穏やかな八甲田。湿原散策は快適に

Hakkoda-san will experience mild and generally clear weather throughout the day, transitioning from partly cloudy to mostly sunny. The summit temperature is 12.1°C, feeling like 10.9°C, and is expected to rise to 14.4°C during the day. Winds will remain light, around 1 m/s, with gusts not exceeding 6.1 m/s, making for comfortable conditions. Visibility is excellent at over 20 km, promising expansive views.

There is no snow cover, and the ground is expected to be wet, with some muddy sections, particularly in the marshlands along routes such as from Odake to Sukayu Onsen. Crampons or microspikes are not necessary, but sturdy, slip-resistant trekking shoes are recommended. While there's a temporary high chance of precipitation, the forecast indicates 0 mm of rain, so a lightweight rain shell should be carried as a precaution.

Given the comfortable temperatures, a moisture-wicking base layer, a light fleece as a mid-layer for adjustability, and a wind-resistant shell as an outer layer will suffice. The risk of hypothermia and strong winds is low, but be mindful of cooling during breaks and manage your body temperature through layering.

Clouds will build in the evening, but temperatures will stay around 11-12°C, and winds will remain gentle. A headlamp is essential for any post-sunset activities, and always be aware of potential volcanic gases around Jigokunuma.
