The Lowdown
Alright, let’s get into it. I’m gonna be straight with you – the next couple of weeks are looking pretty grim. We’ve got a blank run on our hands, and it’s a long one.
Starting from Sunday the 2nd of August and running all the way through to Sunday the 16th of August, there’s nothing worth paddling out for. Every single session over that stretch gets marked as poor surf conditions. The wind is mostly onshore or cross-onshore, the swell is weak and short-period, and the wave energy just isn’t there to build anything decent. The combined energy is mostly in the low to mid hundreds, like 204 to 968 – all that movement but no real punch.
On Saturday the 15th of August, the swell does bump up to 8 ft from the SSE, with the wave energy hitting 968 and even 1045, but the wind is a fresh cross-onshore at 18–22 mph, plus there’s rain showers. That’s going to be lumpy, choppy, and honestly, more of a kite-surfing setup than a paddle-surfing one. And with the size getting over 8 ft, that’s expert-only if you even try it. The same goes for Sunday the 16th of August – still big at 8 ft but messy.
The one little glimmer comes on Thursday the 13th of August in the afternoon. We get a brief shift: a 2 ft swell from the S with a long period of 14 seconds, and the combined energy jumps to 404. That’s a groundswell pulse, and it’s got some shape to it, but it’s tiny. For a point break or a reef, that long period could link up, but at 2 ft you’re barely riding anything. The wind is onshore from the ESE at 9 mph, so it won’t be glassy.
Bottom line: there are no good surf options in this 16-day window. This is one of those stretches where the forecast just isn’t cooperating. It’s a blank run, but that’s not unusual for this area – sometimes the ocean just shuts down for a bit. Keep an eye on the charts, because it tends not to stay this poor for long.
The water temp at Marlin is 79°F with a 1° anomaly – that’s pretty average for this time of year, nothing unusual there.

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.
