Indonesia weather outlook July 15‑16 2026: largely sunny, some local rain

The Indonesian Meteorology, Climatology, and Geophysics Agency (BMKG) forecast that most of Indonesia will experience clear to partly cloudy conditions on July 15‑16, 2026. Cities such as Banjarbaru, Gorontalo, Jayapura, Kendari, Kupang, Makassar, Manado, Surabaya, Yogyakarta and many others are expected to be sunny, while Jakarta, Banda Aceh, Bandung, Jambi and other major urban areas will see mostly cloudy skies. Light rain is possible in isolated locations including Bengkulu, Pontianak, Serang, Tanjung Pinang, parts of Sumatra, and the eastern islands.

BMKG also reported that 60.5 % of the archipelago has entered the dry season as of the first ten days of July, an 11.6 % increase from the previous period. The dry spell is linked to lingering El Niño conditions and is accompanied by longer periods without rain, raising concerns about drought, reduced water availability and heightened forest‑fire risk (karhutla). The agency warned residents to stay hydrated, avoid open‑flame activities and be vigilant for strong winds, thunderstorms and localized flooding.

Overall, while the majority of the country can expect favorable weather for outdoor activities, authorities urge continued monitoring of weather updates, especially in regions where rain or fire danger is forecast.
