The national meteorological agency warns of continued volatile conditions, with potential impacts on travel and maritime activities across the island.
DENPASAR, Bali — Indonesia’s Meteorology, Climatology, and Geophysics Agency (BBMKG) has issued a weather advisory for Friday, January 16, 2026, cautioning residents and visitors in specific areas of Bali to prepare for potentially disruptive conditions.
The agency forecasts a high chance of moderate to heavy rainfall in four regencies: Buleleng, Jembrana, Karangasem, and Tabanan. These areas, particularly in northern, western, and eastern Bali, have been prone to landslides and flooding during the current intense rainy season.
Separately, strong winds are predicted for five regions: Badung, Klungkung, Buleleng, Karangasem, and Denpasar City. General conditions across Bali are expected to be cloudy, with wind speeds ranging from 5 to 43 kilometers per hour and a maximum air temperature of 33 degrees Celsius.
Marine Conditions and Port Updates
For maritime travel and activities, wave heights are forecast to be moderate. The northern Bali seas are expected to see waves of 0.5 to 2.0 meters, while southern waters may experience waves of 0.5 to 2.5 meters.
The latest port-specific data from the BBMKG indicates light rain and calm seas at most key harbors, including Benoa, Sanur, Padangbai, and the ports serving Nusa Penida. Thick cloud cover is reported at Gilimanuk and Serangan port, with slightly higher waves of 0.5-1.25 meters at Celukan Bawang and Serangan.
Safety Guidance for Residents and Travelers
This advisory follows a series of significant weather-related incidents across Bali this week, including landslides, flooding, and fallen trees. The continued forecast for heavy rain, particularly in already saturated regions, underscores the need for ongoing vigilance.
For tourists and expatriates in Bali, this is a critical reminder to:
- Plan Travel Carefully: If traveling to or through the affected regencies (Buleleng, Jembrana, Karangasem, Tabanan), check road conditions beforehand and allow for extra time. Avoid mountainous or riverside routes during heavy downpours.
- Be Wind Aware: Secure loose outdoor items and exercise caution in open areas, especially along the coast and in the southern Badung and Denpasar areas where strong winds are forecast.
- Maritime Activities: Those planning sea crossings, particularly on smaller vessels, should confirm conditions with ferry operators. While most port waves are currently low, conditions can change rapidly.
- Stay Informed: Monitor official weather updates from the BBMKG and heed any instructions from local authorities regarding safety.
The agency’s warning highlights the persistent instability of Bali’s weather during the peak of the west season, where localized heavy rain can trigger sudden hazards even when general forecasts appear mild.
