Re: Can you check weather in other worlds?
I don't think there is a way to do that but I agree, it's not fun when you go somewhere like a festival or vacation and it is raining or snowing. So to deal with that, you could do what I did.
Most of the places I go like that, land on a community type lot when you travel. So I placed a Doctor June's weather machine on at least one community lot in the zones that I go to a lot so I can change the weather to clear when I get there. Then when I do arrive and it's raining or snowing, the first thing I do is change the weather.
For vacations in Granite Falls and Selvadorada, I have one on the rental lot that I use the most in each place. I also placed one on the market lot in Salvadorada and the Ranger Station in Granite Falls state park. In Selvadorada, you can also place one on the Trailhead lot. You have to place them before you go since you can't edit those lots once your sims are there.
The weather machine weather change will sort of wear off over time so if you stay long enough at any one place, you might have to change the weather again later but for the most part, I usually only have to do it once for most places.
So that's a way to control the weather so you can avoid having your sims wet and miserable when you want to attend the CL festivals and enjoy their vacations.
Hope this helps.
