NWS Official Weather: Climate Reports and Observations

Live high/low so far, METAR observations and official NWS daily climate reports for US weather stations. Enter a station or a Kalshi temperature series (KXHIGHNY) and get the referenced station's data. Public government data, no API keys.

Official NWS daily climate settlement values, hourly observations and 6-model forecasts with the spread between models, for the stations Kalshi and Polymarket temperature markets settle on.

Hourly METAR/ASOS observations for any ICAO station (temp, dewpoint, wind, visibility, ceiling, raw METAR) with per-day high/low summaries — the temperatures Kalshi weather markets settle on. Official sources with automatic fallback. No login.
