GET Interpolated Point Forecast

Retrieve interpolated forecasts for arbitrary geographic coordinates. This endpoint provides estimated weather forecasts at individual locations by interpolating values from the underlying gridded model output.

Unlike the point forecasting endpoint, which uses WindBorne’s custom modeling for higher accuracy, this endpoint generates values through spatial interpolation of the grid.

A model parameter must be provided to specify which weather model’s forecast to retrieve. You can find a list of available models here.

WM‑5c valid time

For WM‑5c, the valid time of a forecast is forecast_zero + forecast_hour , NOT initialization_time + forecast_hour .

WM‑5c runs every 20 minutes (initialization_time), but valid times stay on a fixed 3‑hourly cycle (forecast_zero). Multiple runs can share the same forecast_zero as later runs assimilate newer observations while keeping valid times stable.

Alternatively, you can use the time or valid_at (NetCDF/ZARR) parameter to request or use forecast data by valid time directly.

See Time in Forecasts for full details.
