About this dataset
Terminal forecasts covering 24–30 hours of expected conditions at major airports. Raw TAF text + parsed fields including FM/BECMG/TEMPO change groups for ~700 TAF sites across the covered regions listed below — the continental US plus Hawaii, Puerto Rico, the US Virgin Islands, Guam, the Northern Mariana Islands and American Samoa. Alaskan TAFs reach us through the Nav Canada METAR/TAF relay listed separately below, not through this feed. Drives the AI departure/arrival window analysis and is central to the briefing tool.
Where this feed reaches
- Continental United States
- Hawaii
- Puerto Rico and the US Virgin Islands
- Guam and the Northern Mariana Islands
- American Samoa
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.
