What to expectMataram through the year

Mataram 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, 136 of them reach 30 °C. The warmest reading in the 1991–2020 record is 35 °C, in October.

Rain is strongly seasonal. January averages 305 mm against 8 mm in August — 39 times as much. Planning around the dry months matters more here than planning around temperature.

The sea off Mataram 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.
