Bali’s southern coastline has captured the attention of numerous tourists, but they must now remain alert to tidal flooding. The agency’s warning has noted the risk of coastal flooding in some severely important tourist sites and thus, tourists and local operators must exercise extreme caution.
Tidal Flooding Risks for Bali’s Southern Coast
The BMKG has highlighted the southern coast of Bali as an area of concern due to expected tidal flooding. This warning, which is in effect for several regions across the island, includes popular tourist hotspots such as Tanah Lot, Uluwatu, Kuta, Legian, Seminyak, and Canggu. Areas like Sanur, Serangan, Gianyar, and the Klungkung and Karangasem regencies are also expected to experience tidal flooding in the coming days.

BMKG Warning: Tidal Flooding and High Waves in Bali
The Meteorology, Climatology, and Geophysics Agency (BMKG) has issued warnings for tidal flooding and high wave conditions along Bali’s southern coastline due to the ongoing new moon phase. These conditions are expected to affect several coastal areas, including popular tourist spots such as Tanah Lot, Uluwatu, Kuta, Legian, Seminyak, Canggu, and parts of Sanur and Serangan. The agency has cautioned that tidal flooding could cause disruptions to daily activities, particularly in coastal communities dependent on fishing and seaweed farming. Tourists are advised to stay alert and check for real-time updates, as wave heights of 2.5 to 4 meters are forecasted in certain areas, with accompanying strong winds. Travelers are urged to avoid water activities during high tides and follow all safety recommendations provided by local authorities and transport operators.
Tourist Safety Measures
Tourists visiting Bali’s beaches are strongly advised to exercise caution when entering the water, as tidal swells and floods can occur suddenly, especially along shallow shorelines. Travelers should check with their fast boat or ferry providers for the latest safety protocols before embarking on trips, and adjust travel plans if necessary due to weather-related delays or cancellations.
The island’s tourism industry, particularly boat operators, has recently taken extra precautions in the wake of several boat accidents in the past few months, some of which have been fatal. The Bali Provincial Tourism Office has emphasized the need for tourism operators to prioritize safety measures and adhere to the best practices to ensure the wellbeing of tourists.
Tips for Travelers in Bali During Tidal Flooding Season
If you’re planning to visit Bali in the coming days, especially along the southern coastline, it’s essential to be aware of the potential risks associated with tidal flooding and high waves. Here are some important tips to ensure your safety while enjoying your Bali adventure:
- Stay Updated on Weather Warnings
Keep an eye on the latest weather forecasts and tidal flooding warnings issued by the BMKG. Follow their updates on social media, or check with local authorities for real-time information on sea conditions. Staying informed will help you avoid unsafe areas. - Check with Boat Providers
If you’re taking a boat to nearby islands like Nusa Penida, confirm with your ferry or fast boat provider about any changes in schedules or safety measures. It’s crucial to follow any recommendations or restrictions due to high waves and strong winds. - Avoid Entering the Water During High Tides
With the possibility of tidal flooding, be cautious when swimming or engaging in water sports, particularly along shallow shorelines. Avoid beaches that are known to have rapid changes in water levels during peak tidal periods, especially in the early morning or late afternoon. - Choose Off-Peak Travel Times
If possible, book your boat crossings during non-peak hours, such as early mornings or late evenings, when the weather conditions may be calmer. This can help avoid the busiest travel times and reduce the likelihood of delays caused by weather. - Consult Local Experts
Ask local hotel staff or tour guides for advice on the safest beaches and attractions during periods of tidal flooding. They can recommend the best times to visit specific areas to avoid high tides and ensure your safety. - Plan for Possible Delays
Given the risk of tidal flooding and high waves, be prepared for potential delays in travel plans. Leave extra time when heading back to the Sanur or Padangbai harbors for your return trip. Always allow extra time for unexpected weather disruptions. - Pack Essential Safety Gear
When traveling to the beaches, pack essential items like waterproof footwear, a hat, and sunscreen. For water sports, ensure that you are wearing proper safety gear, such as life vests or helmets, if required. - Be Mindful of Strong Winds and Waves
Strong wind speeds can make activities like fishing or boat rides more challenging. Stay informed about wind speeds and always choose reputable, safety-conscious providers when engaging in water-based activities. - Follow Local Safety Guidelines
Adhere to all local safety guidelines, especially in the wake of recent accidents involving boats. Be mindful of official safety protocols and always listen to the advice of local authorities or tourism operators.
By staying informed, following safety tips, and adjusting your travel plans accordingly, you can ensure a safe and enjoyable visit to Bali, even during this period of high tides and possible flooding. Stay safe and enjoy your Bali vacation responsibly!
