Free Buienradar — Live Rain Radar & Precipitation Forecast_
This free buienradar-style tool combines two open data sources. The animated map shows a global radar composite of recent rainfall plus a short nowcast, looped frame by frame. The chart below shows the expected precipitation for your exact location, which you can filter to the next 1, 2, 4, 8 or 24 hours. Near-term views (1–2h) use a live radar nowcast from Buienradar in Belgium and the Netherlands — radar extrapolation is the most accurate way to tell whether rain is about to start — falling back to 15-minute model data elsewhere. Longer views (4–24h) use hourly model forecasts and show a rain-probability line. Nothing is stored — your coordinates are only used to fetch the weather data.
FAQ & about the rain radar
FAQ — Buienradar / Rain Radar
What is this buienradar tool?
It is a free, browser-based rain radar and precipitation forecast. It shows an animated weather radar map of recent and upcoming rainfall, plus a precipitation chart for your location that you can filter to the next 1, 2, 4, 8 or 24 hours.
How accurate is the forecast?
The animated radar uses RainViewer global radar composites (roughly the past two hours plus a short nowcast). The precipitation chart uses the Open-Meteo API, which aggregates national weather models including ECMWF and DWD. Near-term nowcasts are usually the most reliable; the 24-hour view is a model forecast that can change.
Do the 1/2/4/8/24h filters change the map or the chart?
They change the precipitation chart and summary — how far ahead you look. In Belgium and the Netherlands the 1h and 2h views use a live radar nowcast from Buienradar (5-minute steps, radar extrapolation — the most accurate way to tell if rain is about to start). Elsewhere, or if the radar feed is unavailable, they fall back to 15-minute model data. The 4h, 8h and 24h views use hourly model forecasts and add a rain-probability line. The animated radar map loops the last two hours of radar plus a short live forecast (nowcast) — drag the timeline into the blue section, or just let it play, to see the coming frames.
Does it use my location?
It asks your browser for your location to centre the radar and forecast where you are. If you decline, it falls back to Belgium (Brussels). You can also search for any city or place by name.
Is my location stored?
No. Everything runs in your browser. Your coordinates are sent only to the open weather APIs to fetch the radar and forecast, and are never stored, logged or shared by this tool.
Is it free?
Completely free, no account, no ads. It runs entirely in your browser. It's one of the free tools at jasperbernaers.com.
