Bali's Temperatures Turn Cooler; BMKG Explains Why

Have you noticed the cooler temperatures in Denpasar? The air has been feeling chilly across several parts of Bali during the night and early morning in recent days.

The Bali Regional Bureau of Meteorology, Climatology, and Geophysics (BMKG) stated that this phenomenon is normal and occurs regularly during the peak of the dry season.

Maria Octorina, a forecaster at BMKG’s Denpasar Region III Office, explained on Friday, 29 May 2026: ‘Air temperatures feel cooler at night during June, July, and August due to the sun’s annual apparent movement and the Australian monsoon’s activity.’

According to Maria, the sun is currently in the Northern Hemisphere, causing southern equatorial regions of Indonesia, including Bali, to experience reduced solar radiation. Additionally, Australia’s winter season is affecting Bali’s air temperature.

‘With relatively high air pressure, cold air masses move from Australia towards Indonesia through Bali and surrounding areas,’ she added.

Maria also noted that clear skies with minimal cloud cover allow solar radiation to escape into the atmosphere, making the air feel cooler, especially before dawn.

‘Thus, surface-level air feels cooler, particularly from evening until morning,’ she concluded.

In the past 24 hours, temperatures in some Bali regions, particularly Jembrana, have recorded around 20 degrees Celsius. However, she confirmed the cooling phenomenon is still normal and recurs annually during the dry season.

‘This occurs annually during these three months, typically felt from 7pm to 8pm WITA and reaching its lowest point between 4am and 6am WITA,’ she added.
