Premium Content Subscriber only If you’ve been thinking it’s time to pull out the jumpers and woolly socks, then you’re not wrong as temperatures are set to plummet this week. Most of NSW and the ACT are currently experiencing a sharp burst of cold weather, with temperatures in many areas 5 to 7 seven degrees below average. And sadly for those who love the heat those lower temperatures are also set to include the Northern Rivers. A Bureau of Meteorology spokesman said while most of the cold snap will be affecting the southern regions, the Far North Coast can also expect temperatures below average.
