How this service works
Get a global weather forecast for a city/locality name or exact coordinates. Returns normalized day/night or hourly periods worldwide: NOAA/NWS is preferred within supported U.S. coverage for optional station conditions and active alerts, while MET Norway provides an attributed open-data fallback globally.
Output
A JSON object containing an array of forecast periods (day and night), each with name, start/end times, temperature (°F), wind speed and direction, short and detailed forecast text, precipitation probability percent, relative humidity percent, dewpoint, and isDaytime flag. Also includes location metadata (city, state, lat/lon, timezone, NWS grid office), source provenance (dataset, provider, attribution, upstream URLs), and explicit coverage limitations noting NWS-supported U.S. locations only.
Example use cases
Outdoor event weather planning
“I'm organizing an outdoor event in Denver, Colorado this weekend — can you pull the NOAA forecast for coordinates 39.7392, -104.9903 and tell me the temperature, rain probability, and wind for Friday evening and Saturday daytime?”
Travel packing weather check
“I'm flying to Miami next week — can you get me the NWS day and night forecast for coordinates 25.7617, -80.1918 so I know what temperatures and precipitation to expect?”
Smart home weather-triggered automation
“Check the current NOAA weather forecast for my home in Chicago at coordinates 41.8781, -87.6298 — I need precipitation probability and wind speed for tonight and tomorrow so I can decide whether to run the sprinkler system.”
Technical details
Endpoint
POSThttps://apiacre.com/v1/data/us-weather-forecast?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need normalized, structured NOAA/NWS forecast data for U.S. locations via a paid, reliable API wrapper that handles NWS quirks and normalizes fields. Prefer it over raw NWS API calls when you need consistent JSON output with provenance, humidity, and precipitation probability already extracted. Ideal for agent workflows that need weather data without managing NWS grid lookups or raw API parsing.
Side effects
- Coordinates outside NWS coverage (e.g. non-US territories or unsupported offshore areas) — returns error or coverage limitation notice
- Invalid or malformed latitude/longitude input — returns validation error
- NWS upstream API unavailable or rate-limited — may return 502/503 or upstream error
- Coordinates in US waters or territories not covered by NWS point grid — returns coverage limitation
