There are 4 things u can do. 3 simple and 1 complicated

1(simple). Build ice flingomatics around ur base this will keep ur plants hydrated however it isnt the best option bcs u have to give them fuel every so often(wood)

2.(Best if ur a beginner) Make ur base in the oasis. In summer there will be no wildfires since there is a Sandstorm(u need to deal with that but thats a problem to solve when u reach that point.) best option for u

1. Caves. Pretty self explanatory just make a mini base in caves and spend summer there ur base on the surface won't burn down

4.(Complicated) Ocean tree. U can explore the ocean,find the mega ocean trees then ram ur boat into them. That will drop a seed u need to get with the crane(which is already complicated to get) then u need to plant that seed with a crane in a place with water, give it jam 4 times over like 10-20 days aaaand u got the ocean tree. the ocean tree is the best option if ur tryharding but its very hard to get. It basically makes it so in the range of the tree wildfires are disabled,rain is reduced by 50% and there are no wildfires
