Heatwave July 2022 alert for Monday what is the weather

HEAT WAVE. Short respite in the northern half of France this Friday and this weekend as temperatures will rise further in the south. It will be worse at the start of the week with temperatures close to record highs on Monday and Tuesday. We take stock of the latest weather forecasts and advice to follow.

The essential

  • The weekend of July 16 and 17 promises to be hot over a large part of France. Already, this Friday, July 15, the maximum temperatures will exceed 35 degrees in Occitania with 37 degrees expected in Perpignan. 33 degrees are expected in Lyon and Bordeaux, 34 in Marseille while the Parisians will blow a little with 26 degrees expected.
  • The situation will be broadly similar on Saturday with high temperatures in the southern half (up to 36 degrees). On Sunday, 30 degrees will again be reached in the north before two scorching days of Monday and Tuesday. We expect up to 37 degrees in Paris.
  • Temperatures should still be very high on Monday and Tuesday before a gradual return to normal, not before Wednesday in the west with the arrival of thunderstorms and at the end of the week in the east of the country.

Questions answers

What advice should be followed to take care of a baby during a heat wave?

In times of heat wave, concern wins over many young parents. Babies are indeed fragile people in times of heat wave since their body does not yet have all the faculties to regulate its temperature and cope with these heat waves. The first danger is obviously dehydration which will be marked by weight loss or a lack of energy and visible interaction. More rare and spaced urine is also a sign to take into consideration. “For bottle-fed children, we recommend offering water between the bottles of milk, which we continue to give at the usual rate”, explains pediatrician Alicia Pillot on Thursday, interviewed by France Info in June. For breastfed infants, there is no need to offer additional water provided that “feedings on demand” are respected. On the other hand, the mother must closely monitor her hydration.

And in Brittany, what temperature peak this Friday?

It will be less hot in Brittany this Friday July 15 but the 30 degrees will still be close to 29 degrees expected in Quimper, Rennes or even Redon against 28 degrees in Lorient, 26 degrees in Brest and Morlaix and 24 degrees in Saint-Malo .

But by the way, when can we talk about a heat wave?

To speak of a heat wave, the temperatures must be five degrees higher than normal for the season, day and night, and this for at least three days and three nights. The heat wave temperature threshold therefore differs according to the departments and regions. Heat waves most often occur in France in July and August. We must be vigilant from the month of June. High temperatures, even above seasonal norms, do not necessarily mean a heat wave. Most often, these are heat waves.

In the Grand Est, short lull this Friday?

In the Grand Est region, we are preparing for a heat wave at the start of next week with 36 to 37 degrees expected in Lorraine and Alsace in particular. This Friday, the temperatures will be much more pleasant with a maximum of 28 degrees in Mulhouse and 27 degrees in Strasbourg, Epinal or Lunéville. We expect 26 degrees “only” in Metz and Nancy and 25 degrees in Reims.

What maximum temperatures in Auvergne-Rhône-Alpes this Friday?

26 degrees is the temperature expected this morning in Lyon and in several places in the Auvergne-Rhône-Alpes region. The temperatures will soar this afternoon since we expect 35 degrees in the Drôme and the Ardèche but also 33 degrees in Lyon, Grenoble, Chambéry or Moûtiers, 31 degrees in Mâcon or Bourg en Bresse, 32 in Annecy, 30 degrees in Aurillac and Saint-Etienne against 28 degrees in Clermont-Ferrand.

What temperatures in PACA this Friday, July 15?

It will already be 27 degrees this morning in Marseille where we expect 34 degrees at the height of the day. This Friday, July 15 promises to be scorching in the Bouches-du-Rhône where Météo-France expects up to 38 degrees in Istres and 37 degrees in Aix-en-Provence. In the Var, we expect up to 36 degrees in Saint-Maximin La Sainte-Baume, 34 degrees in Draguignan, 30 degrees in Toulon. In the Vaucluse, it will be up to 37 degrees in Avignon and Carpentras. In the Alpes-Maritimes, count up to 34 degrees in the hinterland and 30 degrees by the sea like in Antibes.

The concern of caregivers at the Bordeaux University Hospital

“I think we are going to lose some patients. (…) We are heading towards disaster”, worries this Friday Agnès, nursing assistant at the Bordeaux University Hospital interviewed by France Info. Caregivers point out that the service is not air-conditioned and warn of the risk of dehydration for patients and a possible influx of patients.

What temperatures in New Aquitaine this Friday?

It will be hot again, very hot this Friday in the Nouvelle-Aquitaine region. 24 degrees are expected from the morning in Agen and the afternoon will be scorching with 35 degrees in Mont-de-Marsan, 34 degrees in Tulle and Agen, 33 degrees in Bordeaux, 32 degrees in Pau. By the sea, we also expect 29 degrees in Biarritz and 30 degrees in La Rochelle.

Where will it be hottest this Friday?

This Friday, the maximum temperatures expected will be between 20 degrees in Cherbourg and 40 degrees in Alès. Occitania will be particularly affected by the heat with 38 degrees in Nîmes, 37 degrees in Perpignan, Béziers or Carcassonne and 36 degrees in Montpellier.

Which departments are on heatwave orange vigilance this Friday?

Météo France should publish a new alert bulletin at 4 p.m. this Friday. For the time being, 11 departments have been on heat wave orange vigilance since Thursday: these are the departments of Gironde, Lot-et-Garonne, Tarn, Tarn-et-Garonne, Haute-Garonne, Pyrénées- Orientales, Gard, Ardèche, Drôme, Vaucluse and Alpes-de-Haute-Provence.

Météo France published its new heatwave vigilance map on Thursday. Are you concerned?

When will the heatwave end?

It is still difficult to define an end date for the coming heat wave, the forecasts being refined day by day. For the moment, Météo France announces a scorching weekend in a large part of the south, and Monday is likely to be very hot almost everywhere in France. Temperatures should then gradually drop from Wednesday July 20 when record temperatures will hit the East (36 to 37 degrees) before leaving the metropolis. The episode therefore promises to be long and grueling.

Heat wave, heat peak, heat wave and heat dome: what are the differences?

Heat wave and heat wave are two different things. To speak of a heat wave, temperatures must be 5 degrees higher than normal for the season, day and night, and this for at least 3 days and 3 nights. The heat wave temperature threshold therefore differs according to the departments and regions. Heat waves most often occur in France in July and August. We must be vigilant from the month of June. High temperatures, even above seasonal norms, do not necessarily mean a heat wave. Most often, these are heat waves.

The term heat peak is more to be used during a sudden rise in temperature, whereas a heat wave corresponds to a longer episode. Météo France judges that a heat wave is in progress when temperatures above the monthly average are detected by more than three degrees Celsius, for at least three days.
Last term often mentioned these days when talking about these scorching temperatures, that of a heat dome. A heat dome settled over almost the entire country this May 2022. This meteorological phenomenon is explained by a large mass of hot air from Morocco and Spain, trapped by atmospheric pressure. This usually occurs in summer, but also in spring. This results in scorching heat.

You should know that Météo-France provides several levels of heat wave vigilance: level 1 (green) corresponds to a “seasonal watch”, level 2 (yellow) to a “heat warning” and it is level 3 (orange) which corresponds to the “heat wave alert”. Finally, level 4 (red), the highest, determines “maximum mobilization”. In summer, it is not uncommon for several departments to be placed on orange or red alert for the heat wave.
