From Saturday 15 August 2026 at 08:00 in the morning, the National Heatwave Plan will no longer be active in a large part of the country. On Saturday, the plan will only remain in effect in four provinces: Limburg, North Brabant, Gelderland and Overijssel, where a heat intensity of 7–8 is still expected. On Sunday morning at 08:00, the National Heatwave Plan will also be lifted in these four provinces. Naturally, the Royal Netherlands Meteorological Institute (KNMI) and RIVM will remain on the lookout for new periods of heat.

On Friday 14 August, air quality is expected to be “poor” in the central, eastern and northern parts of the Netherlands. This could cause discomfort for people who are sensitive to smog. RIVM advises them to stay indoors and limit strenuous physical activity. This advice is most relevant from early afternoon into the evening, when the air will be most polluted.
