午後霧雨と山頂気温低下。防水対策と防寒着は携行せよ

Current conditions at Sapporo Kokusai Ski Resort summit are mostly clear with a temperature of 12.1 degrees Celsius, a perceived 10 degrees Celsius, a noticeable 3-degree difference from the base. The morning will start with clear skies, offering pleasant conditions and excellent visibility of over 20 kilometers, allowing for enjoyment of the surrounding scenery.

However, a light drizzle is expected to begin around noon, with a 100% chance of precipitation by 3 PM. Although the rainfall is minimal, prolonged exposure could lead to chilling, especially during the latter half of the long 3,600m runs, potentially slowing down movement. The summit's perceived temperature will drop to around 12 degrees Celsius, feeling even colder when wet. It is crucial to carry waterproof outerwear and a mid-layer such as a light fleece or long-sleeved shirt, adjusting layers frequently to regulate body temperature.

The ground will become wet to muddy in places due to the drizzle. With no snowpack, crampons or microspikes are unnecessary, but sturdy trekking shoes are essential. Gusts could reach up to 12.6 m/s, but this should not significantly impede movement.

Temperatures will fall to around 9 degrees Celsius at night, with a perceived temperature in the 5-degree range. The risk of hypothermia increases after sunset. Therefore, always carry a headlamp and extra warm clothing, and it is recommended to conclude activities before dark.
