How to complete Weather Week Collection Challenges in Pokemon GO
Pokemon GO's Weather Week is here, and if you're eager to find out what the Collection Challenges are and how to catch all of the featured creatures, I've got you covered.
Collection Challenges are a fun way to show off how many events you've completed in the game. However, the Weather Week challenges require a bit more effort from players this time, so find out more below!
How to complete Collection Challenges
The Weather Week Collection Changes involve catching certain Pokemon that will be more likely to appear during the event, but some of these Pokemon will only appear in certain weather conditions. This might make it a lot harder to complete the challenges this time.
Thankfully, you'll be able to find these weather-specific Pokemon by completing Field Research Tasks too, so if you want to complete the Collection Challenges you'll want to finish lots of them, as these don't require you to have any sort of specific weather conditions.
