What we ingest
Raw METAR text + parsed fields for reporting stations across the covered regions listed below — roughly 5,000 stations in the continental US, plus Hawaii, Puerto Rico, the US Virgin Islands, Guam, the Northern Mariana Islands and American Samoa. Station density in the island territories is a fraction of the continental figure, so an airport there may have no nearby reporting station at all. Alaska is not in this feed: Alaskan observations reach us through the Nav Canada METAR/TAF relay listed separately below, because two jobs writing the same station and observation time would collide.
Where this feed reaches
A region on this list means we fetch it. It is not a promise of station density: a listed region can still have sparse or no reporting sites near a given airport. Where a feed does not reach a region at all, this page says so instead of showing an empty panel.
- Continental United States
- Hawaii
- Puerto Rico and the US Virgin Islands
- Guam and the Northern Mariana Islands
- American Samoa
