Overview
- KNMI issued a double code geel because daytime temperatures have risen above 33°C and thunderstorms are forecast for the afternoon and evening, triggering citywide weather warnings.
- Primary schools have activated tropenroosters, shortening the school day or offering cool indoor activities while also informing parents and providing supervision for children who cannot be picked up.
- Some schools reported broken air conditioning units, which contributed to early dismissals and forced families to arrange alternative care or supervision.
- Outdoor workers such as painters are changing routines by shifting to morning hours, stopping earlier, wearing protective clothing, using sunscreen, and drinking extra water to avoid heat-related illness.
- Health agencies KNMI and RIVM warn against heavy physical exertion during the episode because children may not self-regulate heat exposure and vulnerable people face higher risk of dehydration and overheating, with further disruption possible if storms arrive.
