Woollen socks weather has finally arrived in Sydney, thanks to a burst of autumnal winds that fed along the New South Wales this morning, according to weatherzone.com.au. Sydney peaked at 30 degrees yesterday, five above the March norm. But today saw a maximum almost ten degrees less, surely heralding the end to Hawaiian shirt season. Other chilly locations as compared to yesterday include: - Gosford only hit 19, seven below average and 11 degrees colder than yesterday - Penrith weakly touched 21 degrees, 9 less than yesterday - Kiama reached 20, eight degrees nippier than Tuesday Perhaps there are some thinking that this is just a brief cold snap. These people are wrong. Tomorrow southeasterly winds are expected to keep temperatures down along the NSW coastline, from Merimbula (which will reach just 21) to Newcastle (slightly warmer at 25). Sydney itself will see the mercury peak at 23 degrees each day until Tuesday, with a shower or two expected tomorrow, mainly later in the afternoon. For those who want to enjoy warmer climes for just a little longer should head further north. However, temperatures of thirty degrees are now as rare as snow in the Bahamas.
