Indonesia is one of the countries with frequencies Extreme weather the highest in the world — The geographical position in the equator, surrounded by oceans, with over 100 active volcanoes makes a laboratory of extreme weather phenomena. From the flood that swallowed thousands of homes in a matter of hours, to the breeze that destroyed villages in Java, extreme weather in Indonesia was not just a natural threat — but the reality of life that needs to be understood and anticipated by every Indonesian.
Key Takeaways
- Indonesia is experiencing all kinds of extreme weather: heavy rain, floods, high winds, nipples, heat waves, and drought.
- BMKG issued extreme weather early warnings via website, BMKG Info apps, and Twitter @ InfoBMKG.
- Extreme weather is increasing in frequency and intensity due to global climate change that is worsening the tropical weather cycle.
- La Niña is harming the extreme weather in Indonesia; El Niño is harming drought and forest fires.
- Initial understanding and readiness is the key to reducing casualties from extreme weather.
Extra Weather Type in Indonesia
| Extreme Weather Type | Highest Territory | Summit |
|---|---|---|
| Heavy rain (> 100mm / day) | All over Indonesia, especially Java and Sumatra West | The monsoon, especially when La Niña |
| Bandang flood | The great DAS of Java, Kalimantan, southern perkwesi | December - March |
| The twister breeze | Central Java, Java West, South Sumatra | Transition Season (October and April) |
| High wave (> 4 m) | Java Sea, Sunda Strait, South Indian Ocean | Western Season (February December) |
| Extreme drying | East Java, NTT, NTB | It's long, especially El Niño. |
| Forest fires. | Kalimantan, Sumatra. | Come here long (July-October) |
The roles of El Niño and La Niña in Extreme Weather Indonesia
The two global climate phenomena that most affect Indonesian extreme weather are El Niño and La Niña. El Niño — The conditions at which the surface temperature of the Pacific Ocean are equatorial hotter than normal — It causes Indonesia to experience a longer, drier, hotter drought. It exacerbated the risk of drought, the landfires of Kalimantan and Sumatra, as well as the water shortages at NTT and NTB.
Instead, La Niña — reverse conditions in which the Pacific is colder than normal — Pushing more water vapor into Indonesia, resulting in a heavier and longer rain season. La Niña increases the risk of flooding, landslides, and extreme weather all over Indonesia especially Java, Sumatra, and Kalimantan.

The way BMKG Prevents Extreme Weather
BMKG operates an extreme early warning system that continues to improve its capacity. This system is integrate data from Doppler weather radar (which can detect the intensity of rain and wind in real time), the Himawari satellite that gives you an image every 10 minutes, and the WRF weather model that runs on BMKG supercomputer. When the system detects extreme weather potential in the next 1- 3 days, the BMKG publishes the "Exstress Weather Warning" which is distributed through websites, media and social media.
Extra Weather Tips in Indonesia · Global Voices
- Enable premature warning notification on the BMKG Info application — Alert was sent automatically when there was extreme weather potential around your location.
- Recognize the evacuation route From home and office — Extreme weather is like a flood and high winds can happen very fast
- Prepare emergency bags (emergency kit) berisi dokumen penting, obat-obatan, air minum, dan makanan untuk 3 hari
- Hindari aktivitas di luar saat peringatan cuaca ekstrem aktif — jangan meremehkan peringatan BMKG meski belum terasa ada tanda-tanda cuaca buruk
- Pantau radar dan siaran radio lokal saat cuaca ekstrem sedang berlangsung untuk informasi terkini dan instruksi evakuasi

General question about Extreme Weather
What is the extreme weather definition according to the BMKG?
BMKG mendefinisikan cuaca ekstrem sebagai kondisi cuaca yang menyimpang jauh dari kondisi normal dan berpotensi menimbulkan dampak negatif terhadap kehidupan manusia dan lingkungan. Secara kuantitatif, hujan sangat lebat (>100 mm/hari), angin kencang (>45 km/jam), gelombang tinggi (>2,5 meter), dan suhu sangat tinggi termasuk dalam kategori cuaca ekstrem yang diwaspadai BMKG.
Do extreme weather in Indonesia happen more frequently?
Ya, data menunjukkan peningkatan signifikan. Menurut BMKG, kejadian cuaca ekstrem di Indonesia meningkat sekitar 40% dalam dekade terakhir dibanding dekade sebelumnya. Perubahan iklim global memperburuk kondisi ini dengan meningkatkan energi dalam sistem atmosfer, sehingga badai dan hujan lebat yang terjadi kini cenderung lebih intens meski tidak selalu lebih sering.
How do I get an extreme weather early alert from the BMKG?
Aktifkan notifikasi di aplikasi Info BMKG. BMKG juga mendistribusikan peringatan dini melalui Twitter @InfoBMKG, website bmkg.go.id, siaran radio RRI, dan SMS massal ke semua operator di wilayah yang terdampak. Selain itu, BPBD di setiap kabupaten/kota juga aktif menyebarkan informasi peringatan dini cuaca ekstrem melalui media sosial dan pesan WhatsApp komunitas.
Do nipples happen in the great city of Indonesia?
Ya, puting beliung bisa terjadi di mana saja termasuk kota besar. Fenomena ini paling sering terjadi di musim peralihan (Oktober dan April) ketika suhu permukaan sangat panas namun massa udara dingin dari atas turun bertemu, menciptakan putaran angin konvektif yang kuat. Jakarta, Bandung, Surabaya, dan Semarang semua pernah mengalami puting beliung yang merusak. Puting beliung Indonesia umumnya berskala lebih kecil dari tornado Amerika namun tetap sangat merusak dalam radius beberapa ratus meter.
What is the extreme weather difference and the hydrometeorological disaster?
Cuaca ekstrem adalah fenomena atmosfer yang menyimpang dari kondisi normal (hujan sangat lebat, angin sangat kencang). Bencana hidrometeorologi adalah dampak dari cuaca ekstrem tersebut terhadap manusia dan lingkungan (banjir, tanah longsor, kekeringan). Tidak semua cuaca ekstrem menghasilkan bencana — tergantung pada kerentanan wilayah dan kapasitas infrastruktur setempat dalam menghadapi kondisi tersebut.
Extreme weather adalah bagian tidak terpisahkan dari iklim tropis Indonesia. Dengan pemahaman yang baik dan kesiapsiagaan yang tepat, dampaknya bisa diminimalkan. Pantau terus Today's weather and 7-day forecast kami, serta selalu aktifkan peringatan dini BMKG.
