苗場山頂湿原は好天。午後から霧雨に備えよ

Today, Naeba-san will experience generally clear and mild weather in the morning, making for a comfortable hiking day on the summit plateau. The current summit temperature is 15.7℃, expected to rise to between 17℃ and nearly 20℃ during the day. Winds will remain light throughout, ensuring a pleasant perceived temperature. Current visibility is a good 5.4km, but a brief period of light drizzle (0.2mm precipitation) is forecast around 3 PM.

Although there has been no significant precipitation so far, the high humidity means that the wooden boardwalks within the extensive summit plateau wetlands may be damp and slippery. While not muddy, caution is advised for foot placement. It is strictly prohibited to step off the boardwalks to protect the delicate wetland ecosystem. Essential gear includes a moisture-wicking base layer, a light mid-layer, and waterproof-breathable outer shell jacket and pants for the afternoon drizzle and high humidity.

The likelihood of lightning is low. Maximum wind gusts are expected to be around 6.2m/s, which is not strong enough to impede movement. With adequately warm temperatures and proper layering, the risk of hypothermia is low. However, getting wet from the drizzle can lower the perceived temperature, so wearing rain gear is crucial, and consider carrying spare dry clothes. Conditions are expected to clear up towards the evening, with mostly clear skies continuing overnight.
