There's a ton of apps and watchfaces on the existing Pebble appstore that showed the weather back when the earlier Pebbles were new. I don't think any of them still work, because they depend on being able to access services that were around back then. These new Pebbles conspicuously don't list the ability to show the weather.

There are current and recently updated apps for pebbles that show the weather. I practically see an update to one a few times a week when I skim the releases channel in the rebble discord.

I'm currently wearing a 2 Duo that shows the weather and outside temperature on the watch face.
