残雪期雪渓滑落に厳重警戒。稜線は突風注意

Mt. Hakusan summit currently stands at -0.3°C, feeling like -5°C, with base temperatures around 10°C. While no significant snow depth is reported at the summit, early May on Hakusan is still a period of lingering snowfields. Expect hard-frozen snow patches in shaded areas and gullies along popular routes like the Sabo Shindo, and around points such as Midorigaike on the pond circuit.

These snowfields will soften as daytime temperatures rise to 5.7°C, but the risk of slipping remains high. Carrying microspikes or light crampons is essential for safe passage. Gusts up to 13.9 m/s are possible on exposed ridges, requiring a windproof outer shell and careful foot placement.

Recommended layering includes a wicking base, fleece mid-layer, and a waterproof/windproof shell, supplemented with an insulating jacket for breaks. The risk of hypothermia is present given the sub-zero wind chill in the morning and evening. Thunderstorm risk is low. Monitor conditions closely throughout your ascent, especially for ground stability. Overnight temperatures will drop back below freezing.
