• The cumulative rainfall for the month of May in Gironde is to date 106 mm, almost twice the normal.

  • The department had experienced just before, its third wettest winter since 1959.

  • The trend for the next few days is a rise in temperatures with a dominant sun, and in its seasonal forecast Météo Frange anticipates a next quarter "hotter and drier than normal."

    "

A winter from December to February among the rainiest since 1959. Then a month of May almost twice as rainy than normal… The Gironde has not been spared from bad weather in recent months, and as the month approaches in June, we have the feeling of coming out of a real rain tunnel.

Since the beginning of the month, "the depressions have continued to circulate over the Atlantic and rains have frequently watered the Gironde until 25 [May]", explains Mireille Alleno, from the study and climatology department of Météo France in Bordeaux.

“To date, it has fallen between 70 and 130 mm (116 mm at Bordeaux-Mérignac airport), which represents one and a half to two times the normal amount of rain in May and even up to 73% surplus for Bordeaux.

"

Twelve to 17 rainy days so far

Over the department, the cumulative amount is 106 mm, which ranks this month of May among the 12 wettest since 1959, far behind May 2020, for which the cumulative amount was 131 mm (the second wettest since 1959, after May 1984 with 139 mm). "But in May 2020, there were significantly fewer rainy days: between 8 and 11 days, against 12 to 17 this year," said the meteorologist. The average for a month of May is 10 or 11 days.

On the temperature front, the situation is not much better, despite May 8 when we reached between 28 ° C and 30 ° C.

To date, the monthly average temperature for the month of May in the Gironde is 13.5 ° C instead of 15.4 ° C normally, and 13.7 ° C in Bordeaux instead of 15.7 ° C .

But the rise in the thermometer announced for the last four days of the month should allow May 2021 to end with averages closer to normal.

30 ° C next week?

This rainy month of May therefore arose after a particularly rainy winter (from December 2020 to February 2021), since it was the third wettest winter since 1959. The Gironde was however spared by the rains during the March period. -April, which is the second driest since 1959 in the department, after that of 1997. “After this very rainy winter, we had the impression in May of not getting out of the rain, comments Mireille Alleno. mid-February to the end of April we didn't have much water. Farmers at that time were also worried about very dry soils. "

On the other hand today, these same farmers also implore the return of the beautiful days, the plants having again need of heat to grow… This is good since the forecasts for the next days indicate temperatures which should oscillate between 20 ° C Saturday and 25 ° C on Sunday.

They could even climb locally to 30 ° C next week, with a dominant sun.

In addition to this, you need to know more about it.

In its seasonal forecasts, Météo France anticipates a next quarter (from June to August) “hotter and drier than normal.

But these model-based predictions have their limitations, and vary widely from place to place.

Without planning so far, we should in any case be able to take full advantage of the terraces which have just reopened in the coming days.

It's already that.
