Since July 12 the weather on Mt. Fuji has been extremely placid with light winds, minimal cloud cover and frequent blue skies.
Looking towards the next week however, the weather is forecasted to start getting more turbulent with moderate winds and light precipitation expected. While the weather on lower elevations isn't expected to exceed 30kph, the weather on the summit is expected to be around 45kph starting tomorrow, with winds coming out of the North.
Climbers on the Yoshida/Subashiri routes can expect moderate gusts and patches of rain throughout today and tomorrow.
While it may be hard to believe if you're starting from Tokyo, temperatures on the summit are forecasted to be between 5-7 degrees C, with winds increasing the chill factor to be about 0-4 degrees C before wind chill.
Current conditions on Fuji continue to be moderate with mild winds and patches of passing rain clouds. Party cloudy/rainy conditions persist although the rain is likely to be relatively light. In the last few days, the chances of thunder and lightning have been higher than usual with observed storms yesterday and conditions favoring the development of thunderheads.
A beautiful day on the mountain, but a major thunderstorm hit in the middle of the day causing a bit of chaos.
While winds are expected to stay calm in the coming days, it is expected that it will be raining off and on throughout the day tomorrow. Later in the week winds will be picking up as the precipitation is expected to subsite on Friday.
Further lightning storms are forecasted in the general area so climbers should be very careful as they climb and seek shelter immediately in the event of lightning.
Fair weather persists on Fuji with calm winds and hot temperatures all the way to the summit. Patches of clouds will block out the sun from time to time. Risk of sunburn above 3000 meters is especially high. As the day cools off, temperatures will drop near freezing.
Conditions are expected to stay mild but rain is expected to pick up in the next few days. Proper rain gear is always required when climbing Fuji.
A fair how do you do from Fuji! Fuji has been beautiful recently as the weather has been fair and clear with a high pressure system lingering in the area, bringing blue skies and light winds all the way to the summit.
Temperatures on the summit are still quite cold overnight at about 3 degrees C even though Tokyo is experiencing an unusually hot early summer. Climbers should always carry proper warm gear and remember that weather on Fuji suddenly changes without any warning.
Current conditions on the mountain on clear with very little wind and moderate temperatures. While clear conditions are likely to persist, clouds and weather can suddenly appear so climbers should always be careful and bring the correct gear when attempting a climb.
High winds continue on Mt. Fuji, especially at elevations above 3,000m. Current conditions are patchy with bands of rain clouds passing along Mt. Fuji, causing intermittent strong rains or hail at higher elevations. Temperatures are still quite cold with a range of 5-9c between 2,000m-3770m, but with strong winds and rain, the "feels like" temperature will be significantly colder, most likely around zero and minus temperatures.
The transition to fairer weather will begin tomorrow with the storm systems lighting up. Sunday is currently predicted to be the day when this long-lasting storm finally completely passes.
Current rainy conditions persist on Fuji but the more severe rains are predicted to stay on the Sea of Japan side and not cross the landmass.
The low pressure system of Typhoon #7 continues to rage in the Sea of Japan sucking in air from the Pacific ocean across the mainland and into its vortex. This results in extremely high winds on Mt. Fuji.
As the typhoon moves northward, calmer conditions should take hold in the Fuji area in the next few days. At this time, climbing Fuji is NOT recommended at any elevation.
