JAKARTA - The Meteorology, Climatology and Geophysics Agency (BMKG) revealed that as much as 10 percent of Indonesia's territory is starting to enter the rainy season.

"Based on the number of season zones, as much as 10 percent of Indonesia's territory falls into the rainy season," said BMKG Climate Analyst Kukuh Prasetyaningtyas, citing Antara.

Kukuh explained that areas currently experiencing the rainy season include parts of Aceh, North Sumatra, most of Riau, most of West Sumatra, Bengkulu, a small part of West Kalimantan, a small part of North Kalimantan, eastern Central Sulawesi, a small part of Maluku and a small part of West Papua.

In September III to October II this year, BMKG predicts rainfall will generally be in the low to medium criteria (0-75 millimeters per season).

Areas predicted to experience low category rain below 50 millimeters per day are most of central to southern Sumatra, Java to East Nusa Tenggara, most of Kalimantan, most of Sulawesi and Maluku, parts of West Papua, northern Papua, and South Papua in basis III September 2023.

In the first half of October 2023, low rain areas include central and southern Sumatra, Java to East Nusa Tenggara, most of Kalimantan, most of Sulawesi, Maluku, North Maluku, parts of West Papua, parts of Papua, parts of Mountainous Papua and South Papua.

Moderate El Nino conditions and positive IOD are predicted to continue until the end of 2023.
