The expected wave of sweetness has indeed taken place. It was even quickly reclassified as a heat wave, with values ​​regularly exceeding the famous 25°C threshold. New records were thus broken, this was particularly the case on Thursday afternoon between the Center, Lorraine, Normandy and Auvergne regions.. The city of Le Mans recorded a maximum of 26.6°C, unheard of in the third decade of October, the old record of 24.8°C set on October 27, 2005 having been largely beaten. Same observation in Alençon with 23.6°C recorded, in Villemurlin (Loiret) with 25.2°C or even in Seingbouse (Moselle) with some 22.6°C under shelter. On a national scale, Thursday was the hottest day during the whole month of October with a thermal anomaly of +6.5°C. !

Also the following night, the thermometers remained at exceptional levels for the season, in particular thanks to the southerly wind. Thus, in Biscarrosse (Landes), they did not fall below 21.5°C, a new record for the month of October (old record: 21.2°C on October 6, 2009). Several high-altitude resorts also broke their monthly record for nighttime mildness, proof that the hot air mass overhanging France is unprecedented for this time of year.. During the coolest hours, it was no less than 14.2°C at Super-Besse (Puy-de-Dôme, 1287 m), 15.8°C at La Pesse (Jura, 1133 m), 17 7°C at Saint-Gervais-d’Auvergne (Puy-de-Dôme, 705 m) or 18.5°C at Saint-Nicolas-des-Biefs (Aller, 1022 m), levels worthy of high summer .

Rebelote Friday afternoon with new monthly records established between the Basque Country and the Massif Central. The values ​​reached in Auvergne are exceptional with in particular 26.8°C in Puy-en-Velay (Haute-Loire) and even 28.6°C in Courpière (Puy-de-Dôme), a value that is all the more remarkable since the previous monthly record had been beaten at the beginning of the month, on October 4, 2004 precisely. In the Pyrénées-Atlantiques too, the maximums were indecent for the end of October with some 32.2°C reached at Ger, i.e. 14°C more than normal for the season! During the day, the national thermal indicator reached 19.45°C, a value worthy of June 20 or August 29!

In many cities, late heat records have been set. In other words, never had 25°C been reached so late in the fall.. This was the case in Lyon with 25.3°C on October 28, in Besançon with 25.8°C, in Clermont-Ferrand with 28.7°C, in Nancy at 25.1°C, in Colmar with 27° C or even in Rodez with 25°C to name but a few examples. These values ​​have contributed to making this month of October even more exceptional, as temperatures have been constantly above normal since the beginning of the month. Thereby, it ranks first among the hottest months of October with an average of around 17°Coutclassing October 2001 which held the prize until then.

With 31.8°C on Saturday afternoon, Tarbes experienced another very hot day (>= 30°C), which brings the annual total to 48 days for a 1991-2020 average of 15 days whereas in 1977, there had been none! Moreover, before 2022, 30 degrees had never been reached in the 3rd decade of October. This Saturday, peaks of 33°C were even observed at the foot of the Pyrenees. From this Sunday, more oceanic air will drive out subtropical air. Temperatures will thus gradually drop until All Saints Day. to find (finally) the normal of the season. But a new wave of sweetness is already foreseen for next weekend!
