Weather forecast for Mt. Fuji
Weather characteristics
Mt. Fuji is an isolated peak with an elevation of over 3,000 meters.
The complex interplay of winds from Suruga Bay and Sagami Bay, along with winds from the north, creates unstable airflow at high altitudes, resulting in severe weather conditions that have historically caused aircraft crashes. Significant differences in weather and temperature occur between the foothills (such as the 5th station) and the summit, and these conditions can change rapidly. Prepare your equipment to cope with sudden weather changes, and always check weather information before starting your climb.
- Due to the significant elevation difference between the 5th station and the mountaintop, there is a large temperature difference (approximately -0.6°C for every 100m of elevation difference), meaning that even in summer, temperatures at the mountaintop are comparable to mid-winter. Furthermore, even at the same temperature, wind chill lowers the perceived temperature (approximately -1.0°C for every 1m of wind speed).
- Even in summer, temperatures can drop to near 0 degrees Celsius before sunrise, and if you spend a long time waiting for the sunrise, there is a risk of hypothermia.
- In summer, thunderstorms are common on Mt. Fuji, and it's not unusual to experience sudden weather changes and continuous thunderstorms.
- During the snowy season, Mt. Fuji is constantly subjected to strong winds from the northwest, posing a risk of falling.
