Warm summer days for much of the country, with warmer nights very likely
December to February maximum temperatures are likely to be above median for much of WA, the NT, much of Queensland, northern and eastern SA, western NSW, western and central Victoria, and Tasmania (greater than 60pc chance). Below median daytime temperatures are likely for eastern NSW extending into eastern Victoria (chance of exceeding the median is less than 40pc).
There is an increased chance of unusually high maximum temperatures (in the top 20pc of historical records) for December to February over most of WA, the NT, western and central Queensland, most of SA, and western parts of NSW, Victoria and Tasmania (1.5 to 3 times the usual chance). In any given outlook period, the chance of unusually high or low maximum temperatures is around 20pc. This means that a 40pc chance of unusually warm conditions is twice the normal likelihood, while 60pc is three times.
Minimum temperatures for December to February are likely to be warmer than median for most of Australia (chances are greater than 60pc), with most areas very likely (greater than 80pc chance). However, south-eastern WA and south-western SA have roughly equal chances of above or below median overnight temperatures (chance of exceeding the median is close to 50pc).
There is an increased chance of unusually high minimum temperatures (in the top 20pc of historical records) for December to February over most of Australia except south-east WA and north-east NSW (1.5 to more 4 times the usual chance), with the highest likelihood for northern Australia.
Past accuracy for December to February maximum temperatures is moderate to very high for almost all of Australia, with moderate to low accuracy for the southern NT. For minimum temperatures, accuracy is high to very high across the southern half of the country and parts of the far north, with moderate to low accuracy for far northern WA, extending into central parts of the NT and across through central parts of Queensland.
