What to expectPhú Quốc through the year

Phú Quốc changes little through the year. Average daily highs stay between 27 and 29 °C, so no month stands out as a season in the way it would further from the equator.

Counted across a normal year, 362 days a year reach 25 °C, 22 of them reach 30 °C. The warmest reading in the 1991–2020 record is 34 °C, in March.

Rain is strongly seasonal. September averages 396 mm against 27 mm in February — 15 times as much. Planning around the dry months matters more here than planning around temperature.

The sea off Phú Quốc is warmest in May at 31 °C and coldest in January 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.
