The Lowdown
Alright folks, let's get real here. This stretch is flat and fugly for the next 16 days. No two ways about it. The swell is hanging around from the east-southeast to east, mostly short period (8 seconds or less), and the wind is onshore or cross-onshore nearly every single day. That spells messy, bumpy, poor surf conditions all the way through.
Starting Tuesday 8th September: tiny 2ft, 8-second ESE swell mixing with some S energy at 9 seconds. Combined energy is weak (91 to 113). Onshore wind means it’s a no-go. Water temp feels about average for this time of year.
Wednesday 9th: swell bumps to 4ft but with a shocking 6-second period – pure windswell. Combined energy hits 269. Winds still onshore. Not worth your time.
Thursday 10th: a 12-second S swell at 3ft – longer period is promising, but cross-onshore wind and combined energy of 401 still means it’s choppy and unappealing.
From Friday 11th all the way to Monday 21st September: locked-in pattern of 4ft to 5ft swell, mostly from ESE or E, short period (6-8 seconds), and onshore or cross-onshore wind. Combined energy bounces between 160 and 731. Even the higher energy days (like Wednesday 16th at 704 and Thursday afternoon 17th at 805) are all tagged as “poor surf conditions”. Those longer period swells around 15 seconds on the 15th and 13-14 seconds on the 16th would work better at a point or reef, but the onshore wind wrecks them. No clean waves.
The whole 16-day run is a bust. Even into late September (22nd and 23rd) it’s more of the same. The break is exposed to S swell, which is its best direction, but we just never get the right combo of size, period, and clean wind.
If you’re really hard up, maybe a beginner could mess around on some 2ft to 2ft slop on a dead-calm day, but those days aren’t happening. This stretch looks better for the kite crowd than paddle surfers. These blank runs don’t usually last forever, so keep checking – forecasts can flip.

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.
