What to expectMaracanaú through the year

Maracanaú changes little through the year. Average daily highs stay between 30 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, 365 days a year reach 25 °C, 222 of them reach 30 °C. The warmest reading in the 1991–2020 record is 35 °C, in February.

Rain is strongly seasonal. April averages 214 mm against 5 mm in September — 46 times as much. Planning around the dry months matters more here than planning around temperature.

The sea off Maracanaú is warmest in April at 29 °C and coldest in August at 27 °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.
