Sydney is not only shivering through its coldest December in over 50 years, but it's also facing the humiliation of being colder than both Melbourne and Launceston! So far this December, Sydney's maximum temperature is running at just 22.2 degrees, which is three whole degrees below average. It's likely that the city will finish the month very close to the record low average for maxima of 22.5 degrees, set in 1924, even with some warmer days ahead for Christmas Eve and Christmas Day. While Sydney has been shivering with an almost endless run of cloud cover and cooler southerly winds, those to the south have been blessed with some summer warmth. Adelaide has a forecast top in the mid 30's today, while Melbourne should also crack the 30 mark. Melbourne's average maximum temperature so far this summer is running at 24.5 degrees, 0.3 above the December average and more than two degrees warmer than Sydney. Even parts of Tasmania are seeing warmer weather than Sydney, which is rarely the case. Launceston has an average maximum temperature of 22.5 degrees so far this month, 0.3 above that of Sydney. Not only that but it has had multiple days in the mid twenties, with a high of 28 degrees on the 9th December. Sydney has so far only managed a high of 25.6 degrees back on the 11th of the month. For a city which prides itself on its climate, it certainly has been humiliated by its southern cousins so far this summer. Additionally, while Sydney-siders may be complaining about the cold, those in the Pilbara region of Western Australia have the opposite problem. Roebourne hit 49.4 degrees on Wednesday, the highest December maximum temperature on record for that state.
