Cyclone 90S Approaches Bali, Heavy Rain and Strong Winds Expected 2-8 March

The Meteorology, Climatology and Geophysics Agency (BMKG) Region III Denpasar has identified the potential for extreme weather in Bali during the period 2-8 March 2026. This extreme weather could result in increased rainfall intensity across most of Bali’s regions.

Since Monday morning (2 March 2026), heavy rain has fallen on Denpasar city. As a result, several road sections have been flooded, including Teuku Umar Street.

Cahyo Nugroho, Head of BMKG Region III Denpasar, presented the findings of the extreme weather analysis, attributing it to a pattern of air mass convergence around the Bali region.

“Additionally, the activity of the Madden-Julian Oscillation (MJO) in phase 4 (Maritime Continent) can provide a significant contribution to the formation of rain clouds,” said Cahyo on Monday (2 March 2026).

Furthermore, Cahyo continued, Cyclone 90S, currently located in the waters south of the southwestern Indian Ocean near Banten, is showing a movement pattern eastward towards the waters south of Bali. This pattern has the potential to cause high rainfall and strong winds.

“This condition is also supported by equatorial Rossby and Kelvin waves, which are predicted to traverse the Bali region in the coming days,” added Cahyo.

BMKG has mapped all regencies and municipalities in Bali as potentially experiencing extreme weather with heavy rain accompanied by strong winds that could cause flooding, flash floods and landslides, depending on the vulnerability level of each region.

Cahyo also urged residents in coastal areas to be cautious of high ocean waves ranging from 1.25-3.5 metres in the southern Bali Strait, Badung Strait, southern Lombok Strait and southern Bali waters.
