NWS Weather Station Observations — Resolution-Grade Daily Highs

Official NWS/NOAA station observations — the exact same station data Weather Underground displays — with daily highs/lows computed on local calendar dates, not UTC. If you settle anything against "the high temperature in NYC today" (prediction markets, weather derivatives, parametric triggers), UTC-bucketed daily data is wrong twice a day. This actor does the timezone math correctly.

Why this one

Same source as Weather Underground — WU displays NWS METAR station data; this fetches it from the authoritative api.weather.gov feed directly
Local-date daily highs — observations are bucketed midnight-to-midnight in the station's own timezone (DST-aware)
City aliases — nyc → KLGA, los angeles → KLAX, seattle → KSEA... the exact stations weather markets typically specify
Raw observations available — full temperature/wind/pressure/humidity series when you need more than highs

Output example

{
  "type": "daily_summary",
  "station": "KLAX",
  "date": "2026-06-11",
  "maxTempF": 78.8,
  "minTempF": 62.1,
  "maxTempC": 26.0,
  "minTempC": 16.7,
  "observations": 28,
  "timezoneOffsetHours": -7
}

Use cases

Prediction market resolution — settle weather markets against the same station WU shows
Energy & demand modeling — accurate daily extremes for load forecasting
Parametric insurance / weather derivatives — settlement-grade station data
Climate datasets — clean daily series for any US station

Input

  "stations": ["KLAX", "nyc", "KORD"],
  "startDate": "2026-06-01",
  "endDate": "2026-06-11",

  "rawObservations": false

FAQ

International stations? This actor covers US NWS stations. International METAR support is on the roadmap.

How fresh is today's high? Observations update roughly hourly; today's max is a running max until the local day ends.
