Jakarta, January 13, 2026 — Extreme weather conditions that have struck Jakarta and Java since the beginning of this week have forced port authorities to temporarily suspend all fast boat operations from Muara Angke Port to the Thousand Islands. This measure was taken as an anticipatory effort to minimize the risk of maritime accidents due to heavy rainfall and dangerous waves.
Ship Operational Status
The Jakarta Transportation Agency (Dishub DKI Jakarta) has suspended fast boat operations since Monday, January 12, 2026, as reported by VOI.id. Head of the Water Transportation Management Unit (UPAP) for Jakarta Dishub, Muhamad Wildan Anwar, stated that this suspension was based on instructions from the Harbormaster and Port Authority Office (KSOP) Muara Angke, which has not issued sailing permits, according to Beritasatu.com.
“Passenger safety is our top priority. We have suspended fast boat operations for two days since Monday to minimize the risk of accidents at sea,” said Wildan, as quoted by Antara News.
At least four fast boat units serving routes to various islands in the Thousand Islands were not permitted to sail during this severe weather period.
Affected Routes
Four main fast boat routes operated by Jakarta Dishub that are temporarily suspended, as reported by Antara News:
- Main Route 1: Muara Angke – Untung Jawa Island – Lancang Island – Payung Island – Tidung Island
- Main Route 2: Muara Angke – Untung Jawa Island – Pari Island – Panggang Island – Pramuka Island
- Main Route 3: Muara Angke – Pari Island – Pramuka Island – Kelapa Island
- Main Route 4: Muara Angke – Kelapa Island – Sabira Island
Weather Conditions and BMKG Forecast
The Meteorology, Climatology, and Geophysics Agency (BMKG) reported the potential for extreme weather in the form of heavy to very heavy rain accompanied by strong winds likely to occur until January 15, 2026, according to Bisnis Jakarta. In the DKI Jakarta area, heavy to very heavy rain is expected on January 13, while on January 14-15, rain is still likely to fall with moderate to heavy intensity.
BMKG Head, Teuku Faisal Fathani, previously predicted that the peak of the rainy season in southern Sumatra, Java, Bali, and Nusa Tenggara would occur in January 2026, as cited by Kompas.com. This condition is triggered by the presence of several tropical cyclones surrounding Indonesia and inducing high rainfall in various regions.
BMKG coordinates with Airnav Indonesia and KSOP to ensure weather conditions for aviation and maritime operations. When weather is severe, aircraft and ships are prohibited from operating temporarily, as reported by Kompas.com.
Coordination and Anticipatory Measures
Wildan added that Jakarta Dishub continues to coordinate intensively with KSOP Muara Angke regarding weather developments and maritime safety, according to Beritasatu.com. “Ship operations will reopen after sailing permits are issued and weather is declared safe,” he said.
The suspension policy was based on weather data from BMKG and field condition evaluations showing high sea waves and low visibility due to heavy rain, as reported by VOI.id. To date, no significant passenger congestion has been reported at Muara Angke Port following early socialization conducted by officers at the location.
Operational Recovery
On Thursday, January 15, 2026, the Jakarta Provincial Government reactivated fast boat services to the Thousand Islands after obtaining sailing approval from KSOP, according to Ipol.id. However, not all routes were immediately reopened. Of the four main routes normally served, only three routes were declared safe for operation.
“As of today, Dishub fast boats have officially received sailing permits from KSOP,” said Wildan, as quoted by Ipol.id.
Public Advisory
Prospective passengers are advised to postpone their trips or seek the latest information through official Jakarta Dishub channels before heading to the port. Authorities also urge the public to always monitor weather developments and follow instructions from port officers for collective safety.
The primary priority of authorities at this time is to prevent the risk of maritime accidents due to high waves and low visibility triggered by heavy rain in Jakarta Bay and surrounding areas.
