PALEMBANG, JOURNALARTA.COM – Palembang weather for the next three days is forecast to stay mostly partly cloudy with extreme UV levels during the day, while BMKG includes South Sumatra in a zone with potential moderate-intensity rain for the June 23-25, 2026 period. Residents should prepare for two scenarios: strong sun in the morning and afternoon, then local rain with lightning in the late afternoon and evening.
The impact will be felt right away. The Palindra Toll Road and the East Cross Sumatra Road could see puddles, while flood-prone points such as Ilir Barat, Seberang Ulu, and Jakabaring need closer monitoring. Farmers in Musi Banyuasin who rely on the rainy season are also advised to watch for overflow in low-lying fields.

BMKG Early Warning for South Sumatra
BMKG has designated South Sumatra as an area to watch for increased moderate-intensity rainfall during this period. South Sumatra has not been placed in the Alert category like North Sumatra, Bangka Belitung, or West Java, but that does not mean residents can let their guard down.
Rain is forecast to fall in the late afternoon and evening, lasting one to three hours. Lightning and thunder may accompany localized heavy rain. After the rain, roads become slippery and accident-prone, especially for motorcyclists. Puddles at recurring trouble spots such as Jakabaring and Seberang Ulu can appear within 30-60 minutes after heavy rain.
BMKG updates its early warnings every six hours. If South Sumatra’s status changes to Alert or a higher warning level, an update will be issued immediately. Monitor the InfoBMKG app or the official bmkg.go.id website for real-time data.
Activity Guide for Palembang Residents
In the morning and afternoon, sunscreen SPF 30 or higher is not optional; it is essential. UV Index levels from 8 to 11 can burn skin even when the sky looks partly cloudy. Add a hat and sunglasses, and make sure to drink enough water because 32-33°C temperatures speed up dehydration.
The afternoon changes the equation. Bring an umbrella or raincoat every time you go out after 3:00 p.m. WIB. Avoid standing under tall trees during thunderstorms. For drivers, reduce speed on roads that have just been hit by rain. Unplug electronic equipment from power outlets if thunder is heard nearby.
For tourism activities, the Ampera Bridge and Benteng Kuto Besak remain open as usual. But plan visits for the morning and keep a backup plan if rain arrives earlier than expected.
As for transportation, leaving for work or school 10-15 minutes earlier should help with the traffic that often comes with puddles on the Palindra Toll Road. The alternative route via Jalan Kol. H. Burlian can also be an option if the toll road is disrupted.
