2026 Dry Season Predicted to Start from April, Bali-Nusra to Begin Earlier
The onset of the 2026 dry season in Indonesia is predicted to occur gradually starting from April. This forecast aligns with the analysis from the Meteorology, Climatology, and Geophysics Agency (BMKG). This information is vital for the public to prepare for agricultural activities, water availability, and anticipating dry weather.
Based on the book Prediction of the 2026 Dry Season in Indonesia issued by BMKG, the start of the 2026 dry season will occur gradually across various regions. Most of Indonesia is expected to enter the dry season during the April, May, and June 2026 period, beginning in Nusa Tenggara (Nusra) and then expanding to other areas.
Cited from detikNews, referring to the BMKG publication, around 114 Seasonal Zones (ZOM) or 16.3% of the area are predicted to start the dry season in April 2026, followed by 184 ZOM in May and 163 ZOM in June. This prediction indicates a gradual seasonal transition that does not occur simultaneously across all of Indonesia.
BMKG notes that regions predicted to enter the early dry season in April 2026 include the northern coast of western Java, the northern and southern coasts of Central Java, most of the Special Region of Yogyakarta, parts of East Java, parts of Bali, West Nusa Tenggara (NTB), East Nusa Tenggara (NTT), and a small part of South Sulawesi.
Overall, the onset of the dry season in Indonesia does not occur simultaneously. From a total of 699 ZOM, a small portion of regions will already start the dry season from February and March, while other areas will enter the dry period in subsequent months. This shows the differing climate characteristics in each region of Indonesia.
BMKG also predicts that most of Indonesia will experience the onset of the dry season earlier than normal conditions. Around 46.5% of the area is expected to have an earlier dry season compared to the 1991-2020 climatological average.
Additionally, the peak of the dry season is forecasted to occur from July to September 2026, with most regions experiencing drier conditions than normal. This information serves as an important reference for the agriculture, water resources, energy, and disaster sectors in preparing anticipatory measures against potential droughts.
BMKG’s 2026 dry season prediction can be used as a reference by the public and local governments in facing the dry period starting from April. By understanding the regions that enter the dry season earlier, anticipatory steps such as water management and activity adjustments can be taken in advance.
