The Lowdown
Alright, Rusty here. Let’s see what we’ve got in the water. Honestly, this one’s a bit of a heartbreaker. The entire 16-day window is basically a write-off for decent surf. The only real chance to get wet is a short window on Thursday 27th August, and even then, it’s pretty marginal.
The main issue is that persistent onshore to cross-onshore wind from the east and northeast is just chewing everything up right through. The swell is there in size, popping up to 6ft at times, and we even get some long-period energy from the south early on, but the wind is always mucking it up, leaving it choppy and messy.
Forget about Friday 28th right through to the end. The forecast only has "poor surf conditions" written all over it, day after day. That’s a solid two-week stretch of no-go.
Let’s talk about that Thursday afternoon, 27th August. That’s your only real shot.
Marlin will catch a bit of clean energy. You’ll see overhead sets around 4ft coming from the south, but here’s the interesting bit – the period is a solid 16 seconds. That is a proper groundswell, meaning those waves will have real push and shape. But a swell that long can sometimes be a bit straight at a beach break. Still, with the wind turning light and blowing offshore from the east at just 9 mph, it will be glassy and clean. The water is a warm 79°F. This spot is consistent, so it has to break. The energy that afternoon is moderate (768), so it won't be firing, but it’s your one clear, clean chance. Crowds are a possibility here on a Thursday.
The rest of it? There’s a little pulse of southerly groundswell right at the very end of the run, around 10th and 11th September, with big 15-16 second periods again. But those days just carry rain showers or thunderstorms and wind from the east at 12 mph, which isn't clean. It’s a real shame, as there’s energy in that water.
So, to sum it up: chase the clean conditions Thursday afternoon or expect a long, long wait. It’s a tough outlook. Stay patient.
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.
