Spring or fall semester as an exchange student?

I genuinly dont know where to post this. If this is the wrong sup please tell me where to go.

I might have an oppurtunity to spend a bit less than half a year in Japan as an exchange student. This isnt quite MovingToJapan as its not permanent, JapanLife or JapanTravel also dont quite fit so im lost.

TLDR: Should I apply for spring semester and live through the summer heat or fall semester and likely get sick multiple times?

The spring semester – from April to July (+ 1 month of travel in August). It is beautifuly green and warm, but im very bad with high temperature and humidity. I want to explore the neighbourhoods as much as i can and i know the weather will heavily limit me.

Edit: also typhoon season

On the other hand the fall semester – October to February (+ 1 month travel in March) is cooler. I think i prefer that as i can travel much better and not have issues with the temperature. However, im afraid ill get sick too often which sucks.

My questions are:

Do you think getting sick in Japan is somehow worse or more common than back home? And how is the experience of being sick there (i know thats silly but why not)

If you had to choose in which season you can live in Japan, when would it be?

Any general thoughts on my situation?

I dont know where i would stay as i dont know where i might get accepted but either Tokyo, Chiba or Kyoto. And of course i dont know if i will get accepted but i need to decide for which semester i want to apply.
