What we ingest
High and low tide predictions, plus coastal wind, visibility, temperature, pressure and observed water level, for the same 5 featured CO-OPS stations — four on the Gulf Coast and one at San Francisco — chosen for the offshore helideck check. CO-OPS publishes 3,499 tide-prediction stations and 316 meteorological stations (both measured 2026-07-29); we ingest these five, and no station outside the continental coastline is in this feed.
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.
