森林限界上は冬の体感。独立峰の強風に注意。

Yotei summit is currently cloudy with a temperature of 1.4℃, feeling like -2℃. The temperature difference from the base is over 10℃, indicating the unique cooling effect and wind exposure of this isolated peak. Cloudy conditions are expected to persist throughout the day. The temperature will rise to a maximum of 4.8℃ around noon, but gusts are predicted to reach 10.6m/s. Under these conditions, the apparent temperature will be around 0℃. Above the tree line at 1400m, the wind's impact will be significant, further lowering the perceived temperature.

Ground conditions are generally wet to muddy below the tree line, with no precipitation or snow accumulation. Above the tree line, rocky terrain is exposed and may be slippery due to low temperatures and moisture. While crampons or microspikes are not necessary, sturdy hiking boots and careful footing are advised.

Essential layering includes a moisture-wicking base layer, a fleece or light down mid-layer, and a windproof and waterproof outer shell. When traversing the rim of the summit crater, caution is advised against losing balance due to sudden gusts. Temperatures will drop to near 0℃ overnight with a possibility of light drizzle, so ensure to descend before sunset.
