What to expectGeneral Santos through the year

General Santos 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, 209 of them reach 30 °C. The warmest reading in the 1991–2020 record is 37 °C, in April.

Rain is strongly seasonal. June averages 308 mm against 149 mm in February — 2.1 times as much. Planning around the dry months matters more here than planning around temperature.

The sea off General Santos is warmest in May at 29 °C and coldest in January 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.
