The Lowdown
Alright, I’ve had a good look at the charts for Marlin. This one’s a bit of a tough run, to be honest, mate. The whole 16-day window is pretty grim for decent waves. We’ve got swell on the cards, sure, but the wind and quality are just not playing ball.
For the first week, from Wednesday the 29th right through to about Sunday the 9th of August, it’s a write-off for proper surfing. The swell is coming from the ESE, but the wind is either onshore or cross-onshore. That means choppy, messy conditions all the way through. Even the modest energy readings (like 306 on Saturday the 1st of August) don’t save it with that wind. It’s going to be a frustrating stretch. The water temp is around 79°, which is about average for this time of year, but that’s about the only decent thing going.
Now, there’s a bit of a change in the second week. On Monday the 10th of August, we see a long-period groundswell coming in from the SSE, a solid 14-second period with a combined energy of 400. That’s a lot of push, but the wind is still cross-on from the ENE, keeping it from being clean. It’s a tease.
The only time things look like they might come together is later on Thursday the 13th of August. We get a very long-period swell from the S, with a period of 16 seconds and a strong energy reading of 405. The wind swings to a light onshore from the SE, which isn’t ideal, but that kind of period is pure quality. For a spot like Marlin, exposed to the south, this is the standout window. It’s going to be a powerful, lined-up groundswell, but it’s still a week and a half away, so you’d want to keep an eye on it. Don’t go booking a trip just yet.
Other than that, it’s a long, flat feeling run with poor surf conditions. For beginners, that 6ft on the 1st of August is going to be too big and messy anyway, so you’re not missing 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.
