Forecasts from a public weather source
Enter a five-digit US ZIP code. Zippopotam.us resolves the approximate location; the National Weather Service returns forecast periods for its coordinates. The result includes the location, forecast update time, temperatures, wind and the source's own description.
A ZIP code covers an area, so the forecast point may not match your exact street. Open the source link for details and current watches or warnings.
Coverage and safety limits
This tool covers US ZIP codes only. The underlying NWS API is public and can be temporarily unavailable. An unknown ZIP or location outside forecast coverage receives a clear error.
Forecasts are informational, not an emergency alert system. For urgent weather decisions, follow official local guidance.
