Belgium activates its alert plan in response to heatwave and ozone pollution
The Risk Management Group (RMG) officially activated the alert phase of the Ozone and Extreme Heat Plan on June 23, 2026. This decision comes as temperatures are rising rapidly across Belgian territory, posing risks to public health.
The rise in temperatures, combined with a high concentration of ozone in the air, can cause respiratory problems and irritation in the most vulnerable individuals. Health authorities are therefore calling for vigilance, particularly regarding young children, the elderly, and those suffering from chronic illnesses.
As part of this plan, it is advised to limit intense physical exertion during the hottest hours of the day, specifically between noon and 8:00 PM. It is also recommended to drink water regularly, stay in cool places, and keep homes shielded from the sun by closing curtains or shutters.
The Belgian government will continue to monitor the meteorological situation and air quality over the coming days. Citizens are invited to follow the official recommendations issued by local authorities and to stay informed via standard communication channels regarding the evolution of this alert.
