湿潤な稜線。午後は視界開ける

Current conditions at Tanigawadake summit are cloudy with a temperature of 6.5℃ and a feels-like temperature of 4.6℃. Humidity is extremely high at 99%. There is an 8.5℃ temperature difference between the summit and the base. Temperatures are expected to rise during the day, with conditions becoming mostly sunny by the afternoon. Visibility is also forecast to improve from the current 4.8km.

Despite no precipitation, the ground will remain generally wet due to the high humidity. Expect wet sections and muddy areas, particularly on the rocky ridges and trails after exiting the tree line. Exercise caution on slippery surfaces. For daytime activity, wear a quick-drying base layer, a light fleece or wool shirt as a mid-layer, and carry waterproof-breathable rain gear as an outer layer. An additional light synthetic insulation jacket is recommended for breaks or exposed areas where the feels-like temperature drops. Crampons or microspikes are not needed.

Winds will reach gusts of up to 9.1m/s during the day. While this should not significantly impede movement, the exposed ridges around the Toma-no-Mimi and Oki-no-Mimi twin peaks will be affected by wind. Given Tanigawadake's unique propensity for rapid weather changes and sudden fog due to high humidity, be prepared for abrupt visibility deterioration. Always monitor your map and compass or GPS. The risk of hypothermia persists, so ensure adequate protection from wetness and maintain proper layering. The risk of lightning is low.

Temperatures will drop to around 6℃ from evening into night, with cloudy conditions expected to return. An early return from the mountains is advised.
