Direction for 4 weeks: summer vacation weather until August 21

by REGIS CREPET, meteorologist

Every week, the monthly weather trend is updated. This covers the period from July 25 to August 21 and relates to major summer school holidays as well as the end of the harvest season and the start of the grape harvest. This trend highlights a slight decrease in heat next week, except for the Southeast. A new peak of high heat should occur in early August followed by a few thunderstorms. The drought will continue. Thunderstorms are not expected to make up for the shortfall.

Very hot and always dry weather has settled over the country since the beginning of July, except for a few stormy rains which are not enough to make up for the drought. If temperatures drop a bit during the week, this July should rank among the 3 hottest and driest since the beginning of weather records.

The week of July 25-31: heat is more bearable but still rainy…

The last week of July will see more mixed and cooler weather with the direction of flow from west to northwest sector accompanied by ocean air. However, time will not be disturbed; Count on fewer long days of good weather with cloudy periods but little rain or thunderstorms. Heat will become bearable again, except in the southeast where high temperatures are expected to continue with a high risk of fires on windy days.

first weekVerse Until August 7: a new peak of high temperatures followed by thunderstorms

A cold drop could form off Portugal, again raising fears of warming from the southwest. It’s hard to be precise at this time, but the level of temperatures in the country will again depend on the position of this cold dip. A priori, the south will be hardest hit by rising temperatures, even if temperatures rise temporarily in the north. A cold dip, this time, can lead to instability with windy and stormy weather. Again, these storms will spread and not everyone has to be in the same boat.

Week from August 8 to 14: Summer weather with reasonable heat

Nice summer weather should prevail over the country next to an anti-cyclone in the British Isles. The sun will prevail over most of our regions with a few heat storms at most at the end of the day in the south and east of the country, especially near the bass. Temperatures will return a little lower but still above seasonal standards.

Week 15-21 August: Unstable and stormy weather in the south

The third week of August may see the weather become unstable in the south with frequent stormy rains from the Alps to the Mediterranean hinterland as well as near the Pyrenees. The reliability of this weather trend remains limited at this time, but this unstable trend will be good news for regions affected by severe and prolonged drought. The northern half of the country can remain under the influence of anticyclonic conditions with fairly dry and sunny weather.

So this July will end with a clear deficit of rainfall despite the few expected storms. Temperatures will decrease slowly, while remaining above normal for the season. Early August could be warmer again with the specter of sweltering heat, at least in the south. So it will be necessary to monitor this period. Finally, we should find cooler conditions in the second ten days of August with more windy weather in the south.

Next update, Thursday, July 28 at 5pm.
