The Lowdown
G’day, Rusty here. We’ve got a solid 16-day run for Marley, but it’s got a particular shape to it. The first real action isn’t until Friday the 28th, so we’re kicking off with that.
Friday morning, August 28th, is our standout for the whole window. Marley’s looking prime with a clean 5ft SSE swell, period a touch under 11 seconds, giving the waves some decent push and shape. The wind is light cross-off from the WSW at 3 mph, so the surface will be glassy and good. Combined swell energy is moderate at 655 – there’s enough power in the water to get you into something with a wall. The water temp is 64°, which is pretty normal for this time of year, nothing weird about it. This is the best session on offer – get out there early if you can. Be warned, crowds are possible at Marley.
Friday afternoon sees the wind swing around to the SSE, gusting to 16 mph, making it a lumpy, choppy mess. That session’s a write-off. Same for most of Saturday the 29th – cross-on winds and a short-period S swell that just won’t line up.
Sunday the 30th is small and weak, Monday the 31st morning offers a clean little 2ft S swell with a very long 15-second period, but it’s tiny, and that long period will make it close out straight at the point. Not worth the paddle. Tuesday and Wednesday mornings have some clean, small waves but nothing to write home about – knee-high at best.
Then we hit a dead patch. Thursday the 3rd and Friday the 4th of September are flat and not worth a look. The weekend of the 5th and 6th sees a return of clean, small S swell, but still nothing exciting.
Now, the next real standout is a big one, but it’s a week and a half away. Monday morning, September 7th, shows a massive 10ft S swell, but with cross-shore winds, it’s a messy, powerful beast – not for the faint-hearted, and honestly, the quality is questionable. The real gem for the experienced crew is the following morning. Tuesday, September 8th, morning session: clean 8ft S swell with a 12-second period, light cross-off wind from the NNE. That’s a lot of energy (1956) with a clean face. It’s big and solid – expert territory. The water’s still clean, and the swell direction matches what this break wants. That’s your second big call to mark on the calendar.
After that, the middle of the second week drops off fast – small, windy, and messy through the 9th, 10th, and 11th. There’s a brief, clean window on the morning of the 12th, but it’s small.
So, best bets: Friday morning, August 28th for a fun, clean session in the chest-high range. And Tuesday morning, September 8th, for big, clean, expert-level waves at Marley. Get the wax ready.
Rusty.

Information about the Marley Surf forecast
The above surf forecast table for Marley provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Marley can be found by selecting the local surf guide option on the grey menu. Our Marley 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 (Marley) 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 Marley 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.
Marley is 8 km (5 miles) from Cronulla. If you plan a holiday in Illawarra, look for hotels and other accommodation in Cronulla. Cronulla has rooms for a wide range of budgets as well as car hire and transport links.
