The Lowdown
G’day, Rusty here. I’ve been staring at the charts for Marlin, and I gotta tell ya, it’s a pretty lean outlook over the next 16 days. There’s hardly a moment where the stars line up.
Right from the jump, the wind is a problem. It’s mostly a cross-onshore or onshore breeze, and the swell just doesn’t have the guts to break through it cleanly. The water’s running about 79°F right now, which is pretty normal for this time of year.
Tuesday the 11th is a total loss. You got 4ft swell from the ESE with a short, choppy 7-second period, and a solid 12 mph cross-on wind. The wave energy is weak (215), and it’s just nasty out there. Wednesday the 12th looks a bit bigger at 6ft from the SSE, but with a lousy 8-second period and more onshore rain showers. Energy bumps up (693), but it’s still blown to bits. Thursday the 13th is more of the same.
Finally, Friday the 14th offers our one and only shot. The morning brings a 4ft swell from the S, and here’s the key – it’s a long-period 13-second groundswell. The wind eases to 6 mph from the NE, so it’s a light cross-on that might just clean it up enough. Energy is moderate (677). For a beginner spot that’s consistent, this is the only time you might snag a few lumpy ones. The long period means you’ll be waiting a bit between sets, but it might have a bit of push. Still, it’s only rated as marginal, so don’t expect much.
After Friday morning, it’s a brutal stretch. Saturday the 15th and Sunday the 16th have 3-4ft swells, but the cross-on wind from the east just messes it all up. The energy is still moderate (514-823), but the description is “poor.” From Monday the 17th all the way to the end of the month, it’s dead. The wind stays onshore from the east, the swell drops to 2-4ft, and the periods get short at 6-9 seconds. Energy levels are weak all the way down to 108. The only tiny glimmer is Wednesday the 26th afternoon, with a 2ft swell from the S and a very long 17-second period, but with a gentle onshore breeze and only 270 energy, you’d be hard-pressed to do anything.
Bottom line: Friday the 14th in the morning is your only real chance, and it’s a weak one. Everything else is a long, quiet gap. For a consistent beginner spot, it’s a rough forecast, but it happens. Keep your eyes peeled for an update.
Rusty out.

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.
