Anyone else have a problem with weather widget? Mine won't load the data. Just got the Forerunner 45 today. Seems peculiar.
Make sure you have location services enabled on your phone, and maybe do something on the watch with GPS, just to make sure both know your location. Then give it maybe 15 minutes. I think it uses your phone for the location, but may use the location from your watch as a backup or something.
The watch also needs to be connected to your phone.
