午前は穏やか。午後から雨具必須。稜線は視界不良に注意

Mount Hakusan summit is partly cloudy with an actual temperature of 6.2 degrees Celsius and a felt temperature of 3.9 degrees Celsius at 7:15 AM. There is a significant temperature difference of nearly 10 degrees from the base, indicating considerable cooling with altitude. While a calm ascent is expected this morning with light winds, precipitation probability will rise to a maximum of 90 percent in the afternoon, making rain gear essential.

The ground is predominantly dry with zero snowfall, but given it is late May and still within the residual snow season, caution is advised for snowfields in shaded areas and valleys. Even on main routes like the Sabo Shindo, hard-packed snowfields in the morning may soften with rising daytime temperatures, posing a risk of slipping. Some sections of the trail may become muddy due to afternoon precipitation.

During activity, the felt temperature will range from 7 to 9 degrees Celsius in the morning. However, gusts on the exposed ridges of Mount Hakusan, such as Gozenmine and Onanjimine, could reach up to 9.2 meters per second, further lowering the felt temperature. It is crucial to wear a wicking base layer, a mid-layer like fleece for insulation, and a windproof and waterproof outer shell to prevent chilling during breaks. With the increasing chance of rain in the afternoon, there is also a heightened risk of thunderstorms and dense fog leading to poor visibility on the ridges. Prioritize an early start and be prepared to turn back promptly if there are signs of deteriorating weather.
