The Lowdown
Alright, Rusty here. Let’s take a look at what’s cooking for Marlin over the next couple of weeks.
Honestly, it’s a tough stretch. We’ve got a full 16-day window ahead, but the surf is going to be poor-to-rubbish for the whole run. There isn’t a single standout session in the mix, so if you’re keen for a paddle, you’ll be battling onshore slop and chopped-up conditions the whole way. This is one of those periods where the ocean just isn’t playing ball.
The first recommendation doesn’t show up until Sunday, September 6th, and straight away it’s a letdown. Marlin is a consistent beginner-friendly spot, exposed to the south, and it usually needs a clean S swell to work. But for the first week, we’ve got easterly and southerly swells mixing in, mostly around 3ft to 5ft, with short periods of 6 to 8 seconds. That means weak, messy waves. The wind is either onshore or cross-onshore from the east and northeast, blowing 9 to 12 mph, so it’s choppy and blown out. The combined wave energy is weak to moderate, ranging between 100 and 474 — nothing to get excited about.
Mid-week, around the 10th, the swell gets a little boost but the period is still short and the wind stays on it. By Thursday the 10th afternoon, there’s a 5ft ESE swell at 7 seconds (432 combined energy), but it’s onshore and scrappy. That pattern holds right through the weekend. On Sunday the 13th, we see 5ft at 8 seconds from the east, but again, it’s cross-onshore and choppy — just not worth the drive.
Now, things get a bit more interesting in the second week, but still not enough to save the outlook. Around September 15th, a long-period S swell arrives — 2ft at 16 seconds Tuesday morning, and 2ft at 15 seconds in the afternoon. Combined energy jumps to 582 and 326, but the wave height is tiny. Long-period swells like that need a point break or reef to shape up, and with cross-onshore wind from the east at 12 mph, it’ll be bumpy. That’s more of a novelty than a session.
Right through to the 21st, it’s the same story: onshore or cross-onshore winds, short-period ESE swell around 4ft to 5ft, and combined energy in the 250–450 range. The waves will be sloppy, closed-out, and messy. At 5ft to 5ft, it’s getting a bit big for beginners, and with that short period and onshore wind, even experienced surfers won’t find much joy.
Bottom line: there’s no good surf in this 16-day window for Marlin. If you’re a kite surfer, the consistent onshore wind might get you out on the water, but for a paddle surfer, it’s a blank run. Don’t stress — forecasts change, and this stretch can’t last forever.
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.
