Live weather radar with rain alerts, local forecast, and hurricane tracker. The most accurate radar map for Android - made for people who need accurate weather, right now.

Going outside, planning a day out, flying a drone, or watching a storm approach? Rain Viewer shows the actual rain on the map - live radar plus rainfall totals showing how much has already fallen. Data goes from radar to your screen in seconds - direct from the source, not a third-party feed. Our radar pipeline runs in millions of installs and feeds several major weather brands.

The radar map you actually use:

Tap the map to see rain intensity at any point. Tap satellite for cloud top temperature. Tap an alert zone for the full advisory

Live indicator shows when you are seeing the most recent scan. New frames appear automatically

48-hour history. 2-hour rain forecast updated every 10 minutes. 60fps vector map with precipitation arrows

Coverage in 80+ countries across the Americas, Europe, Asia (Japan, India, Thailand, China, South Korea), and Oceania

Hourly and 14-day forecast: Temperature, weather conditions, and chance of precipitation hour by hour for 72 hours. Wind direction and speed too, with units you choose: km/h, mph, m/s, knots, or Beaufort. Tap any day to see UV index, humidity, wind, sunrise, and sunset (Android only). Models: ICON, GFS, HRRR, ECMWF, and WRF-ROMS Thailand.

Minute-by-minute precipitation: When rain is on the way, the forecast screen shows when it starts, peaks, and stops.

Rainfall Totals (QPE): See how much rain has actually fallen. Pick a window - 1, 3, 12, 24, or 48 hours - and tap any spot on the map for the exact amount in millimeters or inches, plus a Trace to Extreme rating. Built on QPE (quantitative precipitation estimates) from our radar pipeline. Included with any Rain Viewer subscription (Essential or Pro).

Radar scan age: Tap the map to see exactly when each area was last scanned. Parts of a radar frame can be minutes apart, so the timing tells you whether to leave now or wait out the rain. Saved locations show freshness at a glance.

Rain alerts you can rely on: Set custom alerts for your locations. Get national severe weather alerts from the US, most of Europe, Thailand, Saudi Arabia, and more. Set thresholds so you only get notified for what you care about.

Hurricane and storm tracker: Get timed alerts that show exactly when a storm reaches you. Choose hurricane wind speed units: mph, km/h, m/s, or knots.
