2026 Dry Season Begins, NTB and NTT Become the Initial Affected Regions
Several regions in Indonesia are beginning to enter the dry season in April 2026. What about Bali and Nusa Tenggara (Nusra)?
According to detikNews, the Indonesian Meteorological, Climatological, and Geophysical Agency (BMKG) has recorded a gradual seasonal transition in various areas. It starts in certain regions before spreading across all of Indonesia, including Nusa Tenggara (Nusra).
Information on regions entering the dry season is important for the public as a reference to anticipate dry weather, particularly in the agricultural sector, water resources, and daily activities.
NTB and NTT Become the Initial Affected Regions
BMKG states that parts of Indonesia have entered the dry season in April 2026. Based on the number of Seasonal Zones (ZOM), approximately 7% of Indonesia’s regions or 49 ZOM have been recorded as experiencing the dry season.
“Based on the number of ZOM, 7% of Indonesia’s regions (49 ZOM) are experiencing the Dry Season,” BMKG wrote according to the data update on 31 March 2026.
The regions currently experiencing the dry season include:
a small part of Aceh
a small part of North Sumatra
a small part of Riau
a part of Central Sulawesi
a part of South Sulawesi
a part of Southeast Sulawesi
a small part of West Nusa Tenggara (NTB)
a small part of East Nusa Tenggara (NTT)
a part of Maluku
a small part of West Papua
This data indicates that the dry season is beginning in several regions on a limited basis and not yet evenly across all of Indonesia. BMKG emphasises that the start of the dry season does indeed occur gradually according to atmospheric dynamics and monsoon movements.
Regions Predicted to Enter Dry Season in April
BMKG predicts that the number of regions entering the dry season will increase rapidly in April, reaching 114 ZOM or about 16.3%. This period marks the transition of the Asian Monsoon winds to the Australian Monsoon.
According to the official BMKG website, the start of the dry season will begin in the Nusa Tenggara region and then spread to other parts of Indonesia. After April, 184 ZOM are predicted to enter the dry season in May and 163 ZOM in June 2026.
BMKG explains that the seasonal transition is influenced by changes in monsoon winds, from the Asian Monsoon to the Australian Monsoon, which serves as the main indicator of the start of the dry season in Indonesia.
Predictions for the 2026 Dry Season in Indonesia
BMKG predicts that the 2026 dry season will arrive earlier in parts of Indonesia. As many as 325 ZOM or about 46.5% of the regions are estimated to experience an earlier start to the dry season than normal conditions.
In addition, the accumulated rainfall during the dry season is predicted to be in the below-normal category in most of Indonesia, namely around 64.5% of ZOM. This condition indicates the potential for a drier dry season than usual.
BMKG also estimates that the peak of the 2026 dry season in Indonesia will occur in August across about 61.4% of the regions. Even more than half of the regions are predicted to experience a longer dry season duration than normal, so the public is urged to increase vigilance against the potential for drought and forest or land fires.
The 2026 dry season is estimated to occur gradually from April to mid-year, with drier characteristics in several regions. BMKG advises the public to continue monitoring the latest weather and climate information through official channels to anticipate the impacts of the dry season from the outset.
