The Lowdown
G’day, Rusty here. Look, I’ll level with you – the next couple of weeks at Marlin are a real mixed bag, and honestly, not a whole lot to get excited about for a while. The first week or so is pretty much a write-off for decent surf, with a lot of onshore wind messing things up. Things do start to look a bit more promising towards the second week, but it’s a long wait.
Right now, from Friday the 28th of August right through until Sunday the 6th of September, it’s pretty grim. The wind is mostly cross-onshore from the east, blowing at 9 to 12 mph, and that’s just making everything choppy and poor. The swell is hanging around the 3 to 6 ft range, but it’s mostly from the east or southeast, and the period is short, between 7 and 9 seconds, so there’s no real power or shape to it. The combined energy is weak to moderate (104 to 455). The water temp is about 79°, which is normal for the time of year. You’d be wasting your time paddling out.
There’s a slight change come Monday the 7th of September. The swell picks up to 7 ft from the SSE, with a period of 8 seconds and the combined energy gets up to 646. But the wind is still cross-onshore from the ENE at 9 mph, so it’s still pretty choppy. It’s a marginal call at best.
The real standout, if you can wait, is looking like Friday the 11th and Saturday the 12th of September. We’ve got a solid groundswell coming in from the SSE with a very long period of 16 seconds. The combined energy jumps right up to 1233, which is strong. The swell is 5 ft on Friday morning and 5 ft on Friday afternoon, dropping to 4 ft on Saturday. The wind is forecast to be onshore from the east and ESE, which isn’t ideal, but it’s clean onshore, not cross-onshore, so it’s not as choppy. This is the kind of energy that’ll really wrap in and produce some good lines, especially for the more experienced crew. For a beginner, 5 ft with that much power might be a bit much, but for anyone who knows what they’re doing, this is the best on offer in the whole outlook. It’s a long way out, so keep an eye on it, but it’s the one to pencil in.
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.
