Weather forecast for Sunday 8 March 2026: BMKG warns of heavy rain from Banten to Papua
BMKG forecast significant weather across a number of Indonesian regions on Sunday, 8 March 2026. The activity of two tropical cyclone seeds around Indonesian waters is expected to increase the potential for convective cloud growth across various areas.
Tropical Cyclone Seed 93S is predicted to be located in the southern Indian Ocean, east of Central Java, and moving westward. The system is expected to trigger the formation of a low-level jet in the southern Indian Ocean near West Java and to create convergence and confluence zones from the southern waters of West Java to Central Java.
In addition, Tropical Cyclone Seed 95W is predicted to remain in the northern Pacific Ocean off Papua, moving westward. This system is expected to generate convergence and confluence zones in the northern Pacific waters from Halmahera to West Papua. The combination of the two systems could enhance the growth of rain clouds around the seed areas and along the convergence zones.
Meanwhile, rain with moderate to heavy intensity is forecast in several other parts of Indonesia.
The public is urged to monitor weather information through the official bmkg.go.id site or the Info BMKG app. This information is important to anticipate the impacts of extreme weather such as floods, landslides, and strong winds. The rapid changes in Batam call for heightened vigilance, especially for maritime and air transport users.
BMKG forecasts thunderstorms in East and North Jakarta on Saturday morning (7 March 2026). Be aware of the potential for strong winds and temperatures of 23–26°C.
BMKG warns of potentially significant rainfall in several regions on Saturday (7 March). The Disaster Mitigation Agency (BPBD) of DKI Jakarta reminds the public to watch for extreme weather in the capital for the coming week. The BMKG also notes that the period 5–8 March 2026 is expected to be dominated by light to moderate rain.
BMKG monitors three tropical cyclone seeds (90S, 93S, 92P) that could trigger extreme weather in Indonesia. Expect heavy rain, strong winds, and waves up to 4 metres.
