TEMPO.CO, Jakarta - The number of regions experiencing a dry season will increase in the third ten-day period of June 2026. The rainfall tends to be below normal in most parts of Kalimantan, Sulawesi, Maluku, North Maluku, and Papua.
This prediction was delivered by the Meteorology, Climatology, and Geophysics Agency (BMKG) in the Indonesian Rain Potential Period 16-22 June 2026. BMKG stated that the expansion of the dry region is supported by El Nino conditions. "Such conditions support the reduction of rainfall potential in several areas of Indonesia."
Entering mid-June, based on BMKG's monitoring results, the atmosphere in Indonesian regions is showing increasingly dry conditions, especially in the southern regions. The Rainy Days Period in Java, Bali, and Nusa Tenggara has entered the medium (11-20 days) to very long (31-60 days) categories.
According to BMKG, 33.3 percent of the Seasonal Zone area, or 233 out of 700 Zones in Indonesia, has entered the dry season. "This needs attention, especially in regions vulnerable to meteorological drought, decreased water availability, and increased potential for hotter daytime temperatures and colder temperatures at night to morning."
From June 16 to 18, several areas remains under early warnings of heavy to very heavy rainfall. BMKG pointed out Aceh, North Sumatra, Central Kalimantan, West Sulawesi, and North Maluku. However, for the period of June 19-22, BMKG stated that there are no areas with the potential for heavy to very heavy rainfall.
Separately, researchers at the Center for Climate and Atmosphere of the National Research and Innovation Agency (BRIN), Erma Yulihastin, shared information about the rapid warming of the Pacific Ocean, which indicates an El Nino event. She said that the sea surface temperature anomaly in the eastern equatorial Pacific Ocean reached 0.9 degrees Celsius above normal at the beginning of this week.
The increase was recorded from +0.8 degrees in the first week of June. "This value has accelerated from the previous week's 0.6 degrees," said the Professor in the field of expertise in climate and extreme weather research, through an authorized social media account.
Erma's prediction, using modeling techniques developed by BRIN, indicates that a strong El Nino will be reached next month. Then, the peak of drought is expected in August-September. "The 2026 El Nino has a pattern of extreme heat propagation in the subsurface, similar to the 1997 El Nino, and a spatial structure similar to 2015," she said.
As is known, many climate models around the world predict that El Nino this year could grow super strong with sea surface temperature anomalies of more than +2 degrees Celsius.
