What to expectGorontalo through the year

Gorontalo changes little through the year. Average daily highs stay between 30 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, 365 days a year reach 25 °C, 144 of them reach 30 °C. The warmest reading in the 1991–2020 record is 37 °C, in April.

Rain is strongly seasonal. April averages 239 mm against 94 mm in August — 2.5 times as much. Planning around the dry months matters more here than planning around temperature.

The sea off Gorontalo is warmest in April at 30 °C and coldest in August at 29 °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.
