September 1, 2024 is the warmest on record, with the temperature reaching 31.5° in Maastricht by 4 pm. The previous top temperature dates from 1926 and was also set in Maastricht, weather bureau Weeronline said.

The temperature also reached a record 28.5° at the De Bilt weather station near Utrecht where official meteorological records are set. That is 0.1° warmer than the previous top temperature, which was also sent in 1926, Weeronline said.

The last time it was “summer” in terms of temperature – or at least 25° – on September 1 was in 1991.

“Tropical” temperatures of over 30° are not forecast to return this month, but it will stay warm for the time of year, reaching 25° inland on Monday and up to 29° in the far east. But the warmth will be driven away by thunderstorms as the day progresses, Weeronline said.

Sunday is the sixth official weather record set so far this year. January 23, February 15, March 3, March 14 and April 6 were all the warmest on record, but there were no new records set for chilly weather.

Last year there were seven warm and one cold record and the picture was similar in 2022 and 2021. In 2020, there were no cold records but no fewer than 14 for record high temperatures.
