BBMKG attributes Bali's cooler temperatures to Australian cold air

BBMKG Denpasar Regional Office stated that cold air masses from Australia are affecting temperatures in Bali, making nights and mornings feel cooler.

“Australia is currently in its winter season, with relatively high atmospheric pressure causing cold air masses to move from Australia towards Indonesia, passing through Bali and surrounding areas,” said BBMKG Regional Office III forecaster Wayan Gita Giriharta in Denpasar on Saturday.

Australia’s winter season occurs from June to August.

The phenomenon of cooler nighttime and morning temperatures typically occurs during Bali’s peak dry season in June, July, and August.

This is caused by the annual apparent movement of the sun and the active Australian monsoon, he added.

“During this period, the sun is positioned in the Northern Hemisphere, leading to a deficit in solar radiation for southern equatorial regions like Bali and surrounding areas,” he said.

Besides the influence of the “kangaroo country”, Bali’s temperature variations are also affected by clear skies with minimal cloud cover.

Such conditions cause solar radiation heat to be released directly into the atmosphere, resulting in cooler surface-level air, especially at night and early morning.

According to BBMKG Denpasar’s forecast, Bali’s minimum temperatures on May 30-31 averaged 20 degrees Celsius, with a maximum of 32 degrees.

The temperatures were one degree lower compared to the previous week’s forecast for May 23-24, which had a minimum of 21 degrees and maximum of 32-34 degrees.

Meanwhile, the lowest average temperatures at Bali tourist attractions are forecasted to be 19-30 degrees Celsius in Bedugul, Tabanan Regency and Kintamani, Bangli Regency on May 31, 2026.
