大山快晴続く 稜線は日本海からの風に注意

The Daisen summit currently reports clear skies with a temperature of 3.6℃ and a feel-like temperature of 0.1℃ at 07:30. The significant temperature difference of nearly 6℃ between the summit and base highlights the need for robust cold weather gear as elevation increases for anyone starting their ascent.

Clear skies are expected to persist throughout the day, with temperatures rising to around 7.7℃. However, northwesterly winds are forecast to reach gusts of up to 11.9 m/s by midday. This strong wind will significantly lower the perceived temperature, potentially bringing it below freezing on exposed sections of the Summer Trail leading to Misen and along the main ridges. A windproof outer shell is essential, especially where winds from the Sea of Japan directly impact the terrain. Layering should include a wicking base layer, a fleece mid-layer, and a waterproof/windproof outer shell.

Ground conditions are generally dry, with no snow accumulation, so crampons or microspikes are not required. Nevertheless, be aware of potential frost in shaded or damp areas during early mornings. To prevent hypothermia during breaks, layer with an insulating mid-layer like a light down jacket or fleece, and ensure you have gloves and a hat. While the risk of lightning is low, strong winds pose a risk of losing balance and increasing the risk of hypothermia.

Clear conditions will continue into the night, but temperatures will drop to around 2℃. While climbing is feasible with proper cold weather gear and wind protection, caution is advised due to strong gusts that could affect balance. The traverse towards Kengamine remains closed due to landslides.
