Rainfall
Sydney Observatory Hill recorded 282.0 mm of rain during July, well above the historical average of 97.4 mm. This was the wettest July since 336.1 mm was recorded in July 1950, and the 7th wettest on record for the city. Rain was very heavy in the eastern suburbs, with totals reaching 319.5 mm at Castle Cove and 312.8 mm at Cronulla, including record-breaking totals at several stations. In comparison, western Sydney received average to below average rainfall during July, with just 26 mm at Penrith and 27.0 mm at Springwood, half the July average.
The high July rainfall was due solely to an East Coast Low event, which brought heavy rain to coastal Sydney between the 20th and 23rd but little rain in western regions. Daily falls reached 130 mm at Terry Hills and 129 mm at Castle Cove on the 22nd, including the wettest day in 65 years of record at Cronulla, while Observatory Hill recorded a 4-day total of 261.8 mm, the wettest four days since an ECL in August 1998 and the wettest for July since 1931.
Some sites had their highest total July rainfall on record.Temperature
Sydney Observatory Hill recorded an average maximum temperature of 17.4 °C during July, 1.1 °C above the historical average. Temperatures were particularly warm at the end of the month, with four consecutive days above 20 °C between the 28th and 31st. In comparison, most other stations recorded below average temperatures, reaching -1.0 °C below average at Prospect Reservoir.
Minimum temperatures were above average across Sydney, 0.6 °C above the historical average of 8.0 °C at Observatory Hill and as high as 1.5 °C above average at Sydney Airport. The warm minimums were associated with a series of warm nights at the start of the month, with nine nights above 10 °C recorded during July compared to the historical average of 6 nights. However, temperatures reached a low of just 5.5 °C at Observatory Hill on the 8th, and -3.1 °C at Richmond on the 9th, associated with cold southerly winds and reports of snow in the Blue Mountains.
Wind
Sydney Airport was dominated by westerly to northwesterly winds during July, forming 67% of 9am winds and 50% of 3pm winds, with a further 40% of 3pm winds from a southerly to southwesterly direction. Eight strong wind days were reported at the Airport, well above the historical average of four days and the highest July frequency since 1999.
The strongest winds in the Metropolitan region were recorded during the ECL on the 20th, reaching 100 km/hr at Port Botany, associated with minor damage in the eastern suburbs. Very strong winds were also recorded in the Blue Mountains, reaching 139 km/hr at Mt Boyce on the 5th, its strongest gust since records began in 2003, as well as gusts above 90 km/hr on the 6th, 7th, 10th, and 11th. The strong winds during this period caused substantial damage in the Blue Mountains, particularly on the 7th and 8th, with numerous fallen trees causing damage to houses and trains and large areas without power.
Other phenomena
Sunshine averaged 6.6 hours at the Airport, equal to the historical average.. There were no thunderstorms at Sydney Airport during July and only one fog day, average for July.

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 10 am on Monday 1 August 2011. 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.
