What to expectJakarta through the year

Jakarta 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, 151 of them reach 30 °C. The warmest reading in the 1991–2020 record is 37 °C, in October.

Rain is strongly seasonal. January averages 300 mm against 44 mm in August — 6.7 times as much. Planning around the dry months matters more here than planning around temperature.
