穏やかな曇り空。高山植物群落を巡る好機

Mount Asahidake summit experiences calm cloudy conditions. The perceived temperature at 8 AM is 9.7 degrees Celsius. Daytime temperatures will hover around 12 degrees Celsius, but light winds will maintain a relatively stable perceived temperature. A base layer, a thin fleece mid-layer, and a windproof shell are sufficient for protection. Frequent adjustments to clothing are necessary during activity.

The ground primarily consists of dry summer trails. However, in wetlands where high mountain flora thrives and near water sources, muddy sections may be present. Crampons or microspikes are not required, but waterproof hiking boots are essential. Rain gear should be carried as a precaution. Visibility is excellent, exceeding 20 kilometers, offering extensive views of the Daisetsuzan mountain range.

Near the fumarole groups (Jigokudani) of active volcano Asahidake, there is a slight possibility of perceived temperature drops due to gas or inhalation of toxic gases. Even in summer, temperatures can be low, so careful health management is crucial. Around 3 PM, gusts may reach up to 8.7 m/s, but this is unlikely to significantly impact activities.

Temperatures are expected to drop to around 8 degrees Celsius in the evening and overnight, with conditions clearing to mostly sunny. For activities after sunset, a headlamp and ample warm clothing are essential.
