You can add weather forecasts directly into your Google calendar so that you easily know if weather is expected to impact your upcoming plans.

Then for the Show weather based on my location entry select a unit for the temperature, either F or C.

Then click the Save button. Google will then put the weather forecast at the top of every day in your calendar.
