Annual Water Temperature Trend

Coffs Harbour, or just Coffs if you're a local, is a massive favorite on the Mid North Coast where the mountains pretty much tumble into the Tasman Sea. If you’re keen for a dip, the water here is absolute gold for a good chunk of the year. In the heat of summer, usually around February, you’re looking at a balmy 25°C to 27°C—pretty much like jumping into a warm bath. When winter rolls around in August, the mercury dips to a fresher 19°C or 21°C. While that might feel a bit bracing for some, it’s still mild enough that you’ll see plenty of the local crew out there in just a spring suit or boardies if the sun’s got enough bite.
