"Saint-Servais, Saint-Pancrace and Saint-Mamert make the three of them a little winter". Will the saying associated with the Ice Saints (May 11, 12 and 13) deliver on its promise this year? After a weekend of May 8 disrupted by thunderstorms but with temperatures above normal season, the second week of May promises to be cooler.
If the thermometer has easily exceeded 20 degrees throughout Île-de-France these last three days, the mercury will fall well below normal seasons from midweek. For example, France weather forecasts only 14 degrees in Paris for this Thursday, 8 degrees less than this Monday.
'No frosts to fear'
According to La Chaine Météo, the Ice Saints will be associated with "cool and unstable weather", with sleet in a northwesterly flow, in a cooler air mass than normal for the season, on the order of 2 to 4 ° C below average. This episode is primarily due to the passage of active precipitation on Tuesday with a very high risk of rain, which will give way to "polar air" which will plunge temperatures.
Should we then fear a last frost before the summer as the Ice Saints want? "There are no frosts to fear for May 11, 12 and 13," says Patrick Marlière of Agate Météo. The meteorologist prefers to evoke a "small refreshment", but with temperatures that "will remain seasonal" all the same.
The #Saints_de_glace period occurs from May 11 to 13. It is feared in agriculture because it corresponds to the last period of spring when it can freeze in the plain. However, the #fraîcheur will be there during this period. However, thanks to the presence of... pic.twitter.com/7neFwXTeUX

In addition, cloud cover and the multiplication of showers will, for once, be good news... at least for agriculture. Indeed, for the Ice Saints to be synonymous with frost, the sky must be clear, especially at night. To date, the cold polar air mass, very cool at altitude, should not have too much impact on our soils. On the other hand, we will have to take out the umbrellas!
