May Warmest On Record For Sydney - Breaks 1958 Previous High By .5C - SMH
Sydney's remarkable spell of warm weather has been so prolonged that any reversion to long-term averages will feel almost chilly. The city will cap a record month on Saturday with daily tops averaging about 23.2 degrees, eclipsing the previous warmest May - set in 1958 - by about half a degree, according to Bureau of Meteorology figures.
This autumn was also Sydney's mildest, adding to last year's record warm winter and spring and making the past 12 months the city's hottest in 155 years, Weatherzone says.
While 2013 was the city's hottest calendar year, Sydney had probably not had a run of such exceptionally warm seasons since 1914, said Acacia Pepler, a climatologist for the bureau. Back then "we had the warmest autumn, the second warmest winter, equal warmest spring, and then the second warmest summer", Ms Pepler said.
1914 was also an El Nino year, which this year is also shaping up to be. During El Nino years, southern Australia, including most of NSW, can expect drier and hotter winters and springs, with the potential for droughts and active fire seasons.
