Victoria had below average rainfall in parts of northern and western Victoria and well above average rainfall in East Gippsland during May. A low pressure system off the New South Wales coast at the end of the third week of the month caused widespread monthly totals of 200mm to 250mm in Far East Gippsland. The highest rainfall total was 259.8mm at Mallacoota and the lowest, 6.8mm (mean 27.4mm) at Mildura Airport.

A low pressure system off the east coast of Australia led to heavy rainfall in East Gippsland on the first of May.

Another low pressure system developed off the east coast between the 22nd and 26th, once again bringing significant rainfall to East Gippsland.
