北岳 穏やかな晴天。濡れた岩場に滑落注意

Mt. Kita summit at 7:45 AM shows mostly clear skies with a temperature of 2 degrees Celsius, feeling like minus 1.1 degrees Celsius due to a light breeze. The forecast indicates mostly clear conditions throughout the day, with temperatures rising to 5.7 degrees Celsius by noon. Winds will remain gentle, with gusts not exceeding 7.2 meters per second, making for a generally favorable day for climbing. The temperature difference between the summit and Hirogawara base is approximately 10 degrees Celsius.

The ground is exposed rock with no snow cover. No precipitation is expected, suggesting dry conditions. However, vigilance is crucial in shaded or damp rocky sections, such as around Happonba-no-Koru, where early morning ice cannot be entirely ruled out. Ensure secure footing to prevent slips and falls. Crampons or microspikes are not necessary, but rain gear should be carried for wind protection.

With wind chill potentially dropping below freezing, proper layering is essential: a wicking base layer, a fleece or light down mid-layer, and a windproof and waterproof shell as an outer layer. Adjust layers frequently to regulate body temperature. Gloves and a hat are also mandatory. Temperatures will drop rapidly after sunset, reaching around 1 degree Celsius at night, so be prepared for hypothermia if your activity extends into the evening. Risks of thunderstorms and strong winds are low.
