トマム山 霧雨で足元注意

At 7:45 AM, Hoshino Resorts Tomamu summit is cloudy with a temperature of 15.4 degrees Celsius, feeling approximately 15 degrees Celsius. The base is 19.2 degrees Celsius, 3.8 degrees warmer than the summit. Cloudy conditions are expected to persist throughout the morning, with light drizzle starting around noon. Afternoon temperatures will hover around 18 degrees Celsius, but a rapid drop is anticipated in the evening. Winds are generally light, though gusts of up to 6.1 m/s are possible around noon.

Ground conditions will be wet to muddy due to the intermittent drizzle. Trails will be slippery, requiring careful footing. Under these conditions, clear views from the Unkai Terrace (Cloud Terrace) are unlikely. Even when using gondola access, waterproof rain gear is essential at the summit.

The automated risk assessment indicates a sharp temperature drop of over 7 degrees Celsius during the forecast period. From the daytime high of 18 degrees Celsius, temperatures will fall to around 10 degrees Celsius by early morning. To prepare for sudden changes during your activity, carry an extra insulating layer, such as a light fleece, in addition to waterproof and breathable rain gear. Perceived temperatures will range from 15 to 18 degrees Celsius during the day, dropping to 12 to 14 degrees Celsius in the evening. A wicking base layer, a light fleece mid-layer, and a waterproof shell are appropriate. While lightning risk is low, the combination of drizzle and falling temperatures overnight increases the risk of hypothermia. Early turnaround decisions are advisable. Crampons or microspikes are not necessary, but non-slip hiking boots are essential.
