Indonesia's meteorological agency, BMKG, forecasts light to moderate rain across various regions on Thursday, February 19, 2026, marking the first day of Ramadan 1447 H. The prediction includes major cities from Sumatra to eastern Indonesia. Authorities advise the public to remain alert for potential extreme weather during the peak rainy season.
Indonesia's Badan Meteorologi, Klimatologi, dan Geofisika (BMKG) predicts that weather across various regions on Thursday, February 19, 2026, will be dominated by light to moderate rain. This date coincides with the start of Ramadan 1447 Hijriah/2026. BMKG forecaster Ina Indah reported that cities on Sumatra, such as Aceh, Medan, Pekanbaru, Padang, Tanjung Pinang, Jambi, Bengkulu, Palembang, and Lampung, are likely to experience light to moderate rain.
"For Java, light to moderate rain will occur in Serang, Jakarta, Bandung, Semarang, Yogyakarta, and Surabaya," Ina Indah said in an online broadcast from Jakarta.
In Bali and Nusa Tenggara, light to moderate rain is forecasted for Denpasar, Mataram, and Kupang. On Kalimantan, similar rain is possible in Tanjung Selor, Samarinda, and Palangkaraya, with thunderstorms in Pontianak and Banjarmasin requiring caution. On Sulawesi, Makassar is expected to be cloudy, while Mamuju, Kendari, Palu, Gorontalo, and Manado may see light to moderate rain.
In the eastern regions, light to moderate rain is generally predicted for Sorong, Manokwari, Ternate, Nabire, Jayapura, Jayawijaya, and Merauke, with Ambon having thick clouds. BMKG Head Dwikorita Karnawati—though sources mention Teuku Faisal Fathani—emphasized that Indonesia remains in the peak rainy season of January-February, which will ease but still hold potential for high intensity.
“The first thing we need to convey is that we are still in the peak of the rainy season in January-February, then it will ease. However, high-intensity rain still occurs in most parts of Indonesia,” said Teuku Faisal Fathani.
BMKG forecasts February 2026 rainfall as low to high, with very high amounts in West Java, Central Java, East Nusa Tenggara, and South Sulawesi. In March 2026, rainfall will be medium to high, very high in West Java, Central Java, South Sulawesi, and Central Papua. During Eid al-Fitr, phenomena such as the Asian Monsoon, Madden-Julian Oscillation, and potential tropical cyclones will remain active, especially south of Indonesia. The public is urged to stay alert for extreme weather.
