Victoria in June 2012:

Dry, with frosty nights, in the north.

Above average rainfall, and cool days, in the south.

Summary

Bureau of Meteorology data show that across the State of Victoria, overnight minimum temperatures were slightly cooler than those usually experienced. Daytime maximum temperatures at most localities were near to those registered in the past. Total rainfall for the month was generally slightly more than that usually recorded.

Over the northern plains, minimum temperatures were cooler than those usually experienced (average departure from normal -1.1C). Daytime maximum temperatures at most localities were near to those registered in the past (average departure from normal 0.2C). Total rainfall for the month was generally slightly less than that usually recorded (average percentage of normal received 73.5%).

In southern districts, minimum temperatures were near to those usually experienced (average departure from normal 0C). Daytime maximum temperatures at most localities were very slightly below those registered in the past (average departure from normal -0.4C). Total rainfall for the month was generally much more than that usually recorded (average percentage of normal received 162%).

Synoptic and other drivers

During June 2012, there was a persistence of low pressure systems over the Tasman Sea, especially the north Tasman, and a persistence of high pressure systems to the south of the Australian continent.  Between these two features, cool and moist southerly air flow was directed on to the Victorian coast. As a result, there was little moisture left for the northern plains - hence, the drier conditions there.

Climate indicators remain at neutral (neither El Nio nor La Nia) levels, the tropical Pacific continues to slowly warm. Climate models surveyed by the Bureau suggest this warming trend will continue over the coming months, with the majority of the models indicating the tropical Pacific will approach or possibly exceed El Nio thresholds by the end of winter. No climate models favour a return to La Nia during the remainder of 2012.

Large parts of eastern Australia are usually, but not always, drier than normal in winter and spring during El Nio events.

The Indian Ocean Dipole (IOD) is currently neutral. The Bureaus climate model indicates a possibility of a weak positive IOD event developing during winter or spring.

Melbourne climate summary for the month of June 2012

Rainfall more than that usually received.

Located in the Central District at the head of Port Phillip Bay, Melbourne is Victoria's State Capital. Here, overnight minimum temperatures were warmer than those usually experienced and averaged 8C (departure from normal 1.1C). That the overnight temperatures in Melbourne are higher than those in most surrounding localities is a consequence of the city being under the influence of the effect of urbanisation (cities are usually warmer than their rural surroundings, especially at night, because of heat stored in bricks and concrete and trapped between close-packed buildings). Daytime maximum temperatures were near to those usually experienced and averaged 14.4C (departure from normal 0.3C). Total rainfall for the month was 70.2 mm, this being more than that usually recorded (normal 49.2 mm, percentage of normal received 143%).

Notes

A Monthly Climate Summary is prepared to list the main features of the weather in Victoria using the most timely and accurate information available on the date of publication; it will generally not be updated. Later information, including data that has had greater opportunity for quality control, will be presented in the Monthly Weather Review, usually published in the fourth week of the month.

This statement has been prepared based on information available at 10 am on Monday 2 July 2012. Some checks have been made on the data, but it is possible that results will change as new information becomes available.

Averages are long-term means based on observations from all available years of record, which vary widely from site to site. They are not shown for sites with less than 10 years of record, as they cannot then be calculated reliably.
The median is sometimes more representative than the mean of long-term average rain.

The Rank indicates how rainfall this time compares with the climate record for the site, based on the decile ranking (very low rainfall is in decile 1, low in decile 2 or 3, average in decile 4 to 7, high in decile 8 or 9 and very high is in decile 10).
The Fraction of average shows how much rain has fallen this time as a percentage of the long-term mean.
