Paris is finally experiencing its first day of heat. Several meteorologists announced that the capital had, with several days of delay, exceeded Saturday the bar of 25 ° C "for the 1st time of the year," writes François Jobard, of Météo France. It was finally measured at 25.5 ° C at Parc Montsouris.
"This is the 1st day of heat this year in the capital, which is late compared to previous years," also notes the Weather Channel.
#CHALEUR: 25.1°C recorded at #Paris just now! This is the 1st hot day this year in the capital, which is late compared to previous years. You have to go back to May 27, 1999 to find a first day of heat so late in the year in Paris... pic.twitter.com/w3hw3hg26r

François Jobard specifies that it is necessary to go back to 1999 to have a day of heat so late in the capital, the thermometer had exceeded 25 degrees on May 27 also.
But this is not a record. In 1983, the first day of heat was measured on May 31 and "the latest ever observed since measurements began in 1873 was on June 26, in 1972," notes the meteorologist.
A "grey and rainy" early spring
This delay is due to disturbed weather in recent weeks, "after 32 days without significant rain at the end of winter, spring appears gray and rainy," wrote Météo France mid-May. The organization then noted that in Paris "since 01/01/2023, 20 ° C have been reached or exceeded only 8 times, against 29 times in 2022".
The month of May is very different from that of the year 2022, during which many heat records, with temperatures exceeding 30 degrees, were broken.
But faced with this cooling, meteorologists recall that global warming remains present, and that France continues to break records of heat days in recent years: 98 days were measured in 2018, a record since measurements began. In second place we find the year 2022 with 88 days.
But the trend is heavy: the number of hot days increases significantly in Paris, as elsewhere...

According to current forecasts, the weather should remain sunny over the capital in the coming days, with, before the passage in June, other passages above the 25 degree mark.
