湿潤な岩場に足元注意。午後から晴れ間

Currently, Mount Tsukuba summit reports cloudy skies with a temperature of 16.1°C and 99% humidity. Visibility is low at 1km. Winds are calm at 0.8m/s, but the high humidity necessitates caution against chilling from sweat. The temperature difference from the base is 3.7°C, making the summit area feel cooler. For daytime activities, wear a quick-drying base layer, a thin fleece mid-layer, and carry a waterproof-breathable outer shell. This shell will be crucial for maintaining body temperature during breaks or in windy spots.

Trail conditions are expected to be wet due to high humidity, morning dew, and fog. Although the chance of rain is low, the risk of slipping on rocky sections is elevated. Particular care is required on the Miyukigahara Course and Shirakumobashi Course, which feature numerous unique rock formations. Wear appropriate non-slip hiking boots and pay close attention to your footing, especially on descents. Using trekking poles can also be beneficial.

The risk of thunderstorms is low, and gusts during the day will not exceed approximately 5.8m/s, posing no significant hindrance to activity. While the direct risk of hypothermia is low, the high humidity can lead to chilling from sweat and drain energy. Regulate your body temperature by adding or removing layers as needed. Conditions are expected to clear towards evening, with visibility improving. However, temperatures will drop to 14°C overnight, so day hikers must ensure they descend before sunset.
