The Lowdown
Alright, let’s get into it. This is a strange one for Marlin. The whole 16-day window looks like a write-off for decent surf. We’ve got a solid run of poor conditions for the first two weeks, and honestly, it’s not until the very end of the month that we see a tiny glimmer of hope.
The first ten days are a right-off. From Thursday the 16th right through to the 28th, it’s a continuous slog of messy, cross-onshore winds and poorly shaped, short-period swell. The winds are stuck in the SE to ESE quarter, blowing straight on or cross-on, chopping everything up. We see swell heights ranging from 3 ft to 8 ft, but the period is mostly between 7 and 9 seconds – that’s just windswell, no power, no shape. The combined energy values are moderate, but with the wind and short period, the quality is terrible. The forecast scores are a flat zero the entire time. It’s just not worth paddling out.
Then, on Thursday the 30th of July, we finally get a break in the pattern. The morning shows a glassy, calm wind – a major positive. The swell is small at 4 ft from the SE, with a period of 9 seconds. The combined energy is a weak 240, but the key is the wind: it’s flat calm. This is the only window in the entire 16 days described as “glassy” with “expect good surf conditions.” The direction is SE, which is onshore for Marlin, but with the wind completely dead, it’s going to be clean. The water temperature is about 80°F, which is average for the time of year.
This is a one-morning stand-out, and it’s a long way off – over a week away. The break is a consistent, exposed beginner-friendly spot, but it can get crowded. Because the swell is small and the window is so narrow, the crowds might be less of an issue. For the rest of the afternoon on the 30th and into the 31st, the wind picks back up and the conditions go back to poor.
So, here’s the word: if you’re desperate for a paddle, the only real shot is the morning of Thursday the 30th of July at Marlin. It’s small, but it’ll be clean. That’s it. The rest of the 16 days is a total write-off.

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.
