夏の稜線は涼風。午後の霧雨に備えよ

Niseko Annupuri summit conditions this morning will see temperatures ranging from 9.5 to 14 degrees Celsius. There is a 6-degree Celsius difference compared to the base, making the summit feel significantly cooler. For layering, wear a quick-drying long-sleeve base layer, followed by a thin fleece or synthetic long-sleeve shirt as a mid-layer. A waterproof and breathable rainwear set (jacket and pants) is essential.

The ground is snow-free, with high temperatures and humidity. Light drizzle is expected in the afternoon, suggesting that hiking trails will be wet to muddy in many sections. When planning access to Niseko Annupuri's exposed ridges, be mindful of reduced visibility due to afternoon drizzle and the risk of hypothermia from getting wet and cooler temperatures. While routes centered on the northwest slopes will be less affected by wind, the ridge lines will experience more direct exposure.

The risk of lightning is low, with a maximum 20 percent chance of precipitation. Significant strong winds are not expected, with gusts peaking at around 7.7 meters per second, posing minimal impact on movement. However, getting wet from the afternoon drizzle increases the risk of hypothermia. Properly wearing rainwear to stay dry will mitigate this risk. While activity is permissible, temperatures will drop as it clears up in the evening, requiring adequate cold-weather gear for any post-sunset activities.
