Rainfall in Jakarta Reaches 267 Millimeters per Day, Pramono Reveals

In a press conference following a limited meeting on flood mitigation at the Jakarta City Hall, Friday (1/23), the Jakarta Governor, Pramono Anung, said that heavy rainfall occurred on January 12, 18, and 22, 2026.

The highest peak was on the 18th

Meanwhile, the highest peak occurred on January 18, 2025, reaching 267 millimeters per day.

"The highest peak was on the 18th, at 267 millimeters per day, which is very high. Jakarta rarely feels like that," he said.

Jakarta Extends Weather Modification through January 27

In response to this situation, the Jakarta Provincial Government has decided to extend its Weather Modification Operation (OMC). Originally scheduled to end today, the operation has been extended until January 27, 2026.

Pramono confirmed that he had prepared a budget for the implementation of the OMC for the next month.

"On average, we fly three every day, which means that the weather modification is carried out because the budget is available," he added.

Besides weather factors, Pramono highlighted the issue of water infrastructure. During a direct inspection of the Cakung Lama River this morning, he discovered a narrowing of the river's flow (a bottleneck).

Therefore, he instructed his ranks to immediately carry out river normalization to accommodate high water discharge when extreme weather occurs.

Pramono confirmed that the Jakarta Provincial Government has prepared rapid steps to mitigate the impact of extreme weather and handle flooding.

"We assigned the Regional Secretary to coordinate so that the SOP that we have standardized can be checked more easily and more simply," he stated.
