Climate Chart of Hakuba, Japan

Climate overview

Temperature

The monthly mean temperature is lowest in January, at -2.3 °C, and highest in August, at 22.8 °C. These are monthly averages, not daytime highs or lows, so they describe the broad temperature character of each month rather than the range visitors may experience from day to day. The unweighted mean across monthly means is 10.3 °C; it is a summary of the calendar-month averages, not a day-weighted annual average.

Snow

Mean daily snowfall is highest in January, at 42.99 mm/day. The unweighted mean across monthly daily snowfall averages is 11.90 mm/day. These amounts describe average daily snowfall, not monthly totals; they do not establish how many days have snow, snow depth or snow cover, and cannot by themselves indicate skiing conditions.

Rain

Mean daily rainfall reaches its monthly high in July, at 8.49 mm/day, while the monthly low is in January, at 1.15 mm/day. These figures are daily averages, not monthly rainfall totals, and a lower mean does not guarantee rain-free days or indicate how frequently rain occurs. The unweighted mean across monthly daily averages is 4.69 mm/day, offering an overall reference rather than a forecast for a particular visit.

Sunshine

Average daily sunshine is highest in August, at 9.73 hours/day, and lowest in December, at 6.04 hours/day. These are mean sunshine hours, not measures of daylight length, and actual conditions can differ from the monthly average. The unweighted mean across monthly sunshine averages is 8.08 hours/day, which provides a broad reference for comparing the months rather than a guarantee of clear skies.
