US Current Weather Observations API - NWS Station Temperature

Current conditions from US National Weather Service stations, straight from api.weather.gov. No scraping, no HTML parsing, no browser.

Give it a station id, or a point on the map and it finds the nearest reporting station for you.

The thing this Actor does differently

Weather sensors go missing. A station reports temperature but not visibility. Another has no gust reading. This is normal and it happens constantly.

Most pipelines paper over it. Fill a missing wind gust with 0 and your dashboard now says "no gusts" when the truth is "nobody measured". Fill a missing temperature with 0 and you have just invented a freezing day.

This Actor leaves missing readings as null, and tells you how many of the nine core measurements were actually taken:

{ "stationId": "KJFK", "temperatureC": 20, "windGustKmh": null,
  "fieldsMeasured": 8, "fieldsMissing": 1 }

If a station returns an observation with no measured values at all, that is not reported as a success — you get a row explaining it instead.

What you get

Field
stationId / stationName / elevationM	which station reported
observedAt	when the observation was taken (ISO)
textDescription	Clear, Mostly Cloudy, … as NWS words it
temperatureC / temperatureF / dewpointC / dewpointF	both units, null if unmeasured
relativeHumidityPct
windSpeedKmh / windGustKmh / windDirectionDeg
barometricPressurePa / seaLevelPressurePa / visibilityM
windChillC / heatIndexC	only present when conditions call for them
precipitationLast3HoursMm / maxTemperatureLast24HoursC / minTemperatureLast24HoursC
rawMessage	the original METAR string, if the station sends one
fieldsMeasured / fieldsMissing	how much of this row is real
resolvedFromPoint	set when you gave coordinates instead of a station id
checkedAt	when this Actor asked

Input

{ "stations": ["KJFK", "KORD", "38.89,-77.03"], "maxRetries": 3 }

Input
stations	NWS station ids (KJFK) or points as "lat,lon". A point costs two extra requests while the nearest station is resolved, and the row records which point it came from.
maxRetries	Retries when NWS rate-limits or has an outage.

An input that cannot be read — "Tokyo", "K1" — produces a row saying exactly that, and no request is sent to NWS.

Measured on 2026-08-30: KJFK, KORD and KSEA all returned observations; a point in Washington DC resolved to KDCA out of 54 nearby stations.

Billing

Charged per observation delivered. Rows that explain a bad input, a missing station, or an NWS outage are free. If you set a maximum total charge on the run and it is reached, the run stops and says so in the log and the run status rather than handing you a partial result that looks complete.

Source and conduct

Data comes from the National Weather Service public API. NWS states the information is "open data, free to use for any purpose" and asks that clients identify themselves with a User-Agent; this Actor sends one that includes a contact URL, so NWS can reach us rather than block us if anything ever looks wrong.
