Five days after snow fell across Orange last Saturday there is still plenty lying around on Mount Canobolas and at The Pinnacle.

With the mountain access still closed due to the wet and icy conditions snow seekers have been heading to The Pinnacle to enjoy a winter wonderland.

The snow's sustainability has been helped by freezing overnight temperatures this week.

At 5.30am on Thursday it was minus 5.8 degrees.

A Bureau of Meteorology spokeswoman said not only was it Orange's coldest minimum of the year it was our coldest August low since 2006 when it dipped to minus 6.1 degrees.

"The coldest recorded temperature in Orange [from the Orange Regional Airport weather station] was in June 2006, minus 8.3 degrees," she said.

The temperature will hit a sunny 16 degrees over the weekend before Orange gets set for a wet spring.

The Bureau released its spring outlook on Thursday with its Manager of Climate Operations Dr Andrew Watkins saying it will be wet in our region.

"[There is a] greater than 80 per cent chance of exceeding median rainfall for the majority of the state, particularly central and western NSW due to an increased likelihood of a La Nina [weather pattern] forming," he said.

Dr Watkins said La Nina occurred when equatorial trade winds became stronger, changed ocean currents and drew up cooler deep water in the Pacific Ocean.

"A La Nina also typically brings cooler and cloudier days, more tropical cyclones and an earlier onset on the first rains of the northern wet season," he said.

And for those people fearing the forecast might not come true he said spring was the time when there was a higher reliability of weather outlook models.

Dr Watkins said this August had been wetter than the average rainfall for the month for the first time in four years while winter had been warm.
