Netherlands and Belgium issue orange heat alerts as temperatures near 40 °C

The Netherlands and Belgium have activated an orange heat alert as daytime temperatures climb toward 40 °C in several regions, with parts of Belgium issuing a red alert. The National Heat Plan, overseen by the RIVM, calls for extra water intake, reduced outdoor activity during peak heat, and the use of cooling shelters. Municipalities such as Utrecht and Arnhem have opened “cool spots” – libraries, churches and shaded public areas – and are urging vulnerable groups, including the elderly, children and chronically ill, to stay hydrated and avoid exertion. Smog warnings accompany the heat, prompting health agencies to advise people to stay indoors when possible. Public events across the country, from markets in Deurne to sports competitions, have been postponed or shortened, and schools have introduced “tropical timetables” to avoid indoor activities during the hottest hours. Police and fire services are implementing heat‑specific safety protocols, and electricity markets have seen record‑high prices as demand for cooling spikes. Health officials stress the risk of dehydration, heat‑related illness and increased mortality, especially among home‑bound seniors, and urge residents to check on neighbours. The coordinated response aims to mitigate the health and economic impacts of the unprecedented heat wave.
