"July 2021 will be remembered as one of the windiest and driest July," comments Météo France. “The lack of cyclonic input in precipitation is one of the main causes of water scarcity. The month was sunny on all the islands and hot on the northern islands, ”he explains.
The month thus ranks as the fifth hottest July since 1959. The daily extrema were mostly hot throughout the month, sometimes up to 2 ° C higher than the expected value for a maximum or up to 1,5 ° C for a minimum, Météo France note. The average temperature was 29 ° C against 27,9 ° C in June.
Regarding the winds, the trade winds were maintained from the northeast and most often moderate to fairly strong with gusts under the few rainy episodes, outside Elsa's passage.
Regarding rainfall, if the normal ratio had shown an excess of precipitation in Saint-Martin of the order of 45 to 50% in June mainly due to almost daily rains, the month of July experienced deficits ranging from 20 to 30% in Saint-Martin and 40 to 50% in Saint-Barthélemy. July ranks among one-third of the dry July months of the past 60 years in the Northern Islands.
