This was the 7th warmest March on record and the warmest since 27.1 °C was recorded in 2006, as well as the warmest March at Sydney Airport since 1983. The warm days were associated with generally dry, sunny conditions and a lack of southerly winds during the month.

Temperatures reached 33.5 °C on the 28th, the latest day this warm since 33.9 °C on 5 April 1986, with temperatures reaching 34.9 °C at the airport. No days dropped below 20 °C during the month, with 27 consecutive days above 23 °C between the 2nd and 28th, the equal third longest autumn mild spell on record.

The mean minimum temperature at Sydney Observatory Hill was 18.9 °C, 1.3 °C above the historical average. Fourteen nights reached at least 20 °C, well above the historical average of 4 warm nights and the most since 14 warm nights in 2007. The mean temperature at Sydney Observatory Hill was consequently 22.6 °C, 1.5 °C above the historical average and the equal 6th warmest on record.

Other phenomena

The prevailing wind direction at Sydney Airport was northeasterly, with 52% of 3pm winds between ENE and NNE, above the March average of 33%, while just 35% were between SE and SSW (average 40%).

Most values are the precipitation in the 24 hours to 9 am on the day indicated. Days marked with »» are part of a longer accumulation, which is marked like this on the final day. Values over 100 mm have been rounded to the nearest whole millimetre. Days marked with - have a rainfall report of zero; days left blank have no rainfall report (which often indicates no rain fell).
This table is very wide; you may have to scroll sideways to see all the days, and you may need to set the paper to 'landscape' to print.


Notes

A Monthly Climate Summary is prepared to list the main features of the weather in Sydney - Greater Sydney 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 8 am on Tuesday 2 April 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 20 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.
