RADAR TULUNGAGUNG – The BMKG predicts early dry season 2026, warning that nearly half of Indonesia’s seasonal zones will enter drought conditions sooner than usual. The Meteorology, Climatology, and Geophysics Agency (BMKG) estimates that 46.5 percent of seasonal zones will shift into the dry season earlier, with the peak expected in August 2026.
The BMKG predicts early dry season 2026 will arrive faster and last longer. Officials urge regional governments and communities to prepare for below-normal rainfall that could disrupt agriculture, reduce water supply, and increase wildfire risks.
When the BMKG predicts early dry season 2026, it sends a strong signal to farmers, policymakers, and businesses. The agency highlights three key points: earlier onset, longer duration, and significantly drier conditions across many regions.
BMKG confirms that the 2026 dry season will begin earlier than its climatological average. This shift will automatically extend the dry period in several provinces.
An earlier transition from the rainy season means communities must adjust planting schedules and water management plans. Farmers who rely on seasonal rainfall need to revise crop cycles to avoid harvest failure.
BMKG also projects that rainfall levels in many regions will fall below normal. Lower precipitation will reduce soil moisture faster and intensify drought conditions during the peak period.
The agency sets August 2026 as the peak of the dry season. During that month, rainfall will likely drop to its lowest level in affected areas, raising concerns about water reserves and agricultural productivity.
BMKG identifies southern Sumatra as one of the most vulnerable areas. Lampung also faces a high probability of experiencing drier-than-usual conditions.
On Java Island, most provinces will encounter below-normal rainfall. Bali, West Nusa Tenggara (NTB), and East Nusa Tenggara (NTT) also fall into the high-risk category.
In Kalimantan, West Kalimantan, Central Kalimantan, and South Kalimantan show strong signals of reduced rainfall. Large parts of Sulawesi share similar projections.
In eastern Indonesia, several areas in Papua, Maluku, and North Maluku may also experience a drier dry season. Although the intensity will vary, the pattern shows a broad geographical spread.
Farmers will likely feel the immediate impact of the early dry season. Reduced rainfall can limit irrigation sources and lower crop yields.
Regional governments must anticipate potential strain on reservoirs and groundwater systems. Urban areas with high population density could face tighter water distribution if rainfall deficits persist.
Extended dry periods also increase the risk of forest and land fires. Provinces with peatland ecosystems remain particularly vulnerable. Authorities need to strengthen fire prevention systems and improve monitoring in high-risk zones.
BMKG stresses that this forecast serves as an early warning. Climate patterns may still fluctuate, but early preparation can reduce potential losses.
BMKG encourages regional leaders to respond proactively. Local governments should optimize irrigation networks, protect water sources, and promote conservation campaigns.
Communities can also support mitigation efforts by using water more efficiently during the transition period. Businesses in agriculture and plantation sectors must adjust operational strategies to cope with longer dry spells.
Indonesia experiences dry seasons every year. However, the projection that 46.5 percent of seasonal zones will shift earlier in 2026 demands stronger coordination between central and regional authorities.
With the peak set for August 2026, stakeholders still have time to prepare. Early action will help maintain food security, protect ecosystems, and ensure stable water supply.
As the BMKG predicts early dry season 2026, preparation becomes the key factor. The sooner authorities act, the better Indonesia can manage the risks of a longer and drier year ahead.
