Jakarta. Extraordinarily cold weather across parts of Indonesia and Australia over the last week could be repeated if southerly winds from Antarctica were to return, the Indonesian meteorology agency said on Tuesday.
The temperature dropped four to eight degrees Celsius from the July average over the weekend, according to the Meteorology, Climatology and Geophysics Agency (BMKG).
BMKG head Edvin Aldrian said that the temperature dropped as much as eight degrees in Serang, Banten province.
“As late as Monday morning the temperature in Curug was at 23 degrees Celsius while Jakarta recorded 25 degrees on Monday evening,” he said on Monday.
Edvin said that Indonesia’s colder-than-usual temperatures were commensurate with the record-breaking lows felt across parts of Australia, with chilly southerly winds sending temperatures in Brisbane below freezing. July 11 was the coldest day in the Queensland state capital for 103 years.
Indonesia has seen an unusually late start to its dry season, with meteorology chiefs agreeing that the rainy season had lagged well into July.
“There is a small chance that such cold weather will happen again. It was because on Sunday there was low pressure in the Sunda Strait which caused more clouds at the western part of Indonesia, especially West Java and South Sumatra,” he told the Jakarta Globe on Tuesday.
Edvin said that Greater Jakarta was only now beginning to see the start of the dry season, but added that isolated showers were still a possibility. He said that the rainy season will start again around September.
