初夏の日差しと風。雲海テラスは防風着を

At 7 AM, the summit of Tomamu is clear with a temperature of 11.8°C, while the base is a milder 15.6°C. Winds at the summit are expected to gradually pick up throughout the day, reaching 4.72 m/s with gusts up to 11.4 m/s by noon, and potentially 12.7 m/s by 3 PM. These strong gusts can drop the perceived temperature near 0°C, necessitating ample cold weather gear to mitigate the risk of hypothermia, even in summer.

Ground conditions are generally dry due to no precipitation and warmer daytime temperatures. However, areas around the Unkai Terrace, accessible by gondola, will be particularly exposed to the wind. While visibility is excellent, allowing for expansive views, ensure you are adequately dressed to avoid chilling. A base layer, a mid-layer such as fleece, and a windproof and waterproof shell jacket are essential. Light gloves and a hat will also provide valuable protection against the wind.

The risk of thunderstorms is low, though partly cloudy conditions are expected on the summit in the afternoon. Always carry full rain gear, including separate jacket and pants, as mountain weather can change rapidly. Stay hydrated during your activity and monitor your physical condition closely.

Winds will persist into the evening, and temperatures will drop to single digits. Avoid activities after sunset and plan to descend early.
