Rain Expected to Drench Multiple Indonesian Cities on First Day of Ramadan Fasting
Rain is forecast to drench numerous regions across Indonesia on Thursday, 19 February 2026, coinciding with the first day of Ramadan 1447 Hijri/2026. According to the weather forecast from the Meteorology, Climatology, and Geophysics Agency (BMKG), conditions across much of the country on Thursday will be dominated by light to moderate rainfall.
BMKG forecaster Ina Indah reported that cities across Sumatra — including Aceh, Medan, Pekanbaru, Padang, Tanjung Pinang, Jambi, Bengkulu, Palembang, and Lampung — have the potential for light to moderate rain.
“For Java, light to moderate rain is expected in Serang, Jakarta, Bandung, Semarang, Yogyakarta, and Surabaya,” the BMKG forecaster said during an online briefing followed from Jakarta on Thursday.
In Bali and Nusa Tenggara, weather conditions are forecast to bring light to moderate rain to Denpasar, Mataram, and Kupang. Meanwhile, in Kalimantan, light to moderate rain is likely in Tanjung Selor, Samarinda, and Palangkaraya. Rain accompanied by thunderstorms should also be watched for in the Pontianak and Banjarmasin areas.
For Sulawesi, cloudy conditions are expected in Makassar, whilst light to moderate rain is likely to drench Mamuju, Kendari, Palu, Gorontalo, and Manado.
Finally, in eastern Indonesia, Ina noted that weather conditions are generally forecast to bring light to moderate rain to Sorong, Manokwari, Ternate, Nabire, Jayapura, Jayawijaya, and Merauke. Ambon, meanwhile, is expected to have heavy cloud cover.
Peak Wet Season Period
BMKG head Teuku Faisal Fathani stressed that Indonesia is currently still in its peak wet season period. The agency reminded the public to remain vigilant against extreme weather events that could occur at any time.
“The first thing we need to convey is that we are still at the peak of the wet season in January–February, after which it will taper off. However, high-intensity rainfall is still occurring across most of Indonesia,” he said.
BMKG predicts that rainfall in February 2026 will generally fall within the low to high category. Very high rainfall is likely in West Java, Central Java, East Nusa Tenggara, and South Sulawesi.
Meanwhile, in March 2026, rainfall is expected to be in the medium to high category, with the potential for very high rainfall in West Java, Central Java, South Sulawesi, and Central Papua.
