BMKG Reveals Reasons It's December but Rain is Still Rare Lifestyle – 1 day ago

Jakarta, CNBC Indonesia – Many people in Jabodetabek complain about hot temperatures and hot weather, even though December is usually synonymous with the rainy season.

In fact, the hot temperatures and scorching weather are not only felt by residents of Jabodetabek, but almost the entire island of Java.

So, what causes the temperature to feel hot even though it is already the rainy season?

According to the Meteorology, Climatology and Geophysics Agency (BMKG), hot temperatures and hot weather during the day do not only occur in Jabodetabek, but also in several areas located south of the equator.

Based on a post on the official Instagram account (@infobmkg), BMKG explained that the activity of low pressure patterns around the South China Sea caused the flow of wet air masses south of the equator to decrease. As a result, the water vapor content becomes low south of the equator, so rain is still rare.

“The low water vapor content south of the equator causes a lack of growth of rain clouds in the Java – Nusa Tenggara region so that intense sunlight reaches the earth's surface in that region,” said BMKG, quoted on Sunday (24/12/2023).

Even though almost all areas of Java and Nusa Tenggara were hit by hot temperatures and scorching weather, in the last week heavy rain still occurred in parts of North Sumatra, West Kalimantan, South Kalimantan, Central Sulawesi and Southeast Sulawesi.

“The cause is the low pressure pattern around the South China Sea, which indirectly forms a pattern of meeting and turning winds which causes an increase in the growth of rain clouds around Sumatra, Kalimantan and Sulawesi,” explained BMKG.

According to BMKG, moderate to heavy intensity rain still has the potential to occur in parts of Sumatra, Kalimantan, Sulawesi, Maluku and Papua.

Predicted Weather Conditions After December 23, 2023

According to BMKG, the low pressure pattern in the South China Sea may continue in the next three to four days.

“It is predicted to tend to weaken, resulting in the potential for increased rainfall in the Java – Nusa Tenggara region starting December 23 2023,” explained BMKG.

Finally, BMKG urges the public to remain alert to the possibility of extreme weather during the Christmas and New Year (Nataru) holiday period.

“Stay alert to the possibility of extreme weather during the 2023/2024 Christmas period,” stressed BMKG.
