The Google nowcast

You can find short-term precipitation forecasts for rain, hail, or snow up to 12 hours in advance with the Google nowcast. The weather information box shows the Google nowcast when you search for weather data on a mobile device.

Important:

The start and end times that show are in the local time zone of the location you search for.
This high accuracy short-term precipitation information is available in the US and certain locations in Europe.

Our nowcast uses radar and numerical weather prediction data published by various data sources.

Should I expect precipitation during the day?

You can check the next precipitation event with the Google nowcast. All precipitation will show in the hourly precipitation forecast.

Why can't I find the Google nowcast?

If there is no forecast for rain, hail or snow, or if the forecast is too uncertain, the Google nowcast data will not display.

In such cases, all weather information is shown in the hourly precipitation forecast. In addition, the Google nowcast may not be available on all weather surfaces.

Reports on current weather conditions

When you search for weather info on Google, you might be asked to provide feedback on the current weather in your area. Your feedback helps us monitor the quality of weather results and update the data.

You can find and delete your feedback in My Activity. When you delete your feedback from your Google Account, the feedback is no longer associated with your account, but it can still help improve weather results.
