A new heatwave hits Belgium: what you need to know
Belgium is currently going through a period of high temperatures, as confirmed by meteorological services. David Dehenauw, the renowned meteorologist, has officially classified this episode as the "second heatwave" of the summer of 2026. Temperatures are rising across the entire country, forcing authorities to reiterate standard safety precautions.
This climatic phenomenon is characterized by temperatures exceeding usual thresholds for several consecutive days. In many Belgian regions, the mercury is showing high values, both during the day and at night, which limits the natural cooling of homes. Urban areas, in particular, are intensely feeling this heat island effect.
Faced with these conditions, experts recommend remaining vigilant, especially for the most vulnerable people such as children and seniors. It is advised to drink water regularly, close shutters during the day to keep the interior cool, and avoid intense physical exertion during the hottest hours of the day.
According to the latest forecasts, this heatwave should, however, come to an end soon. Weather services are announcing a gradual drop in temperatures in the coming days, accompanied by a return to conditions more in line with seasonal norms. Belgians can therefore expect a welcome relief before the end of the week.
