The Lowdown
Alright, Rusty here. Let’s break down what’s coming for our stretch.
We start off a little slow, but there are a couple of windows that’ll get you wet. The first real chance is Monday morning, August 31st, at Marley (Garie-Point). It’s small but clean – 3ft of south swell, glassy conditions, and barely a whisper of wind from the NNW. Water temp is 64°, right where it should be for the season. The combined energy is moderate at 233, so not cranking but rideable. This is a very consistent point break that’s open to the south, which is exactly what we want. Watch out for crowds, though – it gets busy here sometimes.
Monday afternoon the wind goes NE and picks up, messing it up, so the morning is your window.
Tuesday, September 1st, stays small with the same 3ft south swell, but the period stretches to 11 seconds – that’s longer-period groundswell, meaning more punch and better shape on a point. The morning is clean with a cross-offshore NNW breeze, and Tuesday afternoon is also clean, though the wind is a bit more cross-off. Both are surfable, but nothing special.
Wednesday, September 2nd, the swell drops a bit more – 2ft in the morning, 2ft in the afternoon – with offshore and cross-off winds. Energy is weak to moderate (159 and 123). Clean, but very ordinary.
From Thursday, September 3rd, through the end of the first week, the swell fades and the wind picks up, leaving us with a stretch of poor to unsurfable conditions. Friday, September 4th, has a brief morning window with 3ft of south swell at 12 seconds and light offshore wind – that’s decent for the size, clean and with some energy (290). But the afternoon wind cranks NE at 30 km/h and ruins it.
Saturday, September 5th, and Sunday, September 6th: Saturday is a washout with strong wind, but Sunday, September 6th, is the real highlight of the first week. The morning brings 5ft of south swell – the biggest yet – with zero wind, glassy conditions, and combined energy at 435 (moderate to strong). That’s the best of the first week. The period is 9 seconds, so it’s shorter period windswell, but on a point break it can still offer fun lines. 5ft is getting solid for beginners. Sunday afternoon the wind swings NE and chops it up.
The second week is mostly a bust. Strong winds, onshore slop, and a lot of poor conditions. Monday, September 7th, through Saturday, September 13th, is a long stretch of no-go surf – strong S and SSE winds, rain, blown-out and choppy. There’s a spike of bigger swell on the 12th and 13th with 7ft to 10ft, but it’s cross-on or onshore and brutal – more for kites than paddle boards.
The dry spell breaks on Monday, September 14th: a 4ft SSE swell with light cross-offshore wind and clean conditions. Energy is moderate at 405. Surfable, but not a standout.
The best of the late period is Tuesday morning, September 15th. Glassy conditions, 3ft SSE swell, light air from the ESE, combined energy at 201. Small but clean as a whistle. The swell direction is a touch east of the optimum, but on a point break that can still wrap in nicely.
So, the standout sessions: Sunday morning, September 6th, for the biggest clean swell, and Tuesday morning, September 15th, for glassy small waves. The rest is mostly average or unsurfable. The second week has a long gap from the 7th to the 13th with no good options.
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.
