Melbourne climate summary for the month of February 2012
Rainfall slightly 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 much warmer than those usually experienced and averaged 16.7°C (departure from normal 2.1°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 also warmer than those usually experienced and averaged 27°C (departure from normal 1.2°C). Total rainfall for the month was 57.6 mm, this being slightly more than that usually recorded (normal 48.0 mm, percentage of normal received 120%).
Some 20 kilometres northwest of the Melbourne city centre, and more representative of the suburbs, is Melbourne Airport. Here, overnight minimum temperatures were near to those usually experienced and averaged 14.4°C (departure from normal 0.3°C). Daytime maximum temperatures were also near to those usually experienced and averaged 26.9°C (departure from normal 0.4°C). Total rainfall for the month was 83.4 mm, this being much more than that usually recorded (normal 44.2 mm, percentage of normal received 189%).

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 am on Thursday 1 March 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
(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.
