What to expectOranjestad through the year

Oranjestad 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, 365 days a year reach 25 °C, 22 of them reach 30 °C. The warmest reading in the 1991–2020 record is 34 °C, in September.

Rain is strongly seasonal. November averages 132 mm against 14 mm in March — 9.6 times as much. Planning around the dry months matters more here than planning around temperature.

The sea off Oranjestad is warmest in September at 29 °C and coldest in February at 26 °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.
