Windrose: Weather Radar & Rain

See where the rain is headed with animated radar, a 3-hour nowcast scrub and a live satellite layer. Pro adds pressure maps, isobars and typhoon tracks. Free to start.

Windrose is a beautiful live weather radar with a 3-hour rain forecast you can scrub right on the map - free for everyone. Whether you're deciding if the rain will hit the picnic, planning a day on the water, or flying a light aircraft without onboard weather radar, Windrose reshapes itself for what you're doing.

At its heart is a smooth animated precipitation radar, free for everyone, so you can see exactly where the rain is - and now scrub past the present into a 3-hour rain forecast to see where it's heading. A colour-coded safety summary tells you, in one line, whether conditions are good, need caution, or are dangerous. And three purpose-built modes reshape the app for what you're actually doing.

OFFICIAL WARNINGS

• Official government warnings for your region, shown prominently and with alerts
• Hong Kong: Observatory rainstorm (Amber/Red/Black) and typhoon signals, thunderstorm and more
• United States: National Weather Service watches & warnings
• Get notified when a severe warning is issued, even when the app is closed

GENERAL

• Animated live precipitation radar with a smooth, scrubbable loop - zoom right in on the rain
• 3-hour precipitation forecast right on the radar - play past "now" to see where the rain is heading
• Live satellite cloud layer - so the map never goes blank at night or when it's dry

• Sudden-change alerts: a heads-up when rain, thunderstorms or strong winds are about to arrive
• Home & Work at a glance, plus current conditions, hourly and multi-day forecasts
• UV index with its category and sun-protection advice
• Air quality and pollen, sunrise & sunset

PRESSURE MAP (PRO)

• A full interactive surface-pressure map: a colour-coded pressure field with crisp isobars
• Highs and lows, plus animated wind flow that streams along the isobars - brighter trails mean stronger wind
• Scrub the timeline to watch weather systems move in and out, hour by hour
• Tropical-storm tracks, forecast cones and development areas from JMA and JTWC (for awareness only)
• Tap anywhere to read the exact pressure at that spot

MARINE

• Wave height, swell and wind-wave breakdown with direction
• Sea state, sea-surface temperature and currents
• Wind, gusts and pressure for boating and sailing

AVIATION

• Decoded METARs & TAFs with colour-coded flight categories
• Search any airport worldwide, or pick from the nearest fields by distance
• Nearby airports at a glance (VFR / MVFR / IFR / LIFR)
• Winds and temperatures aloft by altitude
• SIGMET hazards near you, plotted and decoded
• Freezing level, CAPE and a density-altitude calculator Built for general-aviation pilots who don't have weather radar in the cockpit. For situational awareness only - always get an official briefing.
