日中霧雨に注意。気温低下と足元泥濘化進む

Daytime conditions will be characterized by light drizzle. While the morning is cloudy, light mist and rain are expected from noon through the evening. The current summit temperature is 12.6 degrees Celsius, while the base is 15.6 degrees, indicating a 3-degree temperature difference between the summit and base. At the 1086m summit area, the combination of drizzle and wind will further lower the perceived temperature, increasing the risk of hypothermia if clothing gets wet. Waterproof and breathable rain gear is an essential piece of equipment.

Although Sapporo Kokusai Ski Resort features many gentle slopes, the drizzle will make trails wet and muddy. Especially on unpaved paths and forest courses, surfaces will become slippery. Waterproof trekking shoes are highly recommended to ensure stable footing. A significant temperature drop of 7 degrees Celsius is anticipated during the forecast period at the summit area. Therefore, carry an extra insulating layer from the start of your trip to prepare for sudden changes in conditions.

Gusts up to 10m/s are expected around midday. While this wind speed generally does not impede movement, combining it with reduced visibility from the drizzle could lead to disorientation in exposed areas near the summit. The risk of lightning is low. The drizzle is forecast to subside by evening, clearing to fair skies overnight, but temperatures will drop to around 8 degrees Celsius. Nighttime activities are not recommended, and making early decisions to turn back is crucial.
