Rainfall for Sydney 20 and 21 June 2009Substantial fog across large areas of Western Sydney occurred Sunday morning 21/6/09 which cleared mid to late morning only to reveal cloudy conditions. Further light showers occurred during the afternoon around Western Sydney and up until 4 pm 21/6/09 many rain gauges have registered between 0.5 and 2 mm of rain.
Being the day with the shortest amount of daylight hours (Winter Solstice) Sunday turned out to be a cool dull day with the occasional afternoon shower.

Sydney (Observatory Hill) 32 mm, North Manly 34 mm, Allambie 30 mm, Randwick 26 mm and Cromer 25 mm.

Cumulative totals 14 to 21 June 2009The rainfall plot for New South Wales produced at
http://www.bom.gov.au/cgi-bin/silo/rain_maps.cgi in "Water and the Land "Bureau of Meteorology" shows the nature of the rainfall. Much of the rainfall is limited to the New South Wales coastal strip particularly north from Nowra (New South Wales South Coast). Heavier totals have occurred on the coastal strip north from Sydney.
Falls of between 50 and 100 mm have occurred on the coastal strip north from Sydney. An area near Coffs Harbour has received between 150 and 200 mm. A large area of the coastal strip on the North Coast has received between 100 and 150 mm of rain.
Hence for some localities on the New South Wales North Coast, this has been another reasonably wet period.
