What to expectSitiawan through the year

Sitiawan 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, 54 of them reach 30 °C. The warmest reading in the 1991–2020 record is 33 °C, in August.

Rain is strongly seasonal. November averages 378 mm against 144 mm in July — 2.6 times as much. Planning around the dry months matters more here than planning around temperature.

The sea off Sitiawan is warmest in May at 30 °C and coldest in January at 29 °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.
