What to expectLangsa through the year

Langsa 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, 364 days a year reach 25 °C, 122 of them reach 30 °C. The warmest reading in the 1991–2020 record is 34 °C, in March.

Rain is strongly seasonal. November averages 311 mm against 101 mm in February — 3.1 times as much. Planning around the dry months matters more here than planning around temperature.

The sea off Langsa 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.
