Average temperatures across Sydney for June 2009

A warmer than normal winter has been forecast however when comparing data from nine weather stations across Sydney for June 2009, it has been found that average daytime maximum and minimum temperatures could best be described as "Mixed" for the month. The figures quoted are from the following weather stations (Weatherzone).

Campbelltown.
Dee Why.
Liverpool.
Parramatta.
Penrith.
Prospect (The closest official station to Blacktown where I live).
Richmond.
Sutherland.
Sydney.

Campbelltown

Average max 17.6C. Average min 5.6C (Long term average max - 17.8C. Long term average min - 4.2C)

Hence daily maximum temperatures were slightly below average but the nights were warmer than normal.

Dee Why

Average max 17.9C. Average min 10.3 (Long term average max - 16.9C. Long term average min - 9.3C)

Daily maximum and minimum temperatures were a full 1C above average.

Liverpool

Average max 17.5C. Average min 7.2C (Long term average max - 17.8C. Long term average min - 6.6C)

Hence daily maximum temperatures were slightly below average but the nights were warmer than normal.

Parramatta

Average max 17.8C. Average min 8.1C (Long term average max - 17.8C. Long term average min - 7.4C)

Average maximum temperatures were right on average but the nights were warmer than normal.

Penrith

Average max 17.7C. Average min 7.6C (Long term average max - 18.4C. Long term average min - 6.3C)

Daily maximum temperatures were below average but the nights were warmer than normal.

Prospect

Average max 17.3C. Average min 7.7C (Long term average max - 17.3C. Long term average min - 7.4C)

Daily maximum temperatures were average but the nights were marginally warmer than normal.

Richmond

Average max 17.8C. Average min 6.3C (Long term average max - 18.2C. Long term average min - 4.5C)

Average maximum temperatures were marginally below average but the nights were warmer than normal.

Sutherland

Average max 17.5C. Average min 7.2C (Long term average max - 17.8C. Long term average min - 6.6C)

Average daily temperatures were slightly below average but the nights were warmer than normal.

Sydney

Average max 17.9C. Average min 10.3C (Long term average max - 16.9C. Long term average min - 9.3C)

The maximum and minimum temperatures were a full 1C warmer than normal for this weather station being Observatory Hill.

At the Prospect Weather Station, the daily maximum temperatures for June 2009 were down from that experienced in 2008 (Av max June 2008 - 18.01C and average min for June 2008 - 9.58C).

Hence winter for Sydney has started out "mixed" with respect to average maximum daily temperatures. Some localities experienced a slightly cooler than normal June with respect to maximum daily temperatures while other localities experienced a warmer than normal June.

Generally the nights across Sydney have been above the average for the start of winter.

Reports from Thursday the 2nd July 2009, indicate that the warm winter heat has broken records through out the top end of Australia from WA, NT and QLD.

Gladstone, with a max. of 30C, had its warmest day in July in 49 years of records. Rockhampton in 63 years of records had its hottest July day with a top of 30C.

Charters Towers had 32C, making its warmest July day in 16 years of records.


Mingela was 8C above average breaking a July record with a 30C day, four higher than the previous record in the site's 11-year history.

In the NT, a July record was broken at Centre Island, in the Gulf Country, where it got to 32 in gusty southerly winds.

In the WA Kimberley at Kuri Bay reached 37C, a July record.

During the next few days, dry southerlies will gradually cool down and bring daytime temperatures closer to average. However, nights will become cooler and drop below the norm.

Sydney weather for 6 July 2009

A cold morning for western Sydney and a cool partly cloudy day ensured thereafter. The day had a cool brisk feel to it and the sun had little energy to provide much warmth.

Overnight temperatures in parts of Western Sydney dropped to below 0 degrees Celsius and the 3 pm temperature for Penrith and Richmond struggled to reach 13 degrees Celsius. The 6/7/2009 so far this winter is one of the colder days for the season and the cold morning made it feel like winter.

Maximum and minimum temperatures for some weather stations around Sydney for 6/7/2009 were:-

Suburb               3 pm Temperature        Minimum temperature          Av max (C)      Av min (C)

Badgereys Creek  16 Celsius                   0 Celsius                           17.4               4.3 
Bankstown          15 Celsius                   2 Celsius                           17.2               5.1

Sydney              16 Celsius                   6 Celsius                           16.2               8 
Terrey Hills         14 Celsius                   3 Celsius                           16.7               6.4

Source (Bom 3 pm weather station readings for 6/7/2009 and Weatherzone average temperature and climatology readings for July (Long term July averages).

The above shows that average minimum and maximum temperatures for the day were generally below average, some more so than others which gave the day a cool brisk feel to it.

Run of warm winter days end for Sydney 7/8/2009

The run of mild sunny and even warm winter days for Sydney has come to an end. Starting on Monday 27 July and finishing on Friday 7 August, maximum daily temperatures have reached between 18 and 24C at Blacktown and indeed across much of the Sydney area (BOM Weather Stations). This has been well above the average for July and August.

Indeed maximum temperatures for Friday 7 August 2009 were well above the average for August reaching between 22C and 25C across Sydney.

The run of mild weather came to an end after 4 pm Friday afternoon following the passage of a cloud band and a cold front. No rain occurred at Auburn where I work. The front brought a cooler gusty South West wind change.

Temperature anomalies for New South Wales for 7 August 2009

I have been reviewing the temperature anomalies for Friday 7 August 2009 and it is noted that across Eastern New South Wales, areas east of the cold change experienced temperature anomalies of between 4C and 6C above the average for August. That includes Sydney. It was a warm day for this time of year.

A stark contrast for areas in southern New South Wales behind the change in which temperature anomalies were between 0C and 2C below the average for August.

The plot generated at the Bureau of Meteorology "Water and the Land" for - Daily Mean Maximum Temperature Anomaly for 7 August 2009 shows the contrast in which one half of the state experienced a colder than normal day while the other half experienced a pleasant warm winters day. It also gives an indication on the nature, strength and impact of the cold front that swept across the state and how it affected the maximum temperatures for the day.

It also shows that Victoria experienced a cold day while it was warmer than normal in Southern Queensland.

Another warm August day for Sydney August 21 2009

August 21 has turned out to be another warm day with maximum peak temperatures being well above the average for the month of August.

Despite the cloud cover at times, maximum temperatures for the city at 3 pm fell between 23 and 27 degrees Celsius across the Sydney metropolitan area. According the the weather stations (BOM daily temperature readings 21/8/09) Terrey Hills was the coolest location on 23C while 25C and 26C was common elsewhere. The highest maximum temperature occurred at Badgereys Creek, Penrith and Richmond where the maximum temperature was close to or in the vicinity of 27C.

Temperatures for August 2009 - Sydney and New South Wales

A summary of maximum and minimum temperatures and temperature anomalies specific to Sydney and New South Wales for August 2009 is provided below. The details below are derived from Weather zone and Bureau of Meteorology data bases for various weather stations and the Bureau of Meteorology "Land and Water" site.

Sydney

Generally the days were significantly warmer than normal although minimum nightime temperatures varied from being above average near the coastal areas to being closer to average further inland and even below average at Penrith and Richmond. A sample of what happened in Sydney is provided below:-

Location         Long term Max         Long term Min      Av max temp (Aug 09)    Av min temp (Aug 09)

Bankstown      18.9C                     6C                     21.2C                            6C  
Campbelltown  19C                       3.9C                   20.9C                            4.2C
Parramatta     19C                        7.1C                   21.7C                           7.9C  
Penrith           19.7C                     6.2C                   21.9C                           5.5C
Prospect        18.6C                     6.8C                   21.3C                            6.7C
Richmond       19.7C                     4.4C                   21.3C                            4.1C    
Sydney          17.8C                     8.9C                   20.9C                           10.4C
Terrey Hills     18.3C                     7.1C                   19.6C                           9.4C          


Maximum temperature anomaly - New South Wales

Maximum average temperatures finished up being well above average for many areas of the state. In particular, the following anomalies are observed:-

- Northern inland and North East inland - 4C - 5C above average.
- Sydney and much of the Northern inland - From 2C to 4C above average.
- North Coast - 3C to 4C above average.
- South West - 2C to 3C above average.
- South West slopes and Southern New South Wales - Average to 1C above average. The unusual warmth did not impact this region when compared to other regions.

Minimum temperature anomaly - New South Wales

The minimum temperature anomaly plot shows that average minimum temperatures were closer to average for the state. The exception being the far North West portion where minimum temperatures were 2C to 3C above the average. Many areas experienced minimum temperatures of 0C to 1C above average although a large area being the Hunter Valley, Northern Tablelands, North West Slopes and the Mid North Coast experienced minimum temperatures that were 0C to 1C below average.

Hence it is concluded that while maximum daytime temperatures were generally well above the average for the month across much of the state, night time minimum temperatures were generally closer to the long term average or even slightly below the average.

The relevant plots stated are provided below from the Bureau of Meteorology "Land and Water" site specific for temperatures.
