The annual average temperature in the area is 24 °C. The warmest month is September, when the average temperature is around 27 °C, and the coldest is April, at 20 °C. The average annual rainfall is 2802 mm. The wettest month is January, with an average of 538 mm rainfall, and the driest is September, with 8 mm rainfall.
Settlements by people have been created beside the river over time. Also loss of housing close to the river has occurred during severe eruptions from Mount Merapi.
