BMKG: Rainfall remains high during 2026 Eid exodus, flooding alert issued
JAKARTA – The Indonesian Meteorology, Climatology and Geophysics Agency (BMKG) has forecast that rainfall intensity will remain relatively high during the 2026 Eid exodus period, including in the Jakarta region during the first half of March.
This was announced by BMKG Head Teuku Faisal Fathani during a coordination meeting for preparations for Eid al-Fitr 1447 H at the Pearl Auditorium of the Police Science College in South Jakarta on Monday 2 March 2026.
Faisal stated that weather conditions during the pre-exodus and exodus periods still require careful monitoring because March remains within the rainy season.
“Generally, weather during the Eid al-Fitr holiday period is forecast to be dominated by light to moderate rainfall. However, the potential for heavy rainfall still needs to be anticipated in several regions,” Faisal said, citing the official BMKG website.
He explained that in March 2026, rainfall across Indonesia is generally expected to be in the moderate to high category, with the possibility of very high rainfall in several regions such as West Java and Central Java.
During the 1–10 March 2026 period, although weather is dominated by light to moderate rainfall, there is potential for moderate to heavy rainfall in several regions, including Jakarta, Banten and West Java.
Meanwhile, during the 11–20 March and 21–31 March 2026 periods, weather is expected to remain dominated by light to moderate rainfall, though heavy rainfall potential can still occur in some Indonesian regions.
According to Faisal, several atmospheric dynamics remain active in influencing weather conditions during this period.
In addition to the influence of the Asian Monsoon, Madden-Julian Oscillation (MJO) activity and atmospheric waves also contribute to increased rainfall cloud formation.
BMKG is also monitoring the potential formation of tropical cyclone seeds in southern Indonesian waters, including seed cyclone 90S observed in the Indian Ocean southwest of Lampung.
Metro Jaya Police Traffic Director Brigadier Komarudin stated that his unit has mapped several flood-prone points in the Jakarta region and surrounding areas.
“What needs to be anticipated is the weather anomaly and predictions from BMKG, where we are currently in a situation with medium to high rainfall intensity, which needs to be anticipated,” Komarudin said on Monday 9 March 2026.
He said the mapping was conducted so that officers could immediately respond if water accumulation disrupted vehicle flow.
