A list of October 2026 hottest Indonesia, 38th degree temperatures

Until mid-October 2026, Indonesia was dominated by dry and hot conditions due to rainfall caused by combinations of El Nino and positive IOD phenomena. Look at the list of hottest areas of the month.

The Meteorology Climatology and Geophysics (BMKG) recorded the nautical temperature anomaly in the Nino3.4 area in early October reached a very strong category of positive 3.33 degrees Celsius, while the index El Niño- Southern Oscitation (ENSO) period of August-September@@

At the same time, the Index of Ocean Dipole (IOD) is basically listed at a positive number 0.703. El Nino's very strong category is exerted with positive IOD tends to reduce the potential rain cloud in the indonesia region.

As a result, the vulnerabilities of forest fires and land are increasing, especially in areas with no long period of rain. According to BMKG identification, there are 1,297 hot spots all over Indonesia.

"The largest spread recorded in Sumatra is 505 points and Kalimantan is 346 points, following Papua and my Maluku for 330 points. In the meantime, the monitored Arkwesi has 66 points, Southeast Nusa 38 points, and Java 12 points," write BMKG on his official page.

In the midst of the still dry atmosphere, the air temperature is also heating up. The temperature in some areas even reaches over 37 degrees Celsius due to minimal cloud cover so that the sun's radiation reaches the surface of the Earth at maximum.

Here's a list of the hottest areas on October 12-13, 2026:

The BMKG calls the combined El Nino and IOD phenomena that are happening will cause the monsoon of 2026 / 2027 to emerge more backwards than its average climatologist and with its also shorter duration.

"The combination of El Nino and IOD phenomena that are happening simultaneously is worsening and extending the drought period in most parts of Indonesia so that the monsoon is late and it's shorter," says the skid chief of KG Thusu Faisal at the press conference 'Predictions Rain' online on Tuesday (22 / 9).

Further, the BMKG estimates that most of Indonesia will experience the peak of the monsoon of December, January, and February.

"In comparison to normal, the duration of the monsoon 2026 / 2027 in the Indonesian region is predictably shorter than normal in 482 ZOM which covers 51.90 percent of the land area of Indonesia, longer than normal at 60 ZOM, which covers 8.58 percent of Indonesian land, and is normal to 40 ZOM, which includes 5,06 percent of the Indonesian land," said the Deputy Centuary Penthology KGGARdhasena Somawan.
