The Lowdown
Alright, I’m gonna level with you, mate. It’s a tough stretch ahead for Marlin. The finder turned up zero recommendations for the whole 16-day run, so we’re looking at a long gap of poor to marginal surf with nothing worth paddling out for. The wind is mostly onshore or cross-onshore, the swell is short-period and choppy, and the wave comment keeps saying “poor surf conditions” right through. There’s a brief flicker on the 20th of September (Sunday afternoon) where it nudges into “marginal,” but even that’s a stretch. The water temperature is sitting at 79°, which is about 1° warmer than the long-term average – nothing wild, just a touch on the warm side for the time of year.
From now through the first few days, the swell is coming from the ESE with heights around 4 ft to 5 ft, but the period is only 7 to 8 seconds – that’s short-period windswill. The combined wave energy sits between 158 and 256, so it’s weak to moderate, but with a cross-onshore breeze from the ENE or E at 9 to 12 mph, it’s all choppy and messy. Not worth it.
Around the 17th of September (Thursday) we see a bump in period to 10–11 seconds and the combined energy jumps to 488, which is moderate and getting interesting, but the wind swings onshore from the SE and the wave quality stays poor. On the 20th (Sunday), a long-period S swell rolls in at 13 seconds and combined energy hits 565 – that’s moderate, with some push – but the swell drops to just 2 ft to 3 ft, and while the wind is light onshore from the E at 9 mph, it’s still not clean enough to make it good. The “marginal” rating on Sunday afternoon is the closest we get to a wave, but I wouldn’t get excited.
From the 23rd of September (Wednesday) through to the end, the swell stays in the 4 ft to 5 ft range, period jumps up to 12 seconds on the 23rd morning (combined energy 569), but again, onshore and cross-onshore winds kill the quality. The wind never turns offshore in the forecast, and the swell direction from the ESE doesn’t match the optimum S direction for Marlin either. It’s a consistent spot but the conditions are just against us this time. Honestly, if you’re looking for something to do, that onshore slop might be more fun for a kite session than a paddle – the beach setup with strong wind and short-period chop isn’t doing any favours.
Stick with it though – forecasts can change, and it won’t stay this poor forever.

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.
