The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ for our local stretch.
Honestly, it’s a pretty grim run for the next couple of weeks. The waves are on the cards, but the wind is just killin’ it. We’re looking at a long stretch of poor conditions, so don’t get your hopes up for anything clean. The water is sittin’ at 79°, which is about average for the time of year, so at least you won’t need a thick steamer.
Marlin is the only break on the menu, and it’s a consistent, exposed beginner-friendly spot. The optimum swell direction is from the south, but for the first week and a half, we’re getting hammered by easterly windswell with short, choppy periods of 6 to 9 seconds. The wind is mostly onshore or cross-onshore from the ENE, blowing at 9 to 16 mph. That’s gonna make a mess of it. The combined swell energy is mostly moderate (308 to 543), but it’s all wind-affected junk. There’s a small window on Friday morning, September 4th, where we get a marginal score – a 4ft easterly swell with a 9-second period and light onshore breeze from the ESE. It’s still not great, but it’s the best we’ve got for a while, and it’s the only time the forecast even hints at a chance.
Things get a bit more interesting around Thursday, September 10th. A solid south groundswell arrives, pushing up to 5ft with a very long period of 16 seconds. That’s the real deal, deep ocean energy. The combined energy jumps to 1304 (strong), so there’s plenty of power. But the wind swings back to a cross-onshore E breeze at 12 mph, which will chop it up a bit. For a beach break, a long-period swell like that can break a bit too straight, so it won’t be picture-perfect, but it’s the only real standout in the whole outlook. The next day, Friday the 11th, still has a solid 4ft swell from the south with a 14-second period, but the wind is still messy.
So, if you’re desperate, the morning of Friday, September 4th is your best early bet for a marginal paddle. The real standout, however, is Thursday, September 10th – that’s the one with the most power and potential from that south groundswell, but expect some cross-onshore chop. After that, the run looks poor again. It’s a long wait for not much.
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.
