Hot spring but it's been hotter

Alongside ongoing drought conditions Cowra again experienced a warmer than average spring this year.

Statistics from the Bureau of Meteorology showed that both September and October were two and three degrees warmer than their respective historical averages of 18.9 degrees and 23.1 degrees while November has been a degree warmer than its historical average of 27 degrees.

That could increase to two degrees above the historical average if the town's forecasted highs are met today and on Saturday.

However none of these averages are record breaking with the highest average recorded temperature for each month coming in as 23.4 degrees for September (1944), 28.1 degrees for October (2015) and 34.3 degrees for November (1919).

Monthly rainfall will be well down on historical averages with September recording 12mm (50.6mm av), October 6.1mm (56.4mm av) and November currently recording 16.4mm (53.7mm av).

While it's been dry, it's also been drier.

The lowest recorded totals for each month recorded are 1.5mm for September (1957) and 0mm for both October and November (2002, 1922).

The summer outlook won't be bringing much of a change, with the Bureau forecasting a drier than average summer with a 40 per cent chance of exceeding the median rainfall for December to January.

The Bureau is also forecasting December to February nights overall to be warmer than average almost nation-wide and above average daytime temperatures very likely.

Cowra has been given an 80 per cent chance of exceeding its median temperature of 30 to 33 degrees from December to February.

The main influence on the summer outlook continues to be a strong positive Indian Ocean Dipole and periods of negative Southern Annular Mode which are likely to persist until mid summer and mid-December.

NSW is likely to enter the new year with public water storages at their lowest levels in the last five years. Currently NSW accessible volume sits at 5890 gigalitres, just 27.5 per cent of total capacity.
