How this service works
Weather forecast for coordinates: 7 day forecast periods, temperature, wind, precipitation, conditions text. JSON. Pass ?lat=<latitude>&lon=<longitude>. US National Weather Service.
Output
A JSON object containing the input lat/lon, a generated_at Unix timestamp, and an array of up to 14 NWS forecast periods — each with a period name (e.g. 'Tonight', 'Monday'), temperature value and unit, wind description, and a human-readable forecast text string.
Example use cases
Weekend rain check for campsite
“I'm planning a camping trip this weekend near Asheville, NC — the campsite is around 35.5951° N, 82.5515° W. Can you pull up the NWS forecast and tell me if it's going to rain Saturday or Sunday, and what the temperatures and wind will be like?”
Week-ahead forecast for outdoor event
“We have an outdoor concert at Millennium Park in Chicago on Friday evening. The coordinates are roughly 41.8827° N, 87.6233° W. Can you grab the 7-day NWS forecast and walk me through the conditions for Friday and the days leading up to it, including wind and any chance of precipitation?”
Wind conditions for drone flight planning
“I need to fly a drone at a job site in Austin, Texas — coordinates are 30.2672° N, 97.7431° W. Can you check the National Weather Service forecast for the next several days and highlight any periods with high winds or bad conditions that I should avoid?”
Technical details
Endpoint
GEThttps://cycle-angela-lamp-hamburg.trycloudflare.com/api/weather/forecast?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, multi-day weather forecast data for a specific US geographic coordinate — especially when you need the official NWS forecast periods with temperature, wind, and narrative text. Prefer this over generic weather APIs when you specifically need NWS-sourced data or need the named period format (e.g. 'Monday Night'). Not suitable for non-US locations.
Side effects
- Coordinates outside the US (NWS only covers US territories) — likely returns an error or empty periods array
- Invalid or missing lat/lon parameters — returns a 400-level error
- NWS upstream API outage or rate limiting — may return a 500-level error or stale data
- Coordinates in a valid US location but with no NWS grid coverage (e.g. remote ocean areas) — may return empty or partial periods
