What to expectKobe through the year

Kobe has a clear annual cycle: average daily highs run from 8.2 °C in January to 30 °C in August, a swing of 22 °C in mean temperature across the year.

Counted across a normal year, 110 days a year reach 25 °C, 32 of them reach 30 °C, 11 nights drop below freezing. The warmest reading in the 1991–2020 record is 37 °C, in August.

Rain is strongly seasonal. July averages 210 mm against 56 mm in January — 3.7 times as much. Planning around the dry months matters more here than planning around temperature.

The sea off Kobe is warmest in August at 27 °C and coldest in February at 13 °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.
