The Lowdown
Alright folks, it’s Rusty here. Let’s get straight into it. I’ve looked at what’s comin’ down the line for Marlin, and I gotta be honest with you – this stretch ain’t lookin' pretty. The whole 16-day window is a tough one. We’re talkin’ days and days of onshore, cross-onshore, and cross-shore winds churning up the ocean. The swell is there, but it’s all wind-affected and messy. You’re gonna be staring at a long, blank run with hardly a wave worth paddling for.
From Tuesday, August 25th, right through to Wednesday, September 9th, the story is the same: poor surf conditions. The wind is a constant problem. For the first week, it’s mostly from the east and southeast, blowing right onshore or cross-onshore, chopping everything up. The combined swell energy is generally weak to moderate – values like 175 or 245 (that’s low energy, not enough grunt to clean up). The water temperature is sitting at 79°F, which is about normal for this time of year, nothing to get excited about there.
The swell direction is mostly swinging from the ESE to the S, but the period is short, around 6 to 8 seconds for most of it. That’s junky, wind-driven chop. Even when the swell height bumps up to 5 ft or 6 ft, like on September 6th and 7th, the wind is still on it, making for a close-out shorebreak. On August 27th, we get a slight glimpse of something with a 4 ft, 16-second groundswell from the south, but the wind is still onshore from the ESE, so it’s a no-go. That southern groundswell has some energy (768) but it’s wasted on the conditions.
The wind stays stubborn from the east and northeast the whole time. Even on September 5th, when the swell drops to 3 ft from the south, the wind is cross-onshore, creating a “gentle cross-onshore and fairly choppy” mess. There’s simply no standout day. The closest we get to a “maybe” is Thursday morning, August 27th, when the score is a 1 out of 10 – that’s “marginal surf forecast or questionable tide conditions.” Not a recommendation.
If you’re a kite surfer, this persistent east wind and moderate chop might look interesting, but for paddle surfing, it’s a hard pass. There’s just nothing to ride.
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.
