The summit is over 9°C colder than the base, maintaining distinctly chilly conditions compared to the lower elevations. The ground, mainly exposed rock along the trails, is generally dry in the morning. However, the probability of precipitation rises significantly to 57% after 12 PM and reaches a high of 96% by 3 PM. Light rain, or "kirisame," is expected from 6 PM, which will make the typically loose rocks around the Yakushidake crater slippery and treacherous underfoot.
