Speaking after the 2025 Forest and Land Fire Control Exposure event at the Ministry of Forestry office in Jakarta, BMKG Deputy for Meteorology Guswanto explained that the ideal maximum temperature in urban areas typically ranges between 31 and 34 degrees Celsius.
“Why does it feel so hot right now? Because the Sun has shifted to the southern part of Indonesia,” he said.
This solar shift has also reduced the formation of rain clouds in the southern regions. With minimal cloud cover, there is little to block the Sun’s intense radiation, causing the heat to feel stronger on the surface.
As a result, temperatures in several parts of Indonesia have risen noticeably in recent days.
On rainfall patterns, Guswanto noted that Indonesia officially entered the rainy season in August. However, due to the country’s wide geographical range, the onset of the rainy season varies across regions.
BMKG forecasts indicate that nearly all parts of Indonesia will enter the rainy season by November. The agency also warned of potential extreme weather over the coming week in several areas, including North Sumatra and Central Java.
“By December, January, and February, the rainy season will occur simultaneously across the country,” he added.
Earlier BMKG reports showed that high temperatures were recorded in several cities on Monday (October 13), ranging from 27 to 35 degrees Celsius. Cities such as Serang, Semarang, Yogyakarta, and Surabaya experienced temperatures between 32 and 35 degrees Celsius.
