The yoyo weather, do you like it? It is better: after a grey and chilly month, a weekend beautiful and warm. After the first half of June cold and wet, here comes a heat spike, Tuesday 18th June, with temperatures above 30 ° C over a large part of France. Would it be summer, finally? Not quite.
It’s a peak, it’s a cape – not a peninsula. Even less a wave. No heat, so. Just a spike of heat. You tell me, by the times, it’s already not bad. And it will not hurt. It is true. But the transition is likely to be brutal. Imagine: this Friday 14th June, in Rennes, it is 18 ° C; next Tuesday, the temperatures will climb to 28 °. And this episode brutal and ephemeral will affect the whole of France (infographic below).
Or almost: only Corsica is an exception. This Friday, due to a powerful local weather phenomenon – the sirocco – thermometers graze 40 ° C on the west coast of the island. But in the middle of next week, while the whole country will suffocate, they will struggle to compete with their continental counterparts.
Peak heat, temperatures exceeding 30 ° C: would it be summer, finally, after a month of May disappointing and a first half of June cold and wet? Not that easy. Let’s see the evolution of the expected time of this weekend until next Friday.
A nice weekend, but sometimes mixed
Between Friday and Saturday, the temperatures find – finally – seasonal values. But the weather remains stormy and cloudy over a large part of the country.
Sunday announces Meteo France, the risk of showers decreases to be limited to the regions close to Manche. The sun will shine brightly over the rest of the country and temperatures will begin to climb: 27 ° C on average on the South, 22-24 ° C on the North.
A Monday under the sign of the sun and the heat
“Monday in the sun is something we will never have , ” said Claude François. And this will indeed be the case for us on Monday 17th June: the good weather, hot and sunny, will affect the whole of France.
From Monday morning, it will be between 17 and 25 degrees, although some clouds will still be present in the north, before reaching the south in the afternoon.
The temperature rise will increase: 27 ° C in the northern half, 30 ° C in the southern half, with peaks at 32 ° C or 35-36 ° C locally.
Maximum heat Tuesday and Wednesday
The rise in temperatures will continue in anticyclonic conditions to reach the famous peak on Tuesday (map at the head of the article) and Wednesday (map below).
Look at the map below , which shows the isobaric situation expected Tuesday in the middle of the day, but which will remain valid for Wednesday: a very shallow depression (1000 hPa) in the west of France, an anticyclone (1023 hPa) ) in the north-east, two weak anticyclones (1,019 hPa) over Switzerland and Italy, and a huge barometer swamp above our country. Result: Nearly zero wind in the east, very weak flow from the south, southeast to the east all over the west. In other words, little ventilation.
Tuesday and Wednesday will, therefore, be the hottest days (Meteo France infographic above). The 30 ° C will be reached or exceeded in the north of the country, with 30 ° C in Paris and 32 ° C in Strasbourg, and up to 33 ° C (Toulouse) and 35 ° C (Carpentras) in the South.
In Brittany, Normandy, Pays de la Loire and the Hauts-de-France, the situation will be a little less stifling. But the peaks will reach 27 to 28 ° C.
Note that high temperatures are not necessarily synonymous with good weather. Tuesday will see some clouds still lingering, especially on the West.
Return of seasonal temperatures at the end of next week
It has been said, this peak is not a wave. No persistent heat, so. Because a slightly degraded time is expected in the second half of the week.
Meteo France announces indeed a return to the normal for the season as of Thursday (map below). And the arrival of a mass of fresh air from the northwest, which will bring clouds and some stormy rains. Temperatures will therefore hardly exceed 20 ° C north.
Suffice to say that on Friday, June 21, the weather will be just in tune with the day of the calendar summer and the Music Festival.
