日中は快晴で高温。奇岩怪石の岩場はドライ。

This morning, the summit of Mt. Tsukuba is cloudy with a temperature of 12.2°C and 98% humidity, giving a damp feel. The temperature difference from the base is 4.1°C. Clear skies are expected through the day, with temperatures rising to 21.5°C by noon and up to 23.7°C in the afternoon. Winds will remain light throughout the day, with gusts peaking around 5.9 m/s, posing no significant challenge to your ascent.

Ground conditions are dry. The rocky sections of routes like the Miyukigahara Course and Shirakumobashi Course, known for their unique rock formations, present a low risk of slipping. However, the rapid increase in daytime temperatures elevates the risk of heatstroke, a common concern for Mt. Tsukuba in summer. Consistent and frequent hydration is crucial throughout your hike.

For layering, a light fleece or wind shell might be useful in the early morning at higher elevations, but a base layer will likely suffice for most of the day as temperatures climb. Adjust your layers frequently to manage body temperature and prevent excessive sweating. While rain gear is not essential for daytime activities, as light rain is only forecast for late evening and overnight, carrying a waterproof and windproof outer shell is still recommended as a general precaution against unexpected mountain weather changes.

Temperatures will hover around 15°C overnight, with light rain beginning after midnight. Risks of hypothermia and strong winds are low for today's daytime ascent.
