Foliage progress in Hokkaido Oct 2023

Hi All,

I have this silly question 😅 Do you have any idea how long does it take from 30% colouring to best time to see?

I'm checking weathernews everyday but there's not much progress (30% for almost 10 days in Jozankei area). Autumn seems to come so late this year.

If you are an autumn expert, help me please.

There are days when the minimum temperature in the morning drops below around 8 degrees, and the leaves will start to change color after a while, so if the temperature reaches that temperature, the leaves will turn red.
