What to expectPhan Thiết through the year

Phan Thiết changes little through the year. Average daily highs stay between 29 and 31 °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, 169 of them reach 30 °C. The warmest reading in the 1991–2020 record is 36 °C, in May.

Rain is strongly seasonal. October averages 249 mm against 6 mm in February — 40 times as much. Planning around the dry months matters more here than planning around temperature.

The sea off Phan Thiết is warmest in May at 29 °C and coldest in January at 25 °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.
