Overview
- The heat plan was reactivated on Saturday, July 11 after KNMI forecasts met the rule of four consecutive days with maximum temperatures of at least 27°C.
- Forecasters expect a weekend average near 29°C with inland and southern highs locally reaching about 32–33°C over the coming days.
- Meteorologists say the episode will be drier than late June and that nights should mostly fall below 20°C, reducing the risk of prolonged oppressive conditions.
- RIVM and municipalities have published daily guidance to drink more fluids, keep spaces cool, check on elderly and chronically ill people, and some local cooling sites such as Museum Vlaardingen have opened.
- The plan targets protection of older people, young children, the chronically ill, the socially isolated and homeless after an earlier late‑June heat wave that was linked to elevated mortality estimates by the RIVM.
