Kusatsu Onsen Snow Forecast

Start with the upper-mountain wind and cloud line. Here, a cold front pushing across the divide is the pattern to watch, so the useful question is how cold and calm the next window stays. With a 1450 to 2050 metre elevation band and 600 metres of vertical, the groomers tell the story quickly once the first few laps are done. A seasonal baseline around 7 metres means small clean refills matter more than waiting for a giant number. The swing variable is whether the upper lift can run with enough visibility to make the top worth using. If you are looking beyond the ropes, only chase that angle when the forecast also shows settled wind and stable visibility. Chase it after a cold storm only if the wind eases; if the top is socked in, wait for the next clear window.
