The Lowdown
Alright, this is Rusty, and I’ve got the lowdown on the local stretch for the next couple of weeks.
Right off the bat, the next few days are a bit of a write-off. The surf is there, but the wind and conditions are just not playing ball. We’ve got a window opening up on the morning of Sunday the 13th that’s worth a look. Then things get proper messy, before a couple of real promising windows show up late in the second week. Let’s get into it.
We’re focusing on Marley (Garie-Point). A classic point break, very consistent, and pretty exposed to the swell. The water temp is sitting at 64°F, which is right about average for the time of year, so don’t expect a shock when you get in.
The first real standout is Sunday morning, the 13th. We’ve got a clean 3ft south swell rolling in at 11 seconds. The wind is light out of the north, giving us a nice cross-offshore breeze. The combined energy is moderate at 210, and the conditions are looking clean as a whistle. With a spot like Marley catching this swell from the south, it’s going to be lined up. Crowds can pop up here sometimes, but on a morning like this, with the swell size small and good, it’ll be worth the paddle.
After that, the wind goes onshore and the swell gets messy for days. It’s a real bummer. We get a big pulse of south swell mid-week, but it’s got a nasty 28 mph south wind on Wednesday afternoon, whipping up 13ft of raw, messy power. That’s a massive 2790 on the energy scale, but it’s only for experts and even they’ll be fighting a losing battle.
The next real highlight doesn't come until Friday morning, the 18th. The wind swings clean offshore from the northwest, light at 6 mph, and we’ve got a 3ft south swell at 8 seconds. The sea will be clean, and the energy is moderate at 241. This is a proper surfable morning, no doubt. You’ll get some fun little lines breaking down the point.
Then, a bit of a wildcard for Saturday morning, the 19th. We’ve got a 2ft south groundswell, but the period is a very long 17 seconds. The energy is still solid at 415. It’s glassy as glass with a light westerly breeze. This long period swell is going to wrap perfectly around this point. It might feel a little inconsistent between sets, but when it comes, the wave will have that deep, pushy energy. If you can sit deep, you’ll be in for a treat. The morning of the 19th is a proper standout for those who know what to look for.
The last good call is Friday morning, the 25th. A 3ft swell from the northeast with a 6-second period, so it’s a bit weaker and weaker energy at 140. The wind is light cross-off from the NNW, and it’ll be clean. It’s not the big one, but it’s a surfable option to end the run on a high note.
So, if you're looking for the best of the best, pencil in Sunday morning the 13th for clean small wave fun, and get excited for that long-period, glassy session on Saturday morning the 19th. That second one is the one I’m frothing on.

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.
