“At 3.20 p.m. in Uccle 26.5°C. First summer day of 2020,” weatherman Frank Deboosere reported on Twitter. According to the RMI, it is officially a summer day when temperatures in Uccle exceed 25 degrees Celsius.
Last year the first summer day fell almost a month earlier: on April 22nd. And in 1939 temperatures rose above 25 degrees as early as 11 April.
