Too hot or even too hot

As in May and June, the thermometer is very often brought to the month of July 2022.

The national monthly average temperature rises to 22.6 degrees, or 2.1 degrees above normal in 1991-2020. July 2022 rose to third position among the warmest Julys since 1946, behind 2006, which was warmer with 23.6 degrees, and 1983, almost warmer with 22.7 degrees.

July 1st is cool. That morning the national minimum was reached with only 5.9 degrees in Angers. In the second network, a value of only 3.4 degrees was measured that same day in Ploerdut, in Morbihan.

As for the heat record for the month, it was 42.6 degrees at Biscarrosse, in the Landes, on the 18th. That same day, it reached 42.7 degrees in Beaulieu-sur-Layon, in Maine- et Loire. The values ​​are too high, which however remain lower than in July 2019 at the national level.

It should be noted that during the period January-July, 2022 establishes a new record for warmest first seven months of the year with an average of 13.51 degrees, beating the 13.43 degrees of the same period in 2020! The normal (1991-2020) is 12.21 degrees, or 1.2 degrees above.

Almost no rain

L’absence of disturbance worthy of the name and the very rare storms brought no water to French soil in July. The drought reached a extreme leveldid not reach this month of the year.

In fact, only 8 mm of rain fell on the national average in the month of July for the normal 50 mm. The deficit therefore reached 84% ! This figure exceeds 12 mm from the recent record in July 2020. This lack of water, combined with high temperatures and rare sunshine, is causing remarkable surface drought, despite of stormy and well watered (72 mm for a par of 55 mm ).

These 8 mm correspond to the third lowest accumulation for all months combined, behind the 6 mm of March 1961, the 7 mm of April 1955 and therefore third tied with March 1953.

Many stations remained at 0 for this month of July around the Mediterranean, but also in the Loire department, in the Haute-Garonne and in the Landes.

In the main network, the maximum is very low with only 38 mm in Chamonix (Haute-Savoie) followed by 36 mm in Luxeuil (Haute-Saône) and 33 mm in Limoges. With the secondary weather stations, the maximum goes to Fontannes, in Haute-Loire, with a figure of 118 mm, almost double the normal in this town… but in only two storms: 43 mm on the 4 and 73 mm on the 18th. Remaining 2 mm from morning dew or rare drops.

The 262 mm of rain measured from January 1 to July 31 still does not set a record in France, although we have to go back to 1976 to find at least as little with 253 mm. This is the year 1949 held the record for the driest year with only 238 mm in the same period, since 1946. The drought of 1921 was however more severe (only 115 mm in Paris from January 1 to July 31). As water demand has increased dramatically since under demographic pressure and water-starved agriculture, the 2022 drought remains very difficult.

Record sunlight

The clouds are very cautious in this month of July 2022. Thus, the national average sunshine reaches an impressive number of 351 hours, or almost 12 hours of sunshine per day and almost 100 hours more than normal (+37 %)!

Of course, this very high number sets a new record, clearly beating the 340 hours of July 1949.

In Brest the sun shines for at least 243 hours the same. The island of Levant, in Var, holds the national monthly maximum with 421 hours of sun presence, almost 14 hours a day!

A very busy month of July: very dry record low rainfall, too much sun The high and particularly warm record was beaten, although lower than in 1983 and especially in 2006. The drought is in full swing, on the surface and in depth, while the crops and crops need it most at this time of the year. ‘ years. Finally, a word on another disastrous consequence: forest fires in the four corners of France, exacerbated by specific weather conditions, although they are for the most part of human origin, accidental or intentional. ..
