霧雨と低い視界。足元滑りやすく注意

Niseko Annupuri summit currently reports cloudy conditions with visibility under 1km. The temperature is 8.1℃, with a light wind of 0.76m/s. There is a 6℃ temperature difference from the base. Light drizzle is expected to continue throughout the day, with an 80% chance of precipitation by 12:00 and a 100% chance of heavier drizzle by 15:00. Temperatures will peak around 12.9℃ at midday before gradually declining.

Trail conditions will be wet to muddy due to the persistent drizzle. Poor visibility poses a significant risk of disorientation, especially on the exposed ridge access routes of Niseko Annupuri. Caution is advised to prevent slips and falls on the slick surfaces. There is no snow cover, so no concerns about lingering snow or ice.

Despite weak winds, the combination of drizzle and moisture can drastically lower the perceived temperature. Daytime real-feel temperatures will range from approximately 8℃ to 11℃, but the risk of hypothermia due to wet clothing is present. A fast-drying synthetic or merino wool base layer, a thin fleece mid-layer, and a waterproof-breathable rain jacket and pants are essential. Trekking poles will also be beneficial. While the risk of lightning and strong winds is low, be vigilant about poor visibility and potential body temperature drops.

Heavy drizzle will persist into the evening after 18:00, with temperatures dropping to 8.2℃. By 21:00, conditions will clear, but temperatures will fall further to 4.6℃. Nighttime activity should be avoided.
