—
Meteorology, Climatology and Geophysics Agency (
BMKG
) said several weather factors such as Tropical Cyclone Fung-wong, MJO activity, and atmospheric waves were the causes of extreme weather looming over a number of regions in Indonesia in the next week.
BMKG estimates that the potential for rain cloud growth is still significant in various regions of Indonesia.As a result, rain with light to very heavy intensity has the potential to flush a number of areas.
“Several main factors that play a role in the weather dynamics of this period include Tropical Cyclone Fung-wong, Madden-Julian Oscillation (MJO) activity, as well as Equatorial Kelvin and Rossby atmospheric waves which are predicted to be active in Indonesia until mid-November 2025,” said Guswanto in Jakarta, Monday (10/11), according to the official BMKG website.

In the Weekly Weather Prospects for the Period 11 – 17 November 2025, BMKG explained that Tropical Cyclone Fung-wong, which is currently in the Pacific Ocean, could have an indirect impact on the weather in parts of Indonesia, ranging from heavy rain to high waves.
Then, equatorial Rossby and Kelvin atmospheric waves are predicted to be active in most parts of Indonesia, and the MJO which is spatially active in parts of Indonesia includes most of Sumatra, Java and NTB.This phenomenon increases the potential for rain in these areas.
Apart from these three factors, another factor that will have an impact on the country’s weather conditions in the next week is cyclonic circulation.
Cyclonic circulation is predicted to be consistent in the next week in the Indian Ocean west of Lampung to southwest Banten which is able to increase the potential for rain cloud growth along the west coast of Sumatra, southern Sumatra to western Java.
Apart from that, the flow of cold air masses from Asia is also expected to enter Indonesian territory in the next few days.This is said to be able to increase the potential for rain in parts of southern Indonesia.
“By considering these conditions, the public is advised to remain alert to the potential for extreme weather that could cause hydrometeorological disasters such as floods, inundations and landslides, which have the potential to disrupt daily activities and transportation,” wrote BMKG in its weather outlook.
Affected areas
BMKG Director of Public Meteorology Andri Ramdhani predicts the potential for significant extreme weather in most parts of Indonesia in the period 10-16 November 2025.
Based on BMKG analysis, the potential for moderate to heavy rain on November 10-12 has the potential to occur in most of Sumatra, Kalimantan, Sulawesi, Papua, DKI Jakarta, DI Yogyakarta, Bali and Nusa Tenggara.
Meanwhile, the potential for heavy-very heavy rain has the potential to occur in Aceh, Bengkulu, Banten, West Java, Central Java, East Java, West Kalimantan, West Sulawesi, North Maluku, West Papua, Central Papua, Mountainous Papua, Papua, South Papua, West Sumatra, West Nusa Tenggara, East Kalimantan, South Sulawesi and East Nusa Tenggara.
“The potential for strong winds is predicted to occur in the Banten, Bengkulu, Lampung, West Nusa Tenggara and West Sumatra areas,” explained Andri.
Then on 13-16 November 2025, the potential for heavy-very heavy rain will still occur in Bengkulu, West Java, DI Yogyakarta, East Java, West Nusa Tenggara, East Nusa Tenggara, West Kalimantan, Central Kalimantan, South Kalimantan, South Sulawesi, Central Papua and Mountainous Papua.
Furthermore, the potential for moderate-heavy rain still has the potential to occur in Aceh, North Sumatra, West Sumatra, Riau, Riau Islands, Jambi, South Sumatra, Bangka Belitung Islands, Lampung, Banten, DKI Jakarta, Central Java, Bali, West Nusa Tenggara, West Kalimantan, Central Kalimantan, East Kalimantan, North Kalimantan, North Sulawesi, Gorontalo, Central Sulawesi, West Sulawesi, Southeast Sulawesi,North Maluku, Maluku, Southwest Papua, West Papua, Central Papua and Papua.
The potential for strong winds will still occur in Central Java, West Kalimantan, Central Sulawesi, South Sulawesi, Central Kalimantan, South Kalimantan, West Nusa Tenggara, Bali, DKI Jakarta and Banten.
