Weather Forecast 8 June 2026: List of Cities Facing Heavy Rain and Explanation of the 'Bediding' Phenomenon

The Indonesian Meteorological, Climatological, and Geophysical Agency (BMKG) has released the weather forecast for today, 8 June 202cap. Most major cities in Indonesia are predicted to experience cloudy conditions to light rain. However, residents in several regions are advised to remain vigilant against the potential for heavy rain accompanied by lightning and strong winds.

BMKG forecaster Henokhvita explained that there are convergence areas extending from the waters north of North Maluku to West Papua, as well as from South Kalimantan to East Kalimantan. These conditions are triggering significant rain cloud growth along these paths. Meanwhile, regions such as Jakarta, Bandung, Semarang, Yogyakarta, Surabaya, Denpasar, and Makassar are predicted to remain cloudy throughout the day.

In addition to the daily forecast, BMKG provided an explanation regarding the ‘Bediding’ phenomenon—a notable drop in air temperature from night to morning that has recently gained traction on social media. The Director of Public Meteorology at BMKG, Ida Pramuwardani, emphasised that ‘Bediding’ is not an extreme weather phenomenon. ‘Bediding is a seasonal condition where the air feels colder due to reduced cloud cover,’ Ida explained.

According to the agency, when the sky is clear without clouds at night, terrestrial radiation is released directly into the atmosphere without obstruction. This is further reinforced by the influx of dry air masses from Australia (the Australian Monsoon). These cold temperature characteristics typically begin to be felt in June and peak between July and August. The public is advised to maintain their health amidst the contrasting temperature shifts between hot days and cold nights, and to continue monitoring official weather information from BMKG channels.
