It's quite a surprising phenomenon that has taken hold of part of France since this Thursday, May 21. Indeed, over the weekend, we’re seeing a rise in temperatures across the continent, exceeding seasonal norms by 10 to 15°. And I can tell you that with the arrival of the ice saints, it certainly makes us want to break out the sandals, shorts, and caps again. However, this meteorological change can be explained quite rationally.
A wind coming straight from the south
Once again, as is always the case when talking about the weather, it's all about the wind. In fact, a flow of warm air from Morocco is currently over France. But there you go, this...The heat wave gets trapped under the high pressures of a powerful anticyclone. We might not fully understand all those technical terms either, but the bottom line is that these phenomena create a "heat dome", leading to a sharp rise in temperatures over the next few days. Basically, the anticyclone acts like the lid of a pot, blocking the hot air and making the temperature rise higher and higher, causing meteorological records to be set across the country.
C’est quoi ce "dôme de chaleur" à l’origine d’une augmentation spectaculaire des températures en France

A Beautiful Weekend Ahead
In Toulouse, the thermometer will hit around 35°C, and this will last until the end of next week. To top it all off, there won’t be a cloud in the sky to spoil this exceptional weather, giving us a sweet taste of summer, and importantly, allowing us to dry out after weeks of relentless rain. Plus, it’ll be a great training for what’s to come, as experts agree: due to climate change, these heatwaves are likely to become more frequent in the years ahead.
Le problème c'est même pas la chaleur, le problème c'est qu'on est passé de 10 à 30 degrés sans aucune transition wow
