In a pattern similar to that of March, rainfall across NSW in April was distinctly contrasted east and west of the Divide. Below to very much below average rainfall was recorded east of the Divide (in particular, coastal NSW), whilst average to above average rainfall was recorded west of the Divide. However, despite western areas of the state recoding above average rainfall, the overall statewide statewide average rainfall was below average. The statewide average total was 31.5 mm, which is below the historical average1of 46.7 mm. The Murray Darling Basin also recorded below average rainfall, with a basin-wide average of 30.1 mm, below the historical average of 38.1 mm. Below average rainfall has now been recorded in eight of the last ten Aprils for both NSW and the MDB.
Slow-moving high pressure systems in the Tasman Sea were a dominant synoptic feature during April, and contributed to the dry conditions along coastal NSW. Persistant northerly flow across the state, generated by these systems, suppressed the moist onshore flow that usually brings rain to coastal areas. A series of low pressure troughs contributed to the rainfall west of the Dividewest, with moist onshore flow bringing some rainfall to the far northern coastal areas.
Some sites had their lowest total April rainfall on record.Widespread heat was experienced across Australia during April, and NSW was no exception. Both day-time and night-time temperatures were above average throughout the state, particularly early and mid month. With above average maximum and minimum temperatures, the statewide average mean temperature for April was 15.5°C which is 0.9°C above the historical average of 14.6°C. This is the 13th warmest April on record for statewide average mean temperatures.
Under the influence of dominant high-pressure systems, bringing clear skies and warm, northerly winds; the statewide average maximum temperature was 25.0°C which is 0.9°C above the historical average of 24.1°C. This is the 18th warmest April on record for statewide average maximum temperatures.
A build up of heat across the state was reinforced by a lack of cool changes, blocked by persistant high-pressure systems in the Tasman. This, in combination with high humidity, resulted in above to very much above average night-time temperatures. The statewide average minimum temperature for April was 11.9°C which is 0.8°C above the historical average of 11.1°C. This is the 14th warmest April on record for statewide average minimum temperatures.
The above average temperatures experienced during April are consistent with the long-term warming trend in Australia and globally.
Some sites had their highest April mean daily maximum temperature on record.

A Monthly Climate Summary is prepared to list the main features of the weather in New South Wales 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 9 am on Monday 3 May 2010. Some checks have been made on the data, but it is possible that results will change as new information becomes available.
A note about deciles: Deciles are used to give an element (in this case rainfall or temperature) a ranking. Deciles are calculated by arranging the totals in ascending order (from lowest to highest) then splitting them into 10 equal groups (thus the groups are called deciles). The first group would be in decile range one, the second group in decile range two, etc up to the highest annual totals (highest 10 per cent) being in decile range 10.
1Averages: Averages are based on the period 1961 to 1990 which is a convention of the World Meteorological Organisation
Normals are long-term averages 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 for temperature and less than 30 years of record for rainfall, as they cannot then be calculated reliably.
