Weather
Mount Fuji weather.
Fuji creates its own weather. Cloud caps, lenticular UFOs, summit windstorms, all from the same isolated cone. Here is what to expect through the year.

FAQ
Common questions
What is the best month for clear views?
December and January. Cold dry air gives the highest clear-day rate. November is a close third.
Why is Fuji so often cloudy?
It stands alone on the plain, so moist air rises against its slopes and condenses. Even on otherwise clear days, clouds can form by mid-morning.
Is it safe to climb in bad weather?
No. Sudden thunderstorms above 3,000 m are dangerous. Cancel or wait if a typhoon is within 500 km.
