What to expectMacapá through the year

Macapá changes little through the year. Average daily highs stay between 28 and 32 °C, so no month stands out as a season in the way it would further from the equator.

Counted across a normal year, 363 days a year reach 25 °C, 133 of them reach 30 °C. The warmest reading in the 1991–2020 record is 34 °C, in November.

Rain is strongly seasonal. March averages 389 mm against 18 mm in October — 22 times as much. Planning around the dry months matters more here than planning around temperature.

The sea off Macapá is warmest in October at 30 °C and coldest in March 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.
