霧雨で足元滑りやすい。岩場区間は慎重に

Currently, the summit of Mt. Tsukuba is cloudy with a temperature of 15.3 degrees Celsius and an extremely high humidity of 99 percent. The temperature difference from the base is 3.8 degrees Celsius. Intermittent drizzle is forecast throughout the day, with slightly heavier drizzle expected around 9 AM and noon. Temperatures will remain around 15 degrees Celsius, and while the wind is generally light, gusts may reach up to 5.9 meters per second at times.

The ground will be wet due to the continuous drizzle and high humidity. Particular caution is advised on the rocky sections, such as those found on the Miyukigahara Course and Shirakumobashi Course, where peculiar rock formations make footing slippery. The risk of falls and slips is elevated, so choose your steps carefully and avoid putting weight on unstable rocks. Waterproof and breathable rainwear is essential. To prevent hypothermia from getting wet, ensure proper layering with a quick-drying base layer and a thin fleece or similar mid-layer.

While there is no significant risk of thunderstorms or strong winds, continuous exposure to drizzle can lower your perceived temperature. The risk of hypothermia increases if you remain wet, so manage your body temperature diligently with frequent breaks and changes of clothing. Visibility is currently good at 9.4 kilometers but may temporarily decrease during periods of heavier drizzle.

Drizzle will continue into the evening, with temperatures gradually dropping to around 13 degrees Celsius. Avoid prolonged stays near the summit and plan for an early descent.
