The Lowdown
Alright folks, Rusty here. Let's have a look at what Marlin's got cookin' for us over the next couple of weeks.
Honestly, it’s a bit of a grim outlook for Marlin. Right off the bat, we’ve got a long stretch of poor conditions. From the 12th all the way through to the 27th of September, the forecast is pretty bleak. The wind is mostly coming out of the east, blowing cross-onshore or onshore, keeping everything messy and choppy. The swell is hanging around the 2.6 ft to 4.9 ft range, but with the wind state being what it is, it's just not worth paddling out for. The combined wave energy stays in the weak to moderate range (184 to 408) for most of that time, so there’s just no power or shape to work with.
Now, there is a glimmer of hope right at the very end of the period. On Sunday the 27th of September, things start to shift. We’re looking at a clean 2.9 ft swell coming from the south, with a period of 16 seconds. That’s a very long period groundswell, which is a treat. The combined energy jumps up to a strong 545, telling you there's some real juice in the water. The wind is forecast to be light and onshore, but it’s the only window in the whole run that even scores a 1 out of 10, so it’s our best shot. This long-period swell will wrap nicely into Marlin, but it's a beginner-friendly spot, and with that amount of power, be careful. The water temp is a pleasant 79.3° with a water temp anomaly of 0.8°, which is pretty standard for this time of year.
So, after a dead spell of over two weeks, there’s finally something to look forward to on the morning of Sunday, September 27th. Hope it cleans up.

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.
