Monday, 1 July 2013 - Monthly Climate Summary for Victoria - Product code IDCKGC26R0
Victoria in June 2013:
Dry and frosty finish.
- Overnight temperatures (overall) near to those in most years (but very mild early in the month; lengthy frosty spell later).
- Daytime temperatures slightly warmer than those in most years.
- Rainfall much more than that in most years (almost all of which fell during the first half).
- Melbourne experieced its wettest first fortnight of winter on record.
- By contrast, Melbourne experienced its longest June 'run' of rainless days for more than 30 years (12 in a row between the 19th and the 30th) - there was a 13-day rainless spell in 1982 between the 3rd and the 15th.
- Melbourne experienced its second longest June 'run' of minimum temperatures below 5 deg C (9 in a row between the 19th and 27th)*
- Over southeastern Australia, June was unusual in that on every day between the 12th and the 26th, the prevailing synoptic type was one associated with flow from the east - initially, a rain bearing east coast low followed by a 'frosty' anticyclone (usually, westerly flow predominates during June)**.
*The longest June 'run' of sub-5 deg C temperatures is 12 in a row in June 1972.
**Consistent with the overall strengthening and southward shift of the subtropical ridge that has been observed in recent decades - a feature that has also been predicted by global climate models.

Melbourne climate summary for the month of June 2013:
Rainfall much 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 slightly warmer than those usually experienced and averaged 7.4°C (departure from normal 0.5°C). 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 warmer than those usually experienced and averaged 15.4°C (departure from normal 1.4°C). Total rainfall for the month far was 94.8 mm, this being much more than that usually recorded (normal 49.5 mm, percentage of normal received 192%).Some 20 kilometres northwest of the Melbourne city centre, Melbourne Airport, is more typical of the suburbs. Here, overnight minimum temperatures were near to those usually experienced and averaged 5.8°C (departure from normal -0.4°C). Daytime maximum temperatures were slightly warmer than those usually experienced and averaged 14.1°C (departure from normal 0.5°C). Total rainfall for the month was 128.2 mm, this being much more than that usually recorded (normal 39.9 mm, percentage of normal received 321%).

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 2 pm on Monday 1 July 2013. 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
(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.
The ACORN-SAT dataset is being used for temperature area averages from December 2012 onwards. The major change from earlier datasets is that the ACORN-SAT dataset commences in 1910, rather than 1950, and hence rankings are calculated using a larger set of years.
