Official National Weather Service forecast for the nearest NWS forecast point.
Your search goes to the weather services only to look up the forecast point — no location is stored. Data: National Weather Service (NOAA).
Calculation details
Forecast data comes from weather.gov for supported US locations and can change without notice. Coordinates and normal web-request metadata are sent to weather.gov only after you request a forecast. Verify safety-critical conditions through official alerts.

What does this calculator estimate?
A US weather forecast shows official National Weather Service conditions. Enter a ZIP code or city to see the current weather and forecast.
- Official NWS data
- Current conditions + multi-day forecast
- Free, no signup
Where the forecast comes from
The tool uses the National Weather Service API — the same official data behind most US weather apps. It geocodes the location and returns the NWS forecast for that area, including current conditions, highs/lows, and precipitation.
Limitations to watch for
Forecasts are model-based and update frequently — treat day 3+ as trends. The NWS service covers the US (and territories); international locations need a different service. For severe weather, the NWS issues official warnings — check them directly.
How to use it in practice
Enter a ZIP code or city to get the official forecast. Use it for planning trips, work, and events. Cross-check alerts on weather.gov during severe weather.
['Enter a ZIP code or city.', 'Read the current conditions.', 'Scroll the multi-day forecast.']
