What to expectFuji through the year

Fuji has a clear annual cycle: average daily highs run from 9.5 °C in January to 29 °C in August, a swing of 20 °C in mean temperature across the year.

Counted across a normal year, 99 days a year reach 25 °C, 21 of them reach 30 °C, 13 nights drop below freezing. The warmest reading in the 1991–2020 record is 36 °C, in August.

Rain is strongly seasonal. July averages 296 mm against 98 mm in December — 3.0 times as much. Planning around the dry months matters more here than planning around temperature.

The sea off Fuji is warmest in August at 27 °C and coldest in February at 15 °C. Sea temperature lags the air by a month or two, which is why late summer swims warmer than early summer at the same air temperature.
