It takes a conflict of air masses at high altitude but there, the fresh air from the Atlantic will be in the atmospheric low layers, at the level of the soil,” he develops.
Thanks to this west wind, temperatures should not exceed 28 degrees in Gironde. Météo France even announces maximums at 25 degrees on the coast, especially in the Arcachon basin, i.e. Compliant with seasonal averages While the mercury sailed 12 to 13 degrees above normal in recent days.
However, heat may not be absent for very long. Thursday, July 3, Météo France plans 33 degrees in Bordeaux and even 36 degrees on Friday July 4. On the other hand, the start of next week looks softer With maximum maximum at the 30 degrees threshold.
