九重 晴れ間広がり快適。足元は湿り気注意

The summit is currently cloudy with 1km visibility and a feels-like temperature of 10.4°C. Humidity is 100%. Clearing skies are expected from late morning, with mostly sunny conditions through the day. Temperatures will rise to around 15°C at the summit. The feels-like temperature around noon will be approximately 14°C, making for comfortable hiking conditions. For layering, opt for a fast-drying base layer, a thin fleece mid-layer, and a wind-resistant softshell outer layer for easy temperature adjustment.

Given the current high humidity and forecasted light drizzle overnight, trails such as the Makinoto Pass Trail and areas around Bogatsuru Marsh are likely to be wet to muddy. Exposed rocky sections may be slippery. Crampons or microspikes are not necessary, but rain gear is essential. On ridges like Mimata-yama and Kuju-san, reduced visibility can increase the risk of getting lost due to the monotonous terrain; always verify your position with a GPS or map.

Daytime wind gusts will peak around 9.9 m/s, which is not strong enough to impede movement significantly. However, gusts are expected to strengthen to 14.5 m/s overnight, requiring caution for evening activities. While the risk of hypothermia is low due to mild temperatures, be mindful of sweat chill in high humidity and prepare a change of clothes for post-activity breaks. Always check the latest volcanic activity status.
