A “heat dome” will settle on our country: here is what to expect in terms of temperatures that will break records

A phenomenon which could however very well occur in Belgium, this summer, given the heat announced. Similarly, “”It is a complex cocktail: it takes humidity, heat, a disturbance at altitude, instability. Similarly, But no, there is no clear increase in the number of storm days since the 1960s. Nevertheless, On the other hand. However, there is a significant increase in the days with at least 20 liters of rain per square meter. Similarly, It may be due to summer thunderstorms, but not only“, He analyzes.

A meteorologist warns in front of the “abnormal” temperatures of the next few weeks: “This type of configuration is worse than a heat wave”

A heat peak that “heat dome” will settle our new will arrive very quickly – &quot. heat dome" will settle our

But what worries Belgium for the next few days is the new -. For example, big – “heat dome” will settle our heat peak that will arrive very quickly. However, This time, we are talking about a heat dome that will affect a good part of Europe. For example, “”The situation will gradually stop. Therefore, We will find more anticyclonic conditions, with temperatures increasing every day. Therefore, From this Friday, it will climb. Saturday, we could reach 30 ° C locally, and Sunday even more Sunday. Beginning of next week. we are waiting for the installation of a heat dome on Monday. Tuesday, even until Wednesday and later in the week, depending on the model. We are considering temperatures that can reach, or even exceed, 35 ° C. Additionally, We enter another configuration, in fact. To locate: “heat dome” will settle our new in Uccle, since 1892, we only had 12 days at 35 ° C, including 8 since 2018. Monday and/or Tuesday, we could therefore live at least a 13th day at this threshold.“

Values ​​that will certainly take us to a first official heat wave in 2025. “Yes, it is clearly possible. For a heat wave, it takes five consecutive days at least 25 ° C including at least three at 30 ° C. There, Saturday, Sunday, Monday, Tuesday … it seems likely. More than 50 % chance, in my opinion. And in terms of warnings, there is an orange threshold from 35 ° C, which could be reached“He says.

Strong heat in Belgium: “We will know an exceptional sequence”

A dangerous summer

In any case. Belgium is preparing for a dangerous summer, and the first measures are taken. First. the warning phase of the “hot weather. ozone peaks” plan “heat dome” will settle our new has come into force since Wednesday, said the Interregional Environment cell (Celine). This phase is activated when the sum of the differences between the maximum temperatures for the next five “heat. dome” will settle our days. the threshold of 25 ° C is greater than 17 ° C. Ozone concentrations will increase from Saturday, but no exceeding from the European information threshold is currently planned. A bulletin specific to the situation for ozone will be disseminated according to the evolution of the concentrations. specifies the interregional cell.

For their part. the Walloon. Brussels municipalities are working in order for their heat plan, with water distribution programs, or even spontaneous visits to the most vulnerable people, especially isolated elderly people.

Regarding drought. the news is a little more reassuring. but the situation could quickly become tense, especially in the west of the country. Furthermore, The only news “heat dome” will settle our new (very) positive is that the rain records that have accumulated between October 2023. February 2025 made it possible to fully fill the water tables, which therefore remain at very good levels.
