The Lowdown
Alright, Rusty here. Let’s have a look at what’s comin’ down the pipe for Marley.
To be straight with you, the first few days are a bit of a write-off. Tuesday the 25th and Wednesday the 26th are a no-go, with poor conditions and cross-off breezes messing up the lines. Thursday the 27th morning is still a struggle, that 6ft S swell is there but it’s cross-onshore, lumpy, and only marginal at best. The combined energy is moderate (635), but it’s not doing us any favours here.
There’s a bit of a tease on Friday the 28th morning. The swell drops to 5ft from the SSE, period jumps to 11 seconds, and we get a clean cross-off breeze from the WSW. The wave energy is moderate (643) and the conditions are set up for some very good waves. That’s the first real window of quality, but it’s only a morning session before the wind swings around and turns it to junk in the afternoon.
Saturday the 29th and Sunday the 30th are pretty average to poor. The swell is there but the wind is on it or cross-on, and it’s a mess.
Hold on, though, because there’s a real standout brewing. Monday the 31st morning is a beauty. The swell is small at 3ft, but it’s a long-period groundswell from the S at 18 seconds. That’s proper energy for a point break like Marley, and combined with a clean cross-off from the NNW, the conditions are looking very good. The wave energy is moderate (571). This is a gem for the experienced crew who know how to milk a long-period wave.
Then, Tuesday the 1st of September keeps the good run going. Another 3ft S swell, period back to 13 seconds, and we get a gentle offshore from the WNW in the morning. Clean, clean, clean. The afternoon stays clean too, with a moderate offshore. Good surf.
Now, here’s the big one. Thursday the 3rd of September. The swell jumps to 5ft in the morning, peaking at 6ft in the afternoon, all from the S with a 20-second period. That’s a massive groundswell, very long period, and the combined energy is strong (2225 to 2573). The wind is offshore both sessions, gentle in the morning, moderate in the afternoon. The conditions are rated excellent for experienced surfers. This is the standout of the whole forecast. If you’re advanced, you do not want to miss this. The water temp is normal for this time of year at 64°.
Friday the 4th and Saturday the 5th still have decent size, 5ft to 7ft S swell, but the wind gets cross-on or cross-shore, so it’s more marginal. The wave energy is still strong (1077 to 1458), but the quality takes a hit.
The second week drops off a bit. Sunday the 6th looks only marginal with a strong offshore wind that’s hard to paddle into. Monday the 7th morning is glassy, but the swell is tiny at 3ft. Tuesday the 8th is a write-off, and Wednesday the 9th is poor again.
Bottom line: Friday the 28th morning is your first clean session, but the real standout is Thursday the 3rd of September. That’s a day for the crew who know what they’re doing. The few days before that are also solid, but the 3rd is the one to circle.
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.
