蔵王午前はガスの中。稜線は防寒必須。

Zao summit currently experiences cloudy conditions with visibility below 1 kilometer. The temperature is 3.6°C, feeling like 1°C, with a light wind of 2.06 meters per second and high humidity at 99%. This morning, areas around Kumano-dake and the ridge from Katta-dake to Kumano-dake will remain shrouded in fog, causing poor visibility. While not a full whiteout, caution is advised to prevent accidental contact or straying off route, especially where tourists may be present. The significant 7.2°C temperature difference from the base indicates winter-like conditions persist at the summit.

For daytime activities, proper cold weather layering is essential to mitigate the risk of hypothermia. Wear a wicking base layer, a mid-layer such as fleece or light down, and a waterproof-breathable outer shell. Waterproof gloves and a hat are also necessary. The ground is snow-free and ranges from dry to wet; however, high humidity makes rocks and wooden paths slippery. Crampons or microspikes are not required.

Visibility is expected to improve by noon, turning mostly clear by 3 PM, with temperatures rising to 9.5°C. Winds will remain light throughout the day, with maximum gusts around 6.2 meters per second, posing no strong wind hazard. However, strictly observe the crater entry regulations around Okama, even as visibility improves. The evening will be clear with temperatures around 6°C, but nighttime activities are not recommended.
