FactualIt’s not just an impression, the month of May was gloomy, contrasting with the period of confinement, in April, which was sunny, mild and dry.
Does the weather mock the confined French? The first confinement linked to the Covid-19 epidemic, from March to May 2020, had been particularly sunny and hot. The same was true for the last confinement, in April, followed by a cool and rather gloomy period, in May, when health constraints were relaxed.
With an average of 13.8 ° C, May is the coolest month recorded since 2013 on the mainland of France (we had then recorded an average of 12.8 ° C). This month was also very rainy, with a cumulative 107.7 mm of precipitation instead of 83.4 mm for the normal ones (1981-2010). This impression of seeing the rain falling constantly in May, especially in the north of France, was amplified by the contrast with the months of March and April with a deficit in precipitation, as measured by Météo-France.
Sun … and freshness
Over the whole of the meteorological spring (March, April and May), “The number of rainy days was lower than normal in most regions”, met Météo-France. The deficit “Exceeded 20% near the Channel coast” and in the regions bordering the Atlantic, “And often 50% along the Pyrenees”. On average, in France, rainfall is in deficit by more than 10%.
Generally speaking, this meteorological spring “Was marked by great freshness despite a remarkable peak of heat for the season” which occurred at the very end of March and at the beginning of April, says Météo-France.
Over the three months, from March to May, the sunshine reached 20% to 40% more than normal, particularly in the Northwest. On the other hand, this surplus was recorded above all in March and April, while the month of May – which coincided with the first deconfinement measures – was much less bright.
