Residents in the east awake to their coldest start to October in years. The first of October has seen most places across New South Wales and southeastern Queensland fail to reach their October averages. However, it was the beginning of the month and temperatures below the monthly average should be expected. In Brisbane today, the temperature reached 22 degrees which makes it the coldest start to October in at least eight years. At nearby Archerfield airport, temperatures also reached 22 after a chilly night, dropping down to just 11 degrees, the coldest night in three weeks. Elsewhere in Queensland, Warwick only reached 17 degrees in the day, their coldest start to the month in at least 16 years. It was similarly cool across New South Wales. Sydney climbed to just 18 degrees and Penrith to 19. That makes it their coldest start to October in six years. Further afield, Glenn Innes Airport reached just 13 degrees, the coldest start to the month in at least 14 years. Low daytime temperatures on Thursday, followed by clearer skies overnight allowed temperatures to drop. The cloud then quickly built in today, which was the main factor to the low daytime temperatures.
