Overview
- Parts of the country reached 20 to 21°C on Wednesday in bright sunshine with a light to moderate easterly wind, marking the year’s first 20-degree day.
- Forecasts point to an even warmer Thursday in some areas, locally up to about 23°C, before cloud builds and evening showers arrive with the front.
- Cooler air follows on Friday with highs near 13°C under a northerly to northwesterly flow, though many places stay largely dry with some sun.
- Clear nights continue to bring chilly starts and occasional ground frost, creating large swings from cold mornings to mild or warm afternoons, especially inland where the easterly wind favors higher readings than the coast.
- Public-health guidance highlights moderate UV levels of 3 to 4 that can cause quick sunburn, and the RIVM expects little overall nuisance from Easter fires but advises smoke‑sensitive people to stay indoors and avoid heavy exertion if smoke is present.
