Sydneysiders awoke to the coldest morning in over a year, making for a chilly commute into work.
Sydney dropped to 5.8 degrees before sunrise, making it the coldest morning since July 15th last year when the temperature fell to 5.6 degrees. For the last fortnight Sydney has enjoyed a run of above average overnight temperatures, however last night's temperature was three below average, bringing the run to an abrupt end.
In the western suburbs, it was generally two to three degrees below average. Richmond and Camden were the coldest in the Sydney Basin with a low of minus one, which is four and five degrees below average respectively.
The chilly morning was caused by a high pressure system that brought clear skies and light winds to Sydney. These conditions combined with a cold airmass, allowing for the cold start to the day and made it a bit tougher to climb out of bed this morning.
The next few mornings won't be as cold with cloud increasing later this evening, helping to trap some of the day's warmth. Winds will also increase with a deepening low pressure system off the east coast.
