About Rev Weather Watch

Rev Weather Watch, by His Super Affiliates, is a free real-time world weather app. Search any place on Earth — or tap the map — for current conditions, a rain nowcast for the hours ahead, a 48-hour hourly forecast with interactive charts, a 14-day outlook, live radar and satellite, air quality, UV, pollen, marine conditions, sun and moon times, and active severe weather alerts in the United States.

How accurate is it?

No one can promise the weather. What this app does is show you the evidence: each day's forecast is compared across up to seven independent global models — ECMWF, NOAA GFS, DWD ICON, Canada's GEM, Météo-France, the UK Met Office and Japan's JMA. When they agree the dot is green and you can plan on it. When they disagree the dot turns red and you should check back. Forecast skill is strongest for the next three days and falls with each day after.

Is the data real-time?

Yes. Conditions refresh every 5 minutes and a live indicator shows exactly how old the data on screen is. In the United States the app also shows the latest measured reading from the nearest official weather station. Radar and satellite images are the newest each provider has published, typically 10 to 30 minutes old.
