The Lowdown
Alright folks, Rusty here. Let’s get into it for Marlin. Straight up, I’m looking at a pretty grim stretch ahead. The next couple of weeks are looking like a write-off for any decent surf. We’ve got a 16-day window with no real highlights to speak of, so brace yourselves for a long flat spell.
The first recommendation doesn’t come until the morning of Thursday the 13th of August, and even then, it’s a tough sell. The water temp is sitting about average for this time of year, so no surprises there.
The rest of the first week is a total washout. Winds are mostly cross-onshore or onshore, with a gentle breeze through Friday, but the swell is small, short period (7 seconds), and combined energy is weak, barely cracking 200 (204). The conditions are just messy and choppy. Saturday the 9th and Sunday the 10th are the same sad story. Monday the 11th gives us rain showers and a bit of cross-onshore chop. Nothing to get excited about.
Tuesday the 12th sees the swell bump up a touch to 5ft from the ESE, and combined energy climbs to 424, but the period is still a weak 7 seconds and the wind is onshore or cross-onshore. It’s going to be a bumpy, blown-out mess. Not worth the paddle.
Thursday the 13th and Friday the 14th are the closest we get to anything. The Thursday morning shows a 6ft swell from the SSE with an 8-second period, and combined energy hits 807. The wind is light and onshore from the SE, which is a bit better, but the forecast still calls it marginal. Friday morning has a 4ft swell from the S with a 12-second period, giving it some shape, and combined energy at 481, but again, the wind is cross-onshore. It’s still not clean.
The second week is more of the same. From the 15th to the 23rd, the swell hangs around 2ft to 5ft, with periods between 7 and 12 seconds, and winds are either onshore or cross-onshore. The combined energy stays in the low to mid hundreds, with a few days barely touching 200. The only spot of note is the morning of the 19th, where the swell from the SSE is 4ft and the period is 8 seconds, but the wind is still onshore. Not enough to salvage the week.
Look, I’m not gonna sugarcoat it – this is a dry run. With no clean conditions, consistent onshore winds, and small, choppy swells, it’s a classic case of “leave the board in the car.” The sets are short and weak, and the wind is ruining any chance of a decent wave. Marlin is a consistent spot, but it tends to go through these blank spells when the wind doesn’t play ball. The outlook is dour, but forecasts can change. For now, this is a solid “stay home” window.
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.
