The heat is settling in France and certain regions will be very close to heat waves. Météo France does not, for the time being, issue any particular alert, but vigilance is nonetheless essential, particularly for the frail.
What will distinguish the next few days from a real heat wave is the duration of the event. It will be relatively brief. However, for a heat wave to exist according to the criteria in force, it takes a certain number of days and nights when the thresholds are exceeded. These thresholds, which vary depending on the region (they are higher in Marseille than in Lille, for example) will be crossed, but not over time. It is therefore rather a heat peak, from a meteorological point of view, because of its duration, spread between the first hours of Wednesday and the night of Friday to Saturday.
The weather channel, a competitor of Météo France, however issues an alert for the regions of Paris and its inner suburbs as well as for Lyon and the Rhône department. “The nights will sometimes remain tropical (20 ° C to 22 ° C) and the hot days (33 ° C to 35 ° C). "
🟡 Heat wave alert. The # Rhône as well as #Paris and its little crown are placed on #carbon alert by our services. We will indeed be at the limit of the heat wave thresholds in these departments these next three days, before the arrival of thunderstorms. 🥵 https://t.co/FLNSZUjpkC pic.twitter.com/8DrHa3Biw0
- The Weather Channel (@lachainemeteo) June 23, 2020The night of Tuesday to Wednesday will be the first where temperatures will struggle to drop below 20 ° C in these cities. This low point will also be reached at the end of the night. Wednesday, "the heat waves will be exceeded in Paris with 33 ° C and in Lyon with 35 ° C". In the night from Wednesday to Thursday it will be between 21 ° C and 23 ° C at the lowest.
23 ° C at the coolest time of the night from Thursday to Friday
On Thursday, the thermometer gains another degree with 34 ° C expected in Paris and 35 ° C in Lyon. The night from Thursday to Friday will be the hottest of the week with a minimum of 23 ° C, again at the end of the night only. Knowing that it is advisable to sleep in a room below 20 ° C to facilitate sleep and recovery, the night promises to be difficult for the most sensitive and fragile.
Thunderstorms could drop temperatures in Paris on Friday. This will not be the case in Lyon where the 35 ° C mark should be reached before another night at more than 20 ° C.
