TLDR; what would weather be like with minimal axial tilt?
Included is a picture of my climate map and several perspectives of a paper model I made of the planet. The ocean covers over half the planet, which is rather small. It has nearly no tilt, and 2 moons; a bigger moon Aurie that is round but not perfectly circular which has some impact on tides but not too strong, and a smaller moon Chi which is too far and small to have a significant tidal impact. I’m thinking/hoping/praying that with a small tilt comes nearly no seasonal change, yes? Or... Is the tilt vital to life itself? And for that matter, can anybody help me figure out what the weather would be like on a planet with no axial seasons? I know I’m asking a lot, and I’m new to this site so I understand if this is removed. I’ll post an “answer” of my other terrestrial map so you can refer to the areas by name by they are in pretty obvious 4 quarters: NW, NE, SE, SW.
