The Lowdown
Alright, Rusty here. Let’s break it down.
First off, it’s grim for a long stretch. From Saturday the 25th of July all the way through Sunday the 2nd of August, Marlin is a no-go. The wind is onshore or cross-onshore the whole time. The swell is small, mushy, and short-period – mostly from the ESE at 7-8 seconds or less. Combined wave energy is weak to low-moderate, topping out around 239. Water temp is 79°, just average for this time of year.
That’s over a week of nothing worth paddling for. On Monday the 3rd of August, things turn marginal – 4ft to 5ft of ESE swell at 8 seconds, with light onshore wind. The energy bumps up a bit, but the quality is still poor.
Tuesday and Wednesday the 4th and 5th get bigger – up to 6ft to 7ft – but the wind cranks onshore from the SE at 19 to 31 mph, making it choppy and messy. Not worth it.
Then comes the one real standout. Saturday the 8th of August – Marlin sees a solid 10ft of ESE groundswell with a 11-second period. The energy is huge at 1981 (very strong). The wind is light offshore from the ESE, which should make for clean waves. That’s some serious size though – way too big for beginners, only for the experienced crew. And the swell is coming from the ESE, while the break prefers S, so it won’t be perfectly lined up. Still, it’s the best looking day by a long shot.
Sunday the 9th drops back to 8ft with onshore wind and marginal conditions.
So yeah, you’re waiting a long time. The only day that really stands out is Saturday the 8th of August – big, clean, and powerful. Just make sure you’ve got the skills for it.
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.
