With temperatures at the Royal Meteorological Institute’s Ukkel (Brussels) weather centre topping 18.9°C at around 2pm, 25 February 2026 became the warmest 25 February in Belgium since records began.
It was a tweet from the KMI meteorologist David Dehenauw that confirmed that this Wedenesday will go down in the record book. David Dehenauw says that it is likely to get (a little) warmer before the end of the afternoon. The last top temperature record for 25 February was set 7 years ago in 2019 when temperatures at KMI’s Ukkel HQ reached 18.8°C.
David Dehenauw broke the news that a new temperature record had been set in a post on the social media platform X.
Meanwhile, KMI’s reports that temperatures of 19°C have been recorded at some locations. David Dehenauw says that it won’t be until the evening that we will know what the new temperature record for 25 February is.
It will cool off somewhat during the evening a night with temperatures expected to fall to between 4°C and 10°C.
