曇り空肌寒さ続く。濡れた足元に注意

Cool and cloudy conditions prevail on Niseko Annupuri summit, with current temperatures at 4.7 degrees Celsius, feeling like 2 degrees. A six-degree temperature difference exists between the summit and base, indicating a notable chill as you ascend. While temperatures are forecast to rise to 8.5 degrees Celsius during the day, gusts up to 9.7 meters per second are expected. This could push the perceived temperature on exposed ridges close to freezing.

There is no snow cover. Despite minimal precipitation, high humidity and daytime warming suggest trails will be wet, with muddy sections possible in shaded areas and gullies. Crampons or microspikes are not necessary, but sturdy footwear is advised for potentially slippery terrain. When accessing the ridge, be mindful of wind exposure which can significantly lower your perceived temperature. Take breaks in sheltered spots and adjust your layering frequently.

The risk of thunderstorms is low. However, light drizzle is forecast for the evening. Although precipitation amounts are minimal, carrying waterproof outer layers is crucial to prevent hypothermia, as getting wet in cool conditions can be dangerous. Essential gear includes a fleece or light down jacket for insulation, along with gloves and a hat. Don them promptly if you feel cold.

Overall, mountain activity is feasible throughout the day. However, persistent cloud cover and lack of sunshine will maintain a generally cool feel. The exposed ridge of Niseko Annupuri can feel significantly colder than expected due to wind chill. Visibility remains good, but always plan your activities with ample buffer to accommodate any unforeseen weather changes.
