How this service works
7-day forecast for any US coordinate: periods with temperature, wind, precipitation chance, narrative. Source: National Weather Service. JSON.
Output
A JSON array of forecast periods covering 7 days, each with a period name (e.g. 'Tonight', 'Monday'), temperature and unit, wind speed and direction, precipitation probability, short and detailed narrative descriptions, and daytime/nighttime flag — sourced from the National Weather Service.
Example use cases
Pre-trip outdoor activity planning
“I'm planning a hike near Denver, Colorado this weekend — can you pull the 7-day forecast for coordinates 39.7392° N, 104.9903° W and tell me which days look best in terms of temperature, wind, and rain chance?”
Construction site weather monitoring
“We have a job site in Austin, Texas at roughly 30.2672° N, 97.7431° W — can you get the full weekly weather forecast so we can plan which days are safe to pour concrete?”
Agriculture irrigation scheduling
“Can you get the 7-day NWS forecast for our farm at 36.7783° N, 119.4179° W so I can see the precipitation chances and decide which days we need to run irrigation this week?”
Technical details
Endpoint
GEThttps://polyform.polyform-org.workers.dev/v1/weather/forecastWhen to prefer
Choose this endpoint when you need structured, multi-day weather forecast data for any US geographic coordinate, especially when you want NWS-authoritative data with period-by-period narratives, wind, temperature, and precipitation chance. Prefer this over generic weather APIs when you need official US government weather data tied to a precise lat/lon and want a ready-to-use JSON response without managing NWS API complexity directly.
Side effects
- Coordinates outside the US result in no forecast data (NWS only covers US territory)
- Invalid or malformed latitude/longitude values cause a parsing or bad-request error
- NWS upstream API unavailability may result in service errors or timeouts
- Ocean coordinates or remote US territories may not have coverage
- Rate limiting or payment failure returns a 402 error
