What you need to know
The count combines the hottest reporting place each day: Limburg may supply one date and the east another. It signals a long season of heat exposure but cannot describe a particular bedroom, workplace or medicine. Warm nights, top-floor housing and living alone often determine health risk better than one national maximum. KNMI defines a tropical day as 30°C or more and an extremely hot day as 35°C or more. The record is climate context; today’s action still depends on live warnings and RIVM advice, not a historical number treated as a forecast. Hokimi turns the headline into a home audit: when shading closes, who needs a check-in and whether medicines or food storage are heat sensitive.
- Thirty-one means at least one Dutch station reached 30°C.
- It does not mean every location had 31 tropical days.
- KNMI separately defines extremely hot days at 35°C or more.
- Live decisions should follow KNMI and RIVM.
Hokimi field note：Note the bedroom temperature tonight, plan water and neighbour contact, and never leave children, older people or animals in a hot vehicle. Information last checked on 13 August 2026：source1 · source2 · source3。
