  • TEMPO.CO, Bandung Meteorology, Climatology, and Geophysics Agency (BMKG) has forecasted the start of the rainy season in the majority of Indonesian regions will likely delay for 10 to 30 days.

    The agency’s latest report noted that out of 342 season zone, 69 of them will enter the rainy season starting October, 161 of them in November, and 79 of them in December.

    Only six areas will experience an earlier rainy season in August and the other 15 areas in September.

    BMKG head Dwikorita Karnawati in a press release explained the rainy season will arrive late in North Sumatra, most areas in Riau, central areas of Jambi, most areas in South Sumatra, some areas in Lampung, most areas in Java, Bali, NTB, NTT, Central Kalimantan, South Kalimantan, some areas in East Kalimantan, some areas in Central Sulawesi, Southeast Sulawesi, South Sulawesi, and North Maluku.

    Meanwhile, in Aceh, North Sumatra, some areas in Riau, Jambi, Central Kalimantan, East Kalimantan, some areas in North Kalimantan, and Jayawijaya mountain areas will enter the rainy season since August until October.

    Particularly in Papua, the rainy season will begin in November, except the southern areas and Merauke in December.

    The delay is attributable to the sea surface temperature in the Indian Ocean, the western part of Sumatra, and Indonesian waters in the south equator that is colder than normal.

    “As a result, the seawater is difficult to evaporate, and the rainy clouds formation decreases, so there will be less rainfall,” said Dwikorita last week.

    Additionally, BMKG predicted that the rainy season will peak in January-February 2020. Therefore, he reminded regions that are vulnerable to flooding and landslides to stay vigilant.
