A blast of polar air from a cold-front in southern Australia last week managed to push all the way up to the tropics. Darwin shivered through it's coldest August night on record Monday after the temperature dropped to just 13.1C Monday, more than seven degrees below the August average minimum of 20.4C.

Other areas to also record cold minimums overnight in the Darwin-Daly forecast district include Middle Point (5C), Tindal (6.1C), Noonamah (8.6C) Batchelor (10.8C) and Dum Inn Mirrie (12.9C)

This comes after the coldest month of May on record and the coldest June day on record.
