Annual Water Temperature Trend

Nestled between the Tweed River and the salt-sprayed coastline of the Northern Rivers, Casuarina is a proper hidden gem for anyone looking to get their hair wet in the Coral Sea. Because it sits right in that sweet spot of Northern New South Wales, the water stays fairly inviting for most of the year, usually hovering around a refreshing 19°C in the middle of winter and climbing up to a balmy 26°C or 27°C during the peak of the summer heat. It’s the kind of spot where you can ditch the thick rubber for a good portion of the year, though you might want a spring suit if the southerlies start kicking up in July. The ocean here is generally clean and clear, making it a cracking spot for a dip if you’re keen on avoiding the madness of the more famous breaks further south.
