The Lowdown
Alright, Rusty here. Let’s have a proper look at what’s coming down the line for Marley.
We’re kicking off Tuesday the 11th of August, and honestly, the start is a bit of a mixed bag. The swell is inconsistent and choppy, and winds are all over the place. You wouldn’t want to rush out for it. Wednesday the 12th, though, sees a change for the better: morning brings a clean 4ft south swell with a gentle offshore breeze from the WNW. The combined energy sits at 256 (moderate), and that offshore wind will make for some tidy, lined-up waves at this point. This is a solid, clean option for the advanced surfer who knows Marley. The cross-off wind in the arvo will still be surfable but not quite as crisp.
Thursday the 13th has a bit more size at 6ft from the south, but the wind swings cross-shore in the morning, making it a bit lumpy. The energy jumps up (850), which is moderate to strong, but don’t expect perfection. By the arvo, it’s onshore and messy – best avoided.
Friday the 14th is an early-morning window again: a measly 4ft from the south, but the wind is nearly dead, just a slight air, and it’s clean. It’s small, but the wave quality will be there for a few fun ones. Crowds are sometimes an issue here, so a weekday morning is your friend.
Then we hit a long, frustrating stretch. From the 15th of August all the way through to the 25th, it’s pretty much a write-off. Strong onshore winds, lumpy conditions, and poor surf quality dominate. Saturday the 15th and Sunday the 16th are particularly ugly, with fresh onshore winds over a lumpy 6ft to 5ft swell. The 17th through the 20th are all onshore and messy, with swells around 5ft to 7ft but terrible wind. Even the wave energy numbers (up to 932) don’t mean a thing when the wind is that wrong. This is a definite gap for paddle surfing – honestly, that setup with the cross-on wind and lumpy sea looks way more interesting for kite surfing than anything else.
Finally, we get a light at the end of the tunnel. Wednesday the 26th of August morning is the standout of the whole outlook. We’re looking at a 8ft SE swell, which is solid, with a moderate offshore wind from the NNW. The period is 8 seconds, so it’s not a super long groundswell, but the energy reading is strong (814). The forecast calls for “very good surf conditions.” This size is expert territory, and at Marley, this offshore wind will groom that swell beautifully. That’s the one to circle on the calendar. Later that day, the wind might shift, so get on it early.
So to sum it up: Wednesday the 12th morning is a clean, fun session, but the real winner is Wednesday the 26th morning. Get ready for that one, boys. Between now and then, keep your board in the car, but be ready for a lot of checking and shaking your head.
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.
