What you see: the animated map is the RainViewer global radar composite (national weather radars merged, ~10-min updates, with a short nowcast ahead). Charts and the 7-day forecast come from Open-Meteo (15-minute rain nowcast + hourly/daily model forecast). It works worldwide — search a place, use your location, or click anywhere on the map. Radar shows where rain is; the charts show where it's heading. Not for safety-critical decisions.
Free buienradar-style rain radar & weather forecast
This free buienradar alternative combines three views of the weather in one dashboard: a live animated rain radar map you can scrub through time, a minute-by-minute precipitation chart for the next 1 to 24 hours, and a full 7-day weather forecast with hourly temperature, rain and wind detail for every day. It starts at your location (or Belgium as fallback) and works for any place on Earth.
How to use it
Press play on the radar timeline to watch showers move, or drag the slider — frames to the right of "now" are the nowcast, a short radar-based prediction. Use the window buttons (1h–24h) above the rain chart to answer "can I cycle home dry?". Click any day card in the 7-day strip to see that day hour by hour. Click anywhere on the map to get the forecast for that exact spot.
Frequently asked questions
Is this the official buienradar?
No — it's a free, independent buienradar-style dashboard. It combines the RainViewer global radar composite with the Open-Meteo forecast model. No ads, no signup, no cookies.
Where does the radar data come from?
RainViewer merges data from hundreds of national weather radars worldwide — including the KMI/KNMI radars that cover Belgium and the Netherlands — into one composite, updated roughly every 10 minutes. The frames after "now" are a radar-extrapolation nowcast.
How accurate is the minute-by-minute rain forecast?
The next-hours chart uses Open-Meteo's 15-minute precipitation product, which blends radar extrapolation with high-resolution weather models. For the first 1–2 hours it's typically right to within 10–20 minutes. Beyond ~2 hours, hourly model output takes over and uncertainty grows — treat the 8h/24h view as a trend, not a promise.
Can I see the weather for the coming days?
Yes. The 7-day strip shows daily min/max temperature, expected rain (mm and probability) and maximum wind. Click any day to open an hourly chart for that day — temperature curve, rain bars and wind — plus sunrise and sunset times.
Why does the radar show rain but it's dry outside (or vice versa)?
Radar measures reflections high in the atmosphere. Light drizzle can evaporate before reaching the ground (virga), and very local showers can slip between radar beams. The composite also lags reality by a few minutes. Combine the radar with the minute-by-minute chart for the best picture.
Does it work outside Belgium?
Yes, worldwide — radar coverage depends on national radar networks (excellent in Europe, North America, Japan, Australia). The forecast charts work for every location on Earth. Search any city, or click the map.
Is it free and private?
Completely. No account, no ads, no tracking cookies. Your location never leaves your browser except as coordinates in the public weather-API requests, and is never stored on any server of mine.
How often does it refresh?
Radar frames refresh every 5 minutes, the forecast every 15 minutes, automatically. The timestamp in the status box shows the last update.
