How this service works
Global weather forecast by latitude/longitude: up to 48 hours of temperature, humidity, wind, cloud cover and next-hour precipitation in UTC with explicit units and model update time. Forecasts, not live observations; missing fields are null and sparse periods are not interpolated. Based on MET Norway data (CC BY 4.0); outage cache is flagged stale.
Output
An array of hourly forecast periods in UTC covering up to 48 hours, each containing available fields from: temperature (with units), humidity, wind speed and direction, cloud cover percentage, and next-hour precipitation probability. Missing data fields are null rather than interpolated. The response also includes the model's last update timestamp and a staleness flag if the data is from an outage cache.
Example use cases
Outdoor event planning check
“Can you pull the 48-hour weather forecast for latitude 51.5074, longitude -0.1278? I need to know temperature, wind speed, and any rain expected hour by hour.”
Drone flight condition check
“Check weather conditions for the next 6 hours at latitude 37.7749, longitude -122.4194 — specifically wind speed and cloud cover, so I can decide if it's safe to fly.”
Smart irrigation scheduling
“Get me the precipitation and humidity forecast for the next 24 hours at latitude 34.0522, longitude -118.2437 so I can decide whether to run the sprinklers tonight.”

Endpoint
POSThttps://weather.openverbs.com/v1/forecast?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured hourly weather forecasts keyed by precise latitude/longitude coordinates anywhere in the world, especially when MET Norway's high-resolution model coverage is sufficient. It is well-suited for automated agents that need machine-readable, unit-explicit forecast data with explicit null handling rather than interpolated estimates. Prefer this over general weather APIs when you need transparent data provenance (CC BY 4.0 MET Norway) and explicit staleness signaling during outages.
Side effects
- Coordinates out of valid range (-90 to 90 lat, -180 to 180 lon) return a validation error
- Hours parameter exceeding 48 or below 1 returns a validation error
- Stale cache served during MET Norway outage, flagged with a staleness indicator in the response
- Sparse forecast periods returned if native model periods are limited — no interpolation is performed
- Missing fields returned as null when the weather model does not provide that variable for the period
