The Lowdown
Alright, Rusty here. Let’s be straight with you – the next couple of weeks at Marlin are looking pretty grim. The finder shows zero surf recommendations for the entire 16-day window, and every single one of those forecast entries is flagged as “poor surf conditions.” That’s a tough stretch, but it happens here sometimes. The good news is that Marlin is a consistent break, so when the stars align, it can fire. This blank run is just a rough patch, and forecasts can change, so don’t write it off completely.
Right now, the first recorded surf is on Wednesday, September 9th, but it’s not worth paddling out for. We’ve got a weak 3 ft swell from the ESE, with a short period of 8 seconds, and the wind is onshore from the E at 9 mph. The combined energy is 302 (moderate), but the conditions are already messy. That sets the tone for the whole period.
The water temperature is sitting at 79°F, which is about 1°F warmer than normal for this time of year – nothing unusual, just a touch on the warm side.
Through Thursday and Friday there’s barely any improvement. The swell stays around 3 ft to 5 ft, but the wind is cross-onshore from the E or ENE, 9 to 12 mph, keeping the surface choppy and ugly. The period is mostly short, around 7 to 8 seconds, so the waves are weak and won’t hold shape.
Saturday and Sunday, September 12th and 13th, are the same story – 4 ft to 5 ft of messy ESE swell, with cross-onshore winds and moderate energy readings (418 to 281). Not a single window is clean. The wind never goes offshore or glassy, which is the main killer here.
The second week doesn’t get any better. From Monday, September 14th through to Tuesday, September 22nd, it’s a constant loop of 3 ft to 5 ft ESE swell, with onshore or cross-onshore winds from the E, ESE, or ENE. The period is mostly short, except for a couple of days where it stretches to 10–14 seconds, but the wind is still cross-onshore, so it’s a waste. The combined energy bumps up to 488 on Wednesday, September 16th, and even hits 847 on Wednesday, September 23rd, but the cross-onshore wind at 12 mph kills it.
The biggest swell we see in the whole period is 6 ft on Wednesday, September 23rd, with a period of 12 seconds and energy at 847 (strong). That’s the only real pulse of the entire forecast, but the wind is still cross-onshore from the ENE at 12 mph. For a beach break like Marlin, that’s just going to be a lumpy, blown-out mess. Hard pass.
If you’re a kite surfer, the consistent cross-onshore wind and moderate swell could be interesting, but for paddle surfing, there’s nothing here to get excited about. The best advice I can give you is to keep an eye on the charts – a little shift in the wind could turn this around, but right now, the beaches are quiet.
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.
