Reading the seasons
Station
JMA's Nozawa Onsen AMeDAS station (block 0393) stands at 576 m beside Nozawa Onsen village in Nagano. The ski area's lifts rise above it, so the upper slopes run colder than these figures. Nozawa has its own normals, so this file uses them in place of Iiyama's. Every value is JMA's 1991–2020 normal.
Winter
January averages 366 cm of new snow and 253.5 mm of precipitation, with 1 mm or more falling on 22.1 days. The normal deepest snow reaches 199 cm in February. Daily highs in the village average 1.7 °C in January and 2.6 °C in February.
Spring
April's normal deepest snow drops to 77 cm, and the valley is clear of snow by May. May is the sunniest month at 205.8 hours, with highs of 20.8 °C.

What does JaPow mean?
JaPow is skier slang for Japan's powder snow, a blend of Japan and pow. The snow comes from cold northwesterly winds that cross the Sea of Japan and unload on the mountains facing it, with January the snowiest month at every JMA station we keep near a ski area.
