Dangerous Waves Predicted At Bali’s Most Famous Beach Resorts This Weekend

Share The Article

Weather warnings are coming thick and fast in Bali this monsoon season. This weekend, the 17-18th of February 2023, more weather warnings have been issued across the province. The Meteorology, Climatology, and Geophysics Agency (BMKG) have urged the public to exercise caution, especially if visiting Bali’s famous beach resort areas or heading out on the ocean for maritime tourism experiences.

Specific weather and wave warnings have been issued for some of Bali’s most famous family-friendly beach resorts. Nusa Dua, Tanah Lot, and Sanur have all been given high wave warnings for 17th-18th February, with more bad weather and strong currents predicted early next week.

The shoreline at both Nusa Dua and Sanur are typically very calm, rarely encountering severe waves. This is partly why both areas have become popular with families on vacation since the shoreline is more often than not safe for children to paddle and learn to swim.

Officials from the Meteorology, Climatology, and Geophysics Agency have warned that waves in Nusa Dua may reach up to 3m in height, in Kuta up to 2m, and in Sanur up to 1.5m. In Tabanan Regency, where Tanah Lot is located, waves are predicted to reach up to 2.5m. Last weekend Sanur Beach and German Beach saw an influx of local visitors as the clouds dispersed for a few hours, and the sea was as calm as can be. The beaches may be significantly quieter this weekend.

Speaking to reporters, the Head of the BMKG in Denpasar, Cahyo Nugroho, said, “BMKG’s appeal to the public, including the general public [and tourists], fishermen, and marine tourism operators, is to be aware of the potential for sea waves that can reach two meters or more around the southern waters of Bali.”

He also warned that a westerly wind will cross the whole of the island, with wind speeds ranging from 5-36 kilometers an hour. Further inland in Bedugul and Kintamani, the BMKG predicts thunderstorms during the day times. Weather warnings and updated forecasts are shared daily on the BMKG Bali social media pages. The Meteorology, Climatology, and Geophysics Agency’s account for Bali can be found on Instagram @bmkgbali.

Early forecasts have also been posted on the BMKG Bali website. The data revealed that Bali will be cloud-covered for most of the day, with temperature highs of 32 degrees celsius in Denpasar. Storms are predicted in Karangasem Regency on Sunday morning.


Travelers are reminded that although some of Bali’s most popular beaches operate a safe-to-swim flag system, the majority do not. Visitors must remember that the absence of a flag does not necessarily mean it is safe to enter the water.


Speaking to reporters earlier this week, one forecaster for the BMKG in Denpsar, Agus Mahendra, explained that Bali has now entered the peak of the rainy season. He explained, “So for this month, most areas of Bali have entered the peak of the rainy season. But there are three areas that have not yet entered the peak season. The estimate is that at the end of February to early March, all areas of Bali will have entered the peak of the rainy season.”


He reiterated the agency’s orders for the public to remain cautious throughout the rainy season. He said, “The public is advised to remain vigilant and careful about the impacts of disasters that can occur. Such as strong winds, fallen trees, lightning, floods, puddles, and landslides. Before doing activities at sea, it is necessary to pay attention to the conditions and warnings regarding weather updates from us so that we can prevent the potential for unwanted things to happen.”
