BMKG: Weak La Niña Still Detected

Darilaut – The Indonesian Agency for Meteorology, Climatology, and Geophysics (BMKG) stated that a weak La Niña is still being detected.

The weak La Niña is still detected through SOI and Niño3.4 values, which have the potential to increase cloud formation, “especially in the eastern part of Indonesia,” said the BMKG’s Directorate of Public Meteorology.

The BMKG estimates that atmospheric phenomena at various scales, both global, regional, and local, will continue to have a significant impact on the weather in Indonesia.

The Madden Julian Oscillation (MJO) phenomenon is predicted to continue to influence atmospheric conditions in Indonesia in the coming days.

MJO activity is expected to enter phase 3 (Indian Ocean) and can make a significant contribution to the formation of rain clouds in the Indonesian region. Kelvin waves are also predicted to be active in Lampung, Java, Bali, Nusa Tenggara, Southeast Sulawesi, South Sulawesi, North Sulawesi, North Maluku, Maluku, Southwest Papua, and West Papua.

The BMKG said that during the period of February 24 – March 2, 2026, the MJO and Equatorial Waves will strengthen the potential for cloud growth in several regions of Indonesia.

The Equatorial Rossby wave is predicted to be active in Java, Bali, Nusa Tenggara, South Sulawesi, Southeast Sulawesi, South Maluku, and South Papua. These conditions have the potential to contribute to increased convective activity and the potential for rain in these areas.
