Sydneysiders putting up with rainiest start to autumn in decadesBrett Dutschke, Monday April 14, 2014 - 11:36 EST
Sydneysiders are struggling to get the washing dry in the city's rainiest start to autumn in 24 years.
Some rain has been recorded in 29 of the first 45 days of the season. This is 10 more rain days than the long-term average for the first half of autumn, and the highest number to this date since 1990.
One of the contributors has been higher-than-normal humidity due to winds blowing off warmer-than-normal seas much of the time. This is the most humid start to autumn in more than a decade.
Another major factor has been a distinct shift in the weather pattern since summer - an area of high pressure over the New South Wales coast and Tasman Sea has been replaced by low pressure, leading to increased instability.
It has been a sharp turn-around since summer which was the sunniest and least humid in a decade.
Despite being a rainy start to autumn, the city and some northern suburbs haven't been extremely wet. Rainfall has been below the long-term average. The city has gained 146mm, 50mm below average.
For most western and southern suburbs both the number of rain days and the amount of rain have been higher than normal. Penrith has had its highest number of rain days for the first half of autumn in about 20 years and 30 percent more rain than average. Its 24 days of rain have brought 155mm, 40mm more than average.
Looking ahead, there will be a drying trend from Wednesday onwards as showers become lighter and less frequent before ceasing later in the week. Until then getting the washing done will remain a challenge, at least in the city and eastern suburbs where showers will be relatively frequent.
