The Lowdown
Alright, mate, let’s cut to the chase. This 16-day outlook is a real bummer for a surfer. The wind is the enemy the whole time, and the waves just can’t get clean. The water is 79°F, which is pretty normal for this time of year.
Kicking off on Sunday, August 23rd at Marlin, we’ve got a tiny 3ft swell from the east, but the wind is onshore and the energy is weak (107). It’s a washout. Monday and Tuesday are the same story – small, choppy junk. Tuesday morning sees a little bump to 4ft, but it’s still cross-onshore with a period of 7 seconds, just a bumpy mess.
Wednesday, August 26th, the swell period jumps to 14 seconds from the south, giving a combined energy of 331. But the wind is onshore again, so that 2ft of potential is blown to bits. Thursday morning, August 27th, is the closest we get to a “maybe.” The swell is 3ft from the south, with a very long period of 17 seconds, pumping out 696 energy. The wind is cross-onshore, so it’s choppy and only marginal. That long period groundswell will run straight at a beach break like Marlin, not ideal.
From Friday, August 28th, right through to the end of the forecast, it’s a windy, choppy mess. The wind is a constant cross-onshore, sometimes hitting 15 mph, and the swell direction keeps changing. There’s a bit more size on September 5th with 6ft from the south, but the wind is still cross-onshore and the energy is moderate (549). For a beginner spot, that’s too big with poor conditions. The whole setup looks more suited for a kite surfer than someone with a paddle.
No single session stands out here. The wind ruins it all. If you’re really keen, the Thursday morning on the 27th of August is the only time with a hint of promise, but it’s a long shot with the wind.

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.
