Google Calendar’s Weather feature displays the weather forecast directly in your calendar to make it easier to see if upcoming events fit with the 4-day weather forecast.
To view weather forecasts in Google Calendar, follow these steps:
1. Go to Google Calendar.
2. Click Settings in the upper-right corner of the page.
3. Input your City and State or Zip Code in the Location textbox.
4. In the Show weather based on my location section, select either the °C or °F radio button.
5. Click “Save.”
You will now notice weather icons on your calendar that indicate the forecast for that day.
Mouseover the icon for a quick look at the high and low forecasted temperatures. For a more detailed look, click the icon and the 4-day forecast will be displayed, along with current weather conditions.
