霧雨の筑波山 濡れた岩場に細心の注意

Current conditions at Tsukuba summit show light drizzle with a temperature of 12.4°C, feeling like 12.2°C. This is approximately 4°C lower than the base. Light drizzle is expected to continue through the morning, with gusts reaching over 11 m/s by midday. Visibility is limited to 3.7km.
Due to the ongoing rain, all trails are wet and muddy. Particular caution is advised on the technical sections of the Shirakumo-bashi Course and Miyukigahara Course, where numerous unique rock formations and exposed rocky areas become extremely slippery. Ensure you wear hiking boots with excellent grip and maintain careful foot placement.
With a perceived temperature in the low 12s, there is a risk of hypothermia. Essential layering includes a quick-drying base layer, a mid-layer such as fleece, and a waterproof-breathable outer shell. Wet clothing can rapidly reduce body temperature, so monitor your condition closely and be prepared to turn back if you feel unwell.
Precipitation is forecast to cease around 3 PM, transitioning to partly cloudy skies, with clear weather expected by evening. While visibility will improve, the ground will remain wet from the day's rain. Consider delaying your ascent until the weather improves, avoiding unnecessary risks in the morning's wet conditions.
