BusyCal can display a 7-day weather forecast and moon phases in your calendar.
Important Notice: BusyCal 2, or older versions of BusyCal 3.5.x, will no longer connect to a weather service, as Weather Underground has shutdown their service. You need to ensure you're on v3.6 or above for weather updates to work. BusyCal now uses Dark Sky for weather updates. FAQ on this is available here.
BusyCal can display a 7-day weather forecast and moon phases times in your calendar.
To display the weather, choose BusyCal > Preferences > Weather, select the “Show weather” checkbox, and then select “At current location” or manually enter the ZIP code or city code for your area. You can also choose Fahrenheit or Celsius from the “Temperature scale” pop-up menu.
Note: To display weather at your current location, BusyCal requires access to Location Services. The first time you open BusyCal you should be presented with a dialog asking if you want to grant BusyCal permission to access Location Services. If you did not grant BusyCal access to Location Services at that time, you must do so manually, by going to System Preferences > Security & Privacy > Privacy > Location Services and then selecting the checkbox next to BusyCal.
You can display the weather graphics in three different formats: Small, Large, or Background; choose your desired size from the “Weather graphics” pop-up menu. When the size is set to Small or Large and you hover your pointer over the weather icon, an extended forecast is displayed. If you click the icon you’re redirected to DarkSky.net.
