El Niño Remains Very Strong, BMKG Warns of Thunderstorms Across Several West Java Regions

For Wednesday (23/9/2026), similar conditions are expected in Bogor Regency and City, as well as Sukabumi Regency.

On Thursday (24/9/2026), the potential for moderate rain with thunder and strong winds is predicted in Karawang Regency and Purwakarta Regency.

Meanwhile, on Friday (25/9/2026), the areas at risk of moderate rain accompanied by lightning or thunder and strong winds include Purwakarta Regency, Cianjur Regency, Sukabumi Regency, and West Bandung Regency.

El Niño Continues to Suppress Rainfall

Nationally, BMKG projects rainfall across most of Indonesia to remain low to moderate, ranging from 0 to 150 millimeters per ten-day period through the second ten-day period of October 2026.

The very strong El Niño phenomenon is a significant factor limiting moisture supply to Indonesia.

This condition hinders optimal cloud formation, allowing dry weather to persist in several areas.

However, atmospheric dynamics during certain periods can still enhance cloud growth and trigger localized rainfall.

Therefore, although rainfall is generally low due to El Niño’s influence, there remains the possibility of moderate to heavy localized rain when atmospheric conditions are favorable.

BMKG Warns of Dry Season Impacts

Amid the possibility of local rain, BMKG urges the public to remain alert to the impacts of the dry season.

Key concerns include reduced clean water availability, drought affecting agricultural land, and an increase in hotspots that could trigger forest and land fires.

"The public is advised to increase vigilance against the effects of the dry season, such as declining clean water supplies, drought in farming areas, as well as a rise in hotspots that may cause forest and land fires (karhutla)," Edi cautioned.
