The Lowdown
Alright, Rusty here again. Let’s break down Marlin in feet and miles.
Honestly, this is a rough one. I’ve gone over the whole 16-day run, and there’s not a single window I’d call rideable. Marlin is a consistent, beginner-friendly break that likes south swell, but we’re stuck with east and southeast swell the whole time. The combined wave energy is weak to moderate (238 to 399), and the wind just won’t cooperate.
We start on Monday, August 31st, with a 4ft swell from the ESE at 8 seconds, a 12 mph cross-onshore wind, and it’s already choppy. Tuesday the 1st is similar: 5ft swell, same wind. Wednesday the 2nd morning shows a 6ft east swell with a 12 mph cross-shore wind and the energy hits 869—sounds okay, but the wind kills it. They call it “marginal.” I call it a waste. The rest of the week and the next week are the same story: cross-onshore or onshore wind, short-period swell (mostly 6 to 9 seconds), and wave heights between 2ft and 5ft. Every single entry says “poor surf conditions” with a score of zero.
Water temp on the first day is 79°, which is about normal for the season.
Even the longer-period swells, like Saturday the 5th afternoon (4ft, 12 seconds from the south) and Sunday the 6th morning (2ft, 11 seconds from the south), are ruined by 12 mph cross-shore or cross-onshore wind.
There is nothing to recommend. It’s a full two-week stretch of onshore junk. For a spot that’s usually consistent, this is a bummer of a run. Sometimes it’s just like that. The forecasts can shift, but for now, don’t bother paddling out.
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.
