The Lowdown
G’day, I’m Rusty.
Alright, let’s be straight with you—this stretch isn’t shaping up to be anything to write home about. Over the next 16 days, the swell mostly stays small and messy, with the wind often working against us. There are a few moments where it cleans up, but nothing screams “drop everything and go.” The first real chance of anything decent doesn’t pop up until Tuesday the 18th, so the start of the period is a write-off.
Tuesday the 18th morning at Marley (Garie-Point) is the first flicker. It’s only 3ft of ESE swell at 7 seconds—short period, so not much push—but the wind goes glassy. That’s a rare treat, and the break is very consistent, so you’ll find something to ride, even if it’s small and weak. The combined swell energy is weak (134), so don’t expect power. It’s just nice to be out there with no wind chop.
Wednesday the 19th morning sees a little improvement. The swell drops to 2ft from the ESE, but the period stretches to 10 seconds, giving it a bit more shape. Light offshore NW wind at 5 km/h keeps it clean. Combined energy is still modest (180). Again, small, but clean and rideable for the more experienced crew—Marley is an advanced wave, so you’ll need to earn your turns.
Thursday the 20th morning is another small clean window: 2–3ft from the ESE, 7-second period, with a light cross-offshore NNW breeze. Combined energy is very weak (60). It’s surfable, but ordinary.
Friday the 21st morning offers a similar deal: 3ft from the ENE, short 6-second period, but clean with a light WNW offshore at 10 km/h. Combined energy is weak (82). The afternoon stays clean with a stronger offshore NW breeze at 25 km/h, but the swell stays small and short.
The standout, if you can call it that, is Sunday the 23rd morning. The swell picks up to 5ft from the S at 8 seconds—short period but decent height. Combined energy climbs to moderate (362). With a light WNW cross-offshore breeze at 10 km/h and clear skies, it’s the best-looking session in the whole outlook. Marley is an exposed point, so that south swell will wrap in nicely. It’s a little too big for beginners, but solid for advanced surfers. Crowds are possible here sometimes, so don’t expect to have it to yourself.
After that, the forecast gets a bit wild. Monday the 24th drops right back down, and then Tuesday the 25th sees a big jump in swell—8ft from the S at 8 seconds in the morning, building to 10ft from the S at 12 seconds in the afternoon. Combined energy goes strong to very strong (1024 morning, 2226 afternoon). That’s serious size and power, but the wind is cross-onshore and strong, creating lumpy, choppy conditions. This setup looks more interesting for kite surfing than paddle surfing—definitely not for the faint-hearted, and experts only if you’re feeling brave.
The rest of the period into late August and early September stays small, with occasional clean mornings but nothing worth chasing. The water temp at Marley is 63°, which is about 1° cooler than average for this time of year—pretty normal, nothing unusual.
So, bottom line: the best bet is Sunday the 23rd morning. It’s not perfect, but it’s the most promising session in a mostly quiet fortnight. Keep an eye on the forecast, because things can change, but for now, that’s your window.
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.
