“The only good news is that the days are already a little shorter, which offers a night respite. But the nights will sometimes remain suffocating, with 20 to 21 ° C in the city centers.“
Regarding a possible official heat wave, “I would say it’s 50-50. It will depend on Thursday, when the 30 degrees are not insured“.
What should we expect at the temperature level in Belgium?
And for the future? “”Until August 20-25, we will remain above seasonal normal. In the best of cases, slightly above; in the worst, well above. If we integrate forecasts until the end of August, we could reach a summer average around 19.7-19.8 ° C. The record is 19.85 ° C in 2018. So we are likely to finish in the top 3, and almost certainly in the top 5 hot summers since 1833“, he specifies.
He also took the opportunity to take stock of a few mixed weeks from the end of July. “Some have found the summer ‘rotten’ because of two weeks mixed at the end of July, in early August, but that is not enough to establish a balance sheet. Over three months, the observation is clear: it is a very hot summer, as the seasonal trends had planned.”
Will extreme temperatures announced in France: will Belgium also be affected by this heat wave?
Belgium affected by a heat wave?
For his part, Xavier Fettweis indicates that a new heat wave could quickly take over, next week. “”It is possible for a second heat wave to occur after next weekend. If these waves occur on very dry soils, as is the case in France, temperatures could be even higher“He says.
This is enough to imagine a return of the classes and an early fall under the sun, therefore. “”The first scenarios still show temperature anomalies above 1 ° C for September. The heat could therefore be prolonged. Until August 23-24, no sustainable degradation signal appears: the weather will remain globally sunny, dry and hot, even very hot“Concludes Pascal Mortmal.
