The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaping up for Marley. It’s a bit of a frustrating start, but there’s a light at the end of the tunnel.
The whole 16-day window is a mixed bag, with a lot of wind-ruined sessions and only a few real windows of opportunity. The water temp is sitting at 64°, which is about average for the time of year, so no surprises there.
The first few days are a write-off. Wednesday the 9th and Thursday the 10th are blown out with strong, shifting cross-onshore winds, with the swell energy jumping from a moderate 171 up to a massive 1027 on Wednesday afternoon. That’s a lot of raw power, but it’s messy as hell. Friday the 11th morning is barely a marginal 2/10 with a 6ft S swell and 10 second period, but the wind is still cross-on, so it’s not worth getting excited about.
The first real stand-out is Saturday morning, September 12th. The wind swings light and cross-offshore from the NNW, cleaning everything up. The swell is a small but clean 4ft from the S with a nice 12-second period, giving the waves some shape and energy (539). This is the pick of the first week. It won’t be huge, but it’ll be fun on the point. Crowds are possible here, so get out early.
Sunday the 13th morning is also worth a mention with a similar clean 3ft S swell and light cross-off breeze, but it’s a touch smaller.
After that, we hit a dry spell. The surf drops off and the wind gets messy again. There’s a big pulse of swell on the 19th and 20th, but the wind is cross-on across the board, ruining the quality. The 19th morning sees a 7ft S swell with 10-second period and a combined energy of 967, but it’s chopped up by moderate cross-onshore winds. That’s kite-surfing territory, not for a paddle.
The second week finally offers another promising call. On Wednesday the 23rd, the morning brings a 5ft NE swell with an 8-second period and clean conditions from a light north wind. The combined energy is 327. It’s a moderate swell, but the clean conditions make it a solid option. Then on Thursday the 24th morning, a bit more size rolls in: a 6ft S swell with 9 seconds, and the combined energy hits 627. The wind is light and cross-shore, so it should be surfable, though the report says it’s marginal. It’s a long-range call, so don’t bank on it, but it’s worth keeping an eye on.
Overall, the best bet is Saturday the 12th morning. It’s not a monster, but it’s the cleanest, most playful wave of the whole forecast.
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.
