Jakarta, ThedailyID — Only 7.8 percent of Indonesia’s regions have entered the dry season as of early April 2026, according to the BMKG.
The agency shared the update on Tuesday, April 21, 2026, through its official Instagram account. It explained that most parts of the country are still in a transitional phase between wet and dry seasons.
“April is still a transition phase. Only 7.8 percent of Indonesia has entered the dry season so far,” BMKG stated. “The rest are still in the rainy season, so it’s normal if rain still occurs.”
The 7.8 percent figure includes several zones across the country. These consist of 7 ZOM in Bali and Nusa Tenggara, 3 ZOM in Java, 2 ZOM in Kalimantan, 5 ZOM in Maluku and Papua, as well as 19 ZOM in Sulawesi and 19 ZOM in Sumatra.
BMKG also clarified that the dry season does not mean zero rainfall. Instead, rain can still occur, but with lower frequency and intensity.
“The dry season is defined when rainfall is below 50 mm per 10 days for three consecutive periods,” the agency explained.
Moreover, BMKG said the dry season is influenced by the Australian monsoon. This wind pattern moves from south to north across Indonesia, making the transition gradual.
As a result, southern regions such as East Java, Central Java, Bali, NTB, and NTT are expected to enter the dry season earlier, between April and May.
In addition, BMKG addressed circulating claims that the 2026 dry season could be the worst in 30 years. The agency clarified that while conditions may be drier than normal averages, it does not indicate an extreme record-breaking drought.
Therefore, BMKG urged the public to stay informed through official forecasts. Weather conditions may still change during this transition period.
