Create the subscription
- In GCal, choose File → Add Weather Forecast Calendars….
- Search for a city and select the matching result. Check the country or region when several cities share a name.
- Use the copy control to copy the calendar URL. GCal opens Google Calendar’s add-from-URL view.
- Paste the link and choose Add calendar. Repeat for another city if needed.
Choose where it appears
Select the new subscription in the main Google Calendar sidebar. To include it in the native agenda, connect that Google account and select the weather calendar in Settings → Calendar once it is listed.
If the forecast is delayed
This is a subscribed calendar supplied by a weather service. It is not a live weather widget. Forecast changes depend on the feed and Google’s subscription refresh timing. Check the selected city and the subscription in Google Calendar before adding a duplicate.
To stop displaying it, deselect the calendar. You can remove the subscription through Google Calendar’s settings when you no longer want it.
