The Lowdown
Alright, Rusty here. Let's have a look at what's cooking.
Right, straight up, for the next 16 days starting from the 15th of August, it's a pretty grim picture. We've got a long stretch of poor surf conditions and choppy waters, with no real standouts worth getting excited about. The whole forecast is a bust for paddle surfing.
The best looking day on paper is Saturday the 15th of August, late afternoon at Marlin. We’ve got a 0.9m swell rolling in from the south with a long 13-second period – that’s proper groundswell energy, with moderate energy pushing through (609). The wind is light from the ESE, just 10 km/h, so it's glassy. The water is sitting at 26°, which is about normal for the time of year. But even then, the wave comment says it’s marginal with questionable tide conditions. It's a small, clean wave for beginners on a consistent break, and crowds are possible. It's the only session that even gets a score above zero.
From Sunday the 16th right through to the 30th of August, we’re looking at a run of poor surf. The onshore and cross-onshore winds from the southeast and east are just shredding any chance of a good wave. Swell sizes bounce between 2 ft and 7 ft, but with short periods often around 7-8 seconds, it’s all windslop. The combined energy is moderate at best, but with these winds, it’s just a messy, choppy ocean out there. On days like the 17th and 18th, the swell pushes over 6 ft with fresh winds – that's not good for anyone. It's blown out, messy, and honestly, it looks more interesting for kite surfing than a paddle session.
So, no hidden gems here. It’s a blank run that’s pretty typical for the area when the wind turns nasty. You can hang up the board for a bit; this one's a write-off.
Rusty.

Information about the Marlin Surf forecast
The above surf forecast table for Marlin provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Marlin can be found by selecting the local surf guide option on the grey menu. Our Marlin surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Marlin) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Marlin may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
