Based on the data from 1991 to 2020, the highest average monthly precipitation in Indonesia was in December, at 299.19 millimeters, and the lowest was in August, at 166.9 millimeters.

While there is a significant regional variation, the dry season in Indonesia generally runs from May to September in most of the country (including Java and Bali), and the rainy season runs from October to April.
In Indonesia, there are three types of rainfall patterns: monsoon rainfall, with a monthly rainfall peak in December; equatorial rainfall, with two monthly rainfall peaks in March and October; and localized rainfall, with a monthly rainfall peak from July to August in the eastern equatorial part of the country.
