Other than that, every season seems to be basically the same. Corthas is always cold, Thanalan is always hot, the Shroud is always temperate, and these don't really vary with the seasons. You can assume, then, that Hydaelyn's axial tilt is basically straight up and down, making the angle of Hydaelyn's sun's rays the same for any given spot on the surface all throughout the year.
Actually, the reason why we don't see any distinctions in several of the places that you mentioned is literally due to magic.
Coerthas was actually an unchanging set of grassy highlands. Then Dalamud fell, which reportedly released enough aether to permanently mess with the climes themselves, resulting in an endless and unrelenting winter.
As for Thanalan, I can't remember where I heard this, but it's possible that Thanalan isn't actually a desert because it doesn't rain, but because Thaumaturges screwed with the aether at one point and ruined the place.
Again, I can't remember where I heard the second one, so take it with a grain of salt. The first bit on Coerthas, however, is accessible information within the game itself.
However, based on the Coerthas example, I think we might be able to propose the idea that the reason why we don't see any climate changes is because the world's aether keeps everything locked into certain specific climates, either naturally or due to other reasons. If that's the case, then we wouldn't see climate changes regardless of the tilt of Hydaelyn's axis.
