The fourth heat wave promises to be intense and widespread throughout France

While some departments in the south-east of the country, such as Vaucluse, have seen no break in the vague of heat which started on 1^er August, a new heat wave is taking place this week. Once again it’s the same scenario repeating itself : a powerful anticyclone wins the North-West of Europe and traps on France theair warm that comes from North Africa.

An “omega” blockage, such as meteorologists call it, a situation often found in heat waves. This generates a dominant north-easterly flow over France, a wind which dries out the vegetation even more and increases the risk offires.

Temperatures will gradually rise day by day, from the south, in the center, to the north. The peak of intensity of this fourth heat wave should occur on Friday and Saturday with values ​​equal to or greater than 40°C in the southwest, and 36°C over the northern half and the Paris region.

Unlike the previous heat wave in early August which caused an intense peak on one day in the north, this week will probably be marked by two peak days. The northwest, like Brittany and Normandy, had been spared by the previous heat wave, but these areas should be affected this week by temperatures can reach 35°C.

To date, forecasts of Meteo France foresee a change from Sunday (which remains to be confirmed) with the return of thunderstorms and rain. The two days of August 14 and 15 could therefore mark the end of this heat wave if the forecasts are confirmed. The duration of this generalized heat wave will in this case be around 5 days.

New heat wave in sight for France until August 15!

While the third heat wave of the year is still underway in the south-east of France, temperatures will rise again next week. A fourth heat wave is now possible in France.

The peak intensity of the 3^e heat wave of the year was reached on Wednesday August 3 and Thursday August 4, with values ​​above 40°C in the southwest and southeast. This Friday, a clear cooling took place in the west and north of the country, but the high temperatures still resist in the departments bordering the Mediterranean, the Rhône valley and the Alpine valleys up to 38 ° C. No break in this heat wave is envisaged for the south-east, and a new heat peak will even occur this Saturday in these departments.

A risk of a heat wave between August 10 and 15

After a weekend below seasonal averages in the north, temperatures will gradually rise again at the start of next week. A powerful anticyclone will, once again, go further north than usualat the level of the British Isles and this will once again trap warm air over our country.

The situation weather report is quite reliable between Monday and Thursday: temperatures will exceed 30°C in the north, and 35°C in the south, and will locally reach 40°C. At this time, many uncertainties remain regarding the intensity and duration of this new heat wave: the official heat wave thresholds may be reached in the middle and end of the week between August 10 and 15. The temperatures are not expected to be as extreme as in July, but this new episode presents the risk of being lasting.

In 2017, the country had already had to face four heat waves between June and August. If this 4^e heat wave is confirmed next week, the event would therefore not be unprecedented, but still exceptional.

New heat dome over France affected by an interminable drought

A new heat wave is setting up this week: it is the third in three months, but it looks different from the previous ones.

The presence of a anticyclone over the Atlantic is setting up a south-westerly flow over the country: scorching air is once again coming up from North Africa and remains trapped over France throughout the week. This dome of heat is at the origin of a new heat wave, after that of July and that of June. This rise of hot air concerns this Monday the Pyrénées-Orientales, Gard, Vaucluse, Ardèche and Drôme, and will then extend tomorrow to the south-west.

This Monday and Tuesday, temperatures will locally reach 39°C in the Gard, and 36 to 38°C in the rest of the southern half. These high temperatures will spread from the southwest to the Loire this Wednesday and Thursday, the two hottest days of this episode, with more than 35°C and even locally 40°C in the southwest.

The heat peak in the southeast will take place between Monday and Tuesday, but nationwide, Wednesday is expected to be the hottest day. Thursday and Friday, the scorching temperatures will reach the northeast, with possibly 38 to 40 ° C in the city of Strasbourg. If current forecasts are confirmed, this heatwave will end over the weekend, but once again temperatures will remain high (over 30°C) over much of the country.

A less intense and shorter heat wave in anticipation

This 3^e heat wave will be different from the two previous ones by its intensity and its duration: the temperatures will a priori be a little lower (40°C and not 43°C as in June) and its shorter duration (5 days of heat wave against 15 in July). The June heat wave was exceptional due to its earliness and extreme temperatures. The july heat wave was also remarkable for its record temperatures, but especially for its duration in the southeast. The situation is currently different: France is affected by a south-westerly flow (and not due south as in July), which spares the north-west and Brittany from high temperatures in early August, unlike July.

Endless heat and dryness

The fact that France suffered a third heat wave is exceptional, but not completely unprecedented either: in 2017, the country had to face four heat waves between June and August. The novel side of this summer 2022 lies more in the duration of this heat and the drought that accompanies it: July 2022 is a priori the hottest and driest month of July ever recorded in France since the start of the Météo France readings.

What is particularly striking is that there is no real break in the heat in the south: even when the heat wave alerts are over, the temperatures remain high, and this, since the beginning of June! The same scenario should repeat itself in August: after this 3^e heat wave, there is no reliable signal from 4^e heat wave in sight (to date) but the heat should still be maintained with 30 to 35 ° C in the south the first 15 days of the month.

Return of high heat in early August with a third wave

After a lull of a few days, a new heat wave is looming for next week. It will be the third of the year and the 48^e since 1947! Towards a summer of all records in France.

The heat has settled in continuously in France and part of Europe since May and seems to no longer want to leave the region. This mid-week is marked by an appreciable break in temperatures, both in the north and in the south. The drop is less obvious in the southeast: the departments in this area are just 1 to 2°C below the heat wave thresholds for 2 to 3 days, and the feeling therefore remains very hot.

A heat wave every month since June

A new anticyclonic blockage, a priori lasting, will set in place this weekend and temperatures will start to rise again. They will reach 35 to 37°C around the Mediterranean, more than 30°C in the southwest, and 26 to 30°C in the north. Meteo France specifies that a signal of a new heat wave seems to appear from the beginning of next week: it is still too early to be precise concerning the intensity of the heat and its duration, but temperatures again outside the norm are already envisaged for the South-East. If the event is confirmed, it would therefore be a third heat wave (or even a heat wave) in three months: after that of june, July’sthe month of August could also be marked by a period of exceptional heat, a rare and exceptional situation since the beginning of the weather records.
