The Lowdown
Alright, Rusty here. Let’s be straight with you – the outlook for Marlin over the next 16 days is a tough one. We’ve got a real gap at the start. From Saturday the 18th of July right through until the end of the month, it’s just not happening. The wind is onshore or cross-onshore almost every day, and the forecast keeps saying "poor surf conditions." You’ll see a bit of swell around, but it’s a short period, around 8 seconds, and the wind is just ruining it. The combined wave energy fluctuates, but even when it hits 835 (moderate energy) on the Sunday afternoon, the wind is howling from the ESE at 16 mph, so it’s all chop and no shape. That’s a solid week and a half of bad news.
The first real flicker of hope comes on Thursday the 30th of July, but even then, the swell is tiny and the wind is cross-shore. It’s not until the very end of the run, into the first week of August, that something starts to look a little more interesting.
Now, if you’re an experienced surfer, keep your eyes on the weekend of the 1st and 2nd of August. That’s the only time we get a pulse of proper size. On Saturday the 1st of August, we’ve got swell building to 6 ft to 6 ft from the SE, with a short period of 6 to 7 seconds. The combined energy climbs to 399 (moderate), which is a step up. But the wind is still a problem – a moderate cross-onshore from the SSE at 12 mph. It’s going to be choppy and messy.
The standout window, if you can call it that, is Sunday the 2nd of August. The morning shows 7 ft of SE swell, period still short at 7 seconds, but the wind swings to SE at 12 mph and is "on," meaning it’s directly onshore. That’s going to be a bumpy, blown-out mess. The afternoon drops to 4 ft but the period lengthens to 9 seconds, and the wind eases to 9 mph. The combined energy is still 441 (moderate). It’s the best of a bad bunch, but it’s far from clean.
The water temperature is sitting at 79°, which is about average for the time of year with a very small anomaly of +0.7°.
Honestly, there’s no standout perfect day here. The setup looks more interesting for kite surfing than paddle surfing, given the strong onshore winds and choppy conditions. The only positive is that Marlin is a consistent beginner spot, so it tends not to stay poor forever, but this run is a long one. We’ll have to wait and see if the forecasts change.
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.
