What to expectTaipei through the year

Taipei has a clear annual cycle: average daily highs run from 18 °C in January to 31 °C in July, a swing of 13 °C in mean temperature across the year.

Counted across a normal year, 189 days a year reach 25 °C, 77 of them reach 30 °C. The warmest reading in the 1991–2020 record is 38 °C, in July.

Rain is strongly seasonal. August averages 299 mm against 86 mm in January — 3.5 times as much. Planning around the dry months matters more here than planning around temperature.

The sea off Taipei is warmest in August at 29 °C and coldest in February at 18 °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.
