April 2010 Fifth-Warmest For Sydney On Record - SMH

Sydney has experienced its fifth warmest April on record with a month of balmy nights and little rain.

But don't put away the warm clothes just yet with predictions that winter is on the way; it's just running a little late. The average April minimum temperature was 1 degree above the average of 16 degrees. Combined with high humidity and little wind, temperatures rose.

Meteorologist for Fairfax company weatherzone.com.au, Samuel Terry, said a number of high pressure systems meant pleasant weather, but, in bad news for our water catchments, very little rain. "A high pressure ridge extended in over New South Wales for most of the month, preventing any real cold fronts from pushing through. Towards the middle of the month, a humid, northerly wind flow established which really bumped up temperatures," he said.

Mr Terry said Sydney had received well below its normal rainfall for 2010, which is unusual considering most of Sydney's rain usually comes before July. He said unless Sydney receives some "good rain" in May "we could be in a bit of trouble. As well as being a warm month, April was a dry month, with the city collecting only 30 millimetres; just under a quarter of what is normal," he said.
