Sydney's water storage is currently at 73.5% of capacity. This is similar to December levels, and 23% higher than at the beginning of 2010 (51%). Current water storage information can be found on the new Bureau of Meteorology Water Storage web site.

The average daily maximum temperature in Sydney during January was 27.4 °C, 1.5 °C above the historical record of 25.9 °C.

Minimum temperatures were also well above average during the month, averaging 20.9 °C compared to the historical average of 18.7 °C. This was the second warmest January on record for overnight temperatures, following 21 °C in January 1991. In addition, Sydney Airport and Riverview Observatory recorded their warmest average night time temperatures on record during the month.

Winds were generally northerly to easterly at Sydney Airport during January, with 60% of 3pm winds coming from that direction. The remaining winds were generally S to SE with almost no wind arising from the west, similar to average wind patterns at this station. The strongest winds in the Sydney region occurred on the 24th associated with the passage of a cold front, with 80 km/hr recorded at Port Botany and 74 km/hr at Little Bay.

Sydney Airport recorded an average of 7.6 hours of sunshine per day during this month, which is average for January.

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 Tuesday 1 February 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.
