雨と霧に包まれる大山。足元と視界に注意

Current conditions on Mt. Daisen summit show light rain, a temperature of 13.2℃, and a feels-like temperature of 12.9℃. There's a 5.9℃ temperature difference from the base. Winds are generally light, but gusts up to 12.3m/s have been observed. Light rain or drizzle is forecast to continue throughout the day, with visibility remaining poor at 2.6km. No significant improvement in visibility is expected.

Due to the ongoing rain and high humidity, the Natsuyama Trail is wet and slippery overall. Muddy sections are anticipated, especially on wooden stairs, rocky areas, and exposed tree roots. When ascending towards Misen, constant attention to foot placement is crucial. Dense fog from the Sea of Japan will likely shroud the summit area for the entire day, severely limiting views and increasing the risk of getting lost.

The feels-like temperature near the summit, even with light winds, hovers around 13℃, but can drop to the low 9℃s during gusts. The risk of hypothermia increases significantly when wet, making waterproof and breathable rain gear essential. Choose a quick-drying base layer and carry an insulating mid-layer like fleece. Waterproof trekking shoes and trekking poles will enhance stability on slippery terrain. Crampons or microspikes are not necessary. While the risk of lightning is low, always be mindful of getting wet and potential body temperature drops, taking frequent breaks and replenishing energy.

Drizzle will persist into the evening, with precipitation gradually ceasing overnight, transitioning to cloudy skies. Temperatures will slowly fall to around 11℃ overnight, and winds will further diminish. For daytime activity, prioritize extreme caution regarding poor visibility and treacherous footing, and avoid any overly ambitious plans.
