BeritaBali reports that Bali’s rainy season is predicted to start later than usual. While the rainy season typically begins in early October, most parts of Bali were still experiencing the dry season as of late October 2026.
Aminudin Al Roniri, Head of the BMKG (Meteorology, Climate, and Geophysics) Station in Bali, stated that the rainfall recorded in several areas last weekend does not yet meet the criteria to qualify as the official start of the rainy season. Further monitoring of rainfall levels is required over the coming twenty-day periods.
“As of today (26 October), while some areas in Bali did receive rain last Saturday and Sunday, the intensity does not yet meet the criteria for the onset of the rainy season. Therefore, we need to continue monitoring rainfall levels over the next two ten-day periods,” said Aminudin Al Roniri, Head of the BMKG Climatology Station in Bali, on Monday, 26 October 2026.
Aminudin explained that the rainy season does not begin at the same time across Bali. Each region is expected to enter the rainy season at different times, depending on local weather conditions and rainfall patterns.
“According to our projections, the central part of Bali will enter the rainy season between mid-to-late November. Meanwhile, most areas in western, northern, eastern, and southern Bali are expected to enter the rainy season sometime in December,” he explained.
Although the start of the rainy season is predicted to be delayed this year, the BMKG anticipates that the overall nature of the rainy season in Bali will remain within the normal to above-normal range. Consequently, the public is advised to stay informed as the season transitions. “Regarding the intensity of rainfall for the upcoming rainy season, forecasts indicate that for the Bali region, it will likely range from ‘normal’ to ‘above normal,’” he stated.
Amid the ongoing dry season, the BMKG (Meteorological, Climatological, and Geophysical Agency) has urged the public to be mindful of clean water availability, particularly in drought-prone areas. Land fires are also a risk as long as these dry conditions persist.
“Given that the dry season is still underway across most parts of Bali, the public needs to prepare for potential issues regarding clean water access and the risk of land fires—especially in areas frequently affected by drought. Furthermore, people should remain alert to the possibility of sudden weather shifts as we approach the transitional period (inter-seasonal phase),” he advised.
