*** Forecast - Our water temperature forecast

Actual near-shore water temperatures in Lennox Head can vary by several degrees from the values shown, particularly after heavy rain, strong southerlies, or prolonged windy conditions. Certain wind patterns can trigger upwelling, where cooler, deeper water is pushed to the surface and replaces the warmer top layer, leading to noticeable short-term changes in water temperature.

Our water temperature forecast is produced using a proprietary mathematical model that combines real-time measurements with long-term historical patterns, local weather conditions, wind strength and direction, and air temperature specific to each coastal region. To improve accuracy, we cross-check data from nearby locations and use multiple sources, including offshore buoys, satellite-based sea surface maps, and observations provided by local authorities.

Annual Water Temperature Trend

Lennox Head, or just Lennox to the locals, is a legendary coastal town that packs a serious punch when it comes to the salt water. If you’re heading in for a dip, you’ll find the Coral Sea here is a real winner. In the height of summer, usually around February, the water temperature hits a glorious 25°C to 27°C, which is spot on for a long soak. When the winter westerly winds kick in during August, it’ll drop back to a fresher 19°C or 21°C. While that might be a bit brisk for some, it’s still mild enough that you’ll see plenty of people out there with just a bit of rubber or even going skin only if the sun’s out and the coffee’s hot.

Swimming Conditions

Swimming is absolutely allowed and encouraged, but you’ve got to play it smart. Seven Mile Beach is the main stretch, and while it’s world-famous for its right-hand point break, the southern end near the surf club is where you want to be for a swim. It’s patrolled by the local legends at the surf club from September through to Easter, so always make sure you’re between the red and yellow flags. If the ocean swell is looking a bit too beefy for your liking, you can always wander across the road to Lake Ainsworth. It’s a freshwater tea-tree lake that’s as calm as a millpond and perfect for a relaxed float without the worry of rips. Whether you're in the surf or the lake, it’s a cracking spot to cool off and soak up the North Coast vibes.
