Forecast notes
Forecast table times: UTC.
Coordinates: 36.6982934°N, 137.8387784°E · Requested elevation: 749 m. Model terrain: 1407 m. Terrain and 1000/925/850/700 hPa profiles are used for height estimates.
Outside the available profile, temperature uses an estimated 5.5°C/km height correction; wind retains the nearest available model-level value. Humidity is estimated with adjusted pressure and temperature.
These are altitude estimates, not a simulation of local mountain terrain. Precipitation, cloud and sea-level pressure use horizontal interpolation only.
Precipitation includes rain and snow water equivalent: preceding 3 hours through day 6, then 6 hours (see cell tooltip). Snow (cm) estimates fresh snowfall from precipitation and temperature using the GFS conversion; it is not snow depth on the ground. Freezing (m) uses additional 600/500 hPa temperatures when available and estimates the lowest resolved 0°C crossing above sea level. When all sampled levels are warm, the upper profile limit is shown (see tooltip). < marks an entirely cold sampled profile and its lower height limit. No extrapolation is used.

Hakuba Happo-one is a ski area in Nagano, with courses that hosted alpine events during the 1998 Winter Olympics. The official trail guide distinguishes the Olympic courses from learning areas and other runs. Its upper lifts reach approximately 1,830 m, giving a very different mountain setting from the lower access points.
The Olympic name is part of the area’s history, not a difficulty rating for every piste. Choose a route from the current trail guide, including any easier alternative indicated there. For a group with different abilities, agree on a suitable meeting area before heading up rather than assuming everyone will return by the same descent.
The SnowReportMeteo forecast starts at a lower reference of 749 m. For skiing near the upper lifts, select an appropriate elevation and inspect wind and cloud together with the snow forecast. The lower-point temperature alone cannot describe the upper mountain. Compare the forecast with the resort’s current operating information and webcams; an open lower area does not establish that all upper terrain is available.
