What to expectSingkawang through the year

Singkawang changes little through the year. Average daily highs stay between 28 and 30 °C, so no month stands out as a season in the way it would further from the equator.

Counted across a normal year, 365 days a year reach 25 °C, 72 of them reach 30 °C. The warmest reading in the 1991–2020 record is 34 °C, in August.

Rain is strongly seasonal. November averages 394 mm against 165 mm in August — 2.4 times as much. Planning around the dry months matters more here than planning around temperature.

The sea off Singkawang is warmest in May at 30 °C and coldest in February at 28 °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.
