Weather: will it be very cold in December? The first trends revealed – Weather




After a relatively mild weekend, the thermometer will drop for the first days of December, despite still some uncertainties. But “the cold seems finally decided to arrive”, notes Cyril Bonnefoy, meteorologist from La Chaîne Météo. In question, “a powerful anticyclone [qui] will settle in the second half of the week from Russia to the Scandinavian countries”. With a swinging flow to the east, dry and cold air will reach the country. Coastal temperatures, they should be slightly below normal for the season, “with a winter feeling, reinforced by the east wind”.

In Brittany, temperatures will drop and drop below seasonal norms for the first days of December. Frosts will be more and more frequent? explains Stéven Tual, forecaster at Météo Bretagne. “We cannot exclude a more intense cold thereafter”. According to forecasts, temperatures will be between 5°C in the morning and 9°C in the afternoon, before continuing to drop from December 4 (3°C on average in the morning, 7°C in the afternoon). midday).

And then ?

From December 5, the cold could intensify throughout France. “A few depressions could come to deepen in the Mediterranean, on the edge of the very extensive anticyclone on the European continent”, explains La Chaîne Météo. “Temperatures should drop a notch further to be around -2°C below seasonal norms”.

A scenario to qualify, because “these projections remain largely to be confirmed”, warns Guillaume Séchet, meteorologist of Météo-Villes. “There are still significant differences on the extent of the cooling in France. The median scenario envisages for the moment a cooling of a classic order for the season, ”says one on the site of Météo-Villes. “There is currently no question of a cold snap”.

An already record month of November

A few days before the end of the month, November is already the tenth of the year with excess temperatures: +2.2°C above seasonal norms, on average. “It is now almost a given that 2022 will be the hottest (year) in France since at least 1930,” says Serge Zaka, meteorologist. Only January (-0.5°C) was colder than usual.

To return to the level of the current warmest year (2020), it would take an extremely cold month of December (-5°C below normal). An “almost zero” probability, according to Christophe Cassou, climatologist and research director at the CNRS.
