Tourists visiting Bali’s southern coast this week must be extra aware of their surroundings. While the height of the rainy season always brings the risk of extra high waves, with this week’s full moon impacting the ocean, the risk of tidal swells is dramatically increased.
The Bali Meteorology, Climatology, and Geophysics Agency has issued early warnings for tidal swells, tidal flooding, and high waves. The weather warning is in place until 4th February, and impacts the southern coasts of Tabanan Regency, Badung Regency, Denpasar City, Gianyar Regency, Klungkung Regency, Karangasem Regency, and Jembrana Regency.
In perhaps more familiar terms, this includes top vacation destinations like Canggu, Smeinyak, Legian, Kuta, Jimbaran, Uluwatu, Ungasan, Kutuh, Nusa Dua, Sanur, Kermas, Candidasa, as well as Soka Beach, Balian, and Medewi.
The Head of the Bali BMKG told reporters, “The Full Moon phenomenon on February 2, 2026, has the potential to increase the maximum sea level in several coastal areas of Bali.”
He added, “We urge the public to remain vigilant and alert to anticipate the impact of maximum sea levels and to pay close attention to maritime weather updates from the BMKG Region III through its official channels.”

The tidal swells have the potential to impact beachgoers, especially at high tide, as well as tourists who are boarding fast boats and ferries, and taking part in snorkelling and diving activities. Local fishermen, seaweed and salt farmers have also been issued with the same weather warnings as tidal swells could impact their capacity to work safely in the water.
At this time of year, which is just beyond the peak of the rainy season, tidal swells have the capacity to not only bring heightened volumes of water to the shore but also increased trash and ocean debris too. Bali’s Governor Wayan Koster is taking the matter seriously and has responded to President Prabowo Subianto’s warnings about the trash situation on the island’s most popular tourist beaches.
Speaking to reporters, Governor Koster confirmed that he will be creating a Coastal Clean Up Task Force to tackle the issue. He explained, “I will form a task force to guard the beach, so that as soon as trash arrives, it can be cleaned immediately.”
He added, “In December 2025, January and early February 2026, as long as it rains, the waste will arrive from outside the area very quickly due to the strong currents.” While there are clean-up teams from the Badung Regency Government on standby, the response typically takes 2-3 hours to mobilise, which greatly impacts both local communities and tourists’ access and experience of the island’s most famous beaches.
The new Coastal Clean Up Task Force will include officers from the Bali Provincial Government, the Denpasar City Government, and the Badung Regency Government.
Governor Koster explained, “Based on the President’s directive, we will immediately gather the Head of the Environment Agency, the Head of the Regional Disaster Management Agency, the Head of the Education Agency, the Indonesian National Armed Forces, and the Indonesian National Police. Once we return, we will immediately form a task force.”
Tourists traveling to Bali’s southern coast this week, and for the rest of the rainy season, are urged to check in with the latest weather forecast prior to their visit and respond to weather warnings issued by the Bali Meteorology, Climatology and Geophysics Agency accordingly.
