苗場山頂台地穏やか。夕方から冷え込み雨へ

Currently, the summit of Naeba-san is cloudy with a temperature of 12.4°C and a feels-like temperature of 9.9°C, indicating calm conditions. There is a 7.4°C difference in temperature between the summit and the base, so warm clothing is essential at the top. While there is no precipitation today, the ground is generally dry. However, the vast wetlands on the summit plateau are consistently damp, and boardwalks may be slippery in places. Strictly avoid stepping off the boardwalks to protect the delicate ecosystem of the ponds and wetlands.

The feels-like temperature will remain around 10°C this morning with light winds. We recommend wearing a quick-drying base layer, a fleece or light down jacket as a mid-layer, and a waterproof-breathable outer shell. Winds will strengthen slightly in the afternoon, with the feels-like temperature dropping to around 9°C by 3 PM. Always carry full rain gear.

An automated risk assessment indicates a rapid temperature drop of 7°C during the forecast period, especially towards the evening. Be prepared for sudden changes by carrying an extra insulating layer from the start. Plan to conclude your afternoon activities early and be ready to turn back promptly.

Conditions will deteriorate overnight. Light drizzle is expected to begin around 9 PM, turning into rain by midnight. Gusts up to 14 m/s are forecasted, and the combination of falling temperatures, precipitation, and wind significantly increases the risk of hypothermia. Nighttime activities are not advisable. No thunderstorms are expected.
