Overview
- On Friday several KNMI-monitored sites reported mid-30s Celsius with Westdorpe at 34.8°C and Gilze-Rijen at 34.4°C while De Bilt recorded a very high reading that Weeronline put at 35.2°C.
- Weerplaza and regional forecasters warned of temperatures that could approach the high 30s before the peak readings were recorded.
- The RIVM issued ozone (smog) warnings for parts of Groningen because high heat raised ground-level ozone to 'insufficient' air-quality levels around mid-afternoon.
- Provincial authorities limited operation of the Robbengatsluis at Lauwersoog to protect freshwater supplies and local municipalities adjusted services such as shortened waste-station hours in Winschoten.
- Forecasters say a wind shift to the north/northwest will cool most areas to the low-to-mid 20s by Sunday and raise the chance of isolated showers or thunderstorms next week, and Friday's warm-date record was the eleventh such date-record this year.
