午前は快晴の夏山。午後は霧雨に注意

Daisen summit currently experiences clear skies at 7:15 AM, with a temperature of 18.2℃ and a feels like temperature of 19.9℃, indicating a mild morning. Winds are light at 0.85m/s, making the Summer Trail dry and comfortable for ascent. However, this fair weather will change in the afternoon. While mostly clear until around noon, light rain is forecast for 3 PM with a 100% chance of precipitation. Although the rainfall is minimal at 0.8mm, there is a risk of body cooling if clothes get wet.

For layering, carry a quick-drying base layer, a light fleece or long-sleeved shirt as a mid-layer, and a waterproof and breathable rainwear set (jacket and pants) as an outer layer. Preparing for the afternoon mist and evening temperature drop is crucial to stay dry. The temperature difference from the base is approximately 6℃, making the summit feel cooler. The afternoon mist, combined with humid air from the Sea of Japan, could lead to dense fog around Misen summit, potentially reducing visibility. Early action is therefore recommended.

Ground conditions are dry in the morning, but the Summer Trail will become partially wet after 3 PM due to the light rain. Be cautious of slips on rocky sections and wooden paths. Crampons or chain spikes are not necessary. There is no forecast for lightning, and wind speeds will not exceed 6.1m/s, so strong winds are not expected. While the direct risk of hypothermia is low, getting wet in the mist can lower the perceived temperature, so waterproof measures and timely actions are essential for safety. The Ken-ga-mine traverse route remains closed due to collapse.
