After having their warmest October in five years, November has kicked off with a hot day in Sydney.
Hot, dry northerly winds are pushing across the state ahead of a cold front approaching from the west. These winds are transporting hot air from the nation's interior to the east coast.
This allowed temperatures to soar in Sydney during the morning, reaching 27 degrees by 10am and hitting 33 degrees by midday, which is nine above average. After a slow start due to cloud, parts of western Sydney reached 32 degrees by early afternoon. Elsewhere, the airport reached 34 degrees and Gosford hit 35.
Cloud has reduced the heating but sunshine later in the afternoon should allow the temperature to jump with help from gusty westerly winds. It could still heat up to the mid thirties.
A total fire ban is in place for the Greater Sydney and Greater Hunter region due to the hot, dry gusty winds.
A cooler southwesterly change is expected late in the afternoon, cooling the city to the low 20s by early evening. The change also brings the chance of a brief shower and thunderstorm.
This refreshing change will herald a cool end to the week, with daytime temperatures in the low to mid twenties expected to continue into the weekend.
