富士山頂付近は真冬の様相。防寒対策を怠るな

Currently, the summit of Mt. Fuji is experiencing severe cold under cloudy skies, with an air temperature of -4.6 degrees Celsius and a wind chill of -8.3 degrees Celsius. Throughout the day, temperatures are expected to remain between -4.7 and -5.9 degrees Celsius, with gusts potentially reaching 9.9 m/s. The temperature difference from the base is significant at 12.6 degrees Celsius, meaning the perceived temperature will drop rapidly as you ascend the steep volcanic scree slopes starting from the 5th station.

While there is no snow accumulation, the combination of sub-zero temperatures and 99% humidity strongly suggests the presence of icy patches and thin black ice on the ground. Slippery conditions are highly probable, especially in shaded areas and on exposed rocky ridges. Above the tree line, where there is no shelter, strong gusts will quickly deplete energy, significantly increasing the risk of hypothermia.

Proper cold weather gear is essential for climbing in these conditions. Wear a quick-drying base layer, a warm fleece or down jacket as a mid-layer, and a windproof and waterproof hard shell jacket and pants as your outer layer. Gloves, a knit hat, and a balaclava are also mandatory. For your feet, always carry light crampons or chain spikes to prevent slips and falls on icy sections. Visibility is currently 4.7 km, but it may worsen if the clouds thicken. Continuously monitor weather and your physical condition during your climb, and avoid any reckless actions. Temperatures will drop further from evening into night, and icing will become more widespread.
