The Lowdown
G’day, Rusty here. Let’s break down what’s on the cards for Manly. It’s a slow start, but the tail end of the forecast has a real cracker. Stick with me.
The first few days are lean. Saturday the 22nd has a tiny NE swell at 1ft with a short period of 6 seconds. Wind is messy and the wave energy is a weak 18. Not worth wetting a suit. Sunday the 23rd morning is glassy with a 5ft S swell and energy at 391 – surfable but ordinary. Afternoon wind goes onshore and ruins it. Monday and Tuesday are all poor conditions with small, weak swell.
Wednesday the 26th morning brings a 6ft NE swell, short period at 8 seconds, but strong energy at 722. Cross-off wind from the W at 9 mph keeps it clean. That’s a solid, punchy session. Thursday the 27th morning is clean with a 3ft ENE swell and offshore SSW wind at 6 mph – a nice clean window. Friday the 28th morning is similar, 4ft ENE, clean but nothing massive.
The big one is Friday the 4th of September. That S swell hits 10ft with an 8-second period. The energy is insane – 1393 in the morning and 1261 in the afternoon. The afternoon has light WNW cross-off wind at 6 mph and clean conditions. This is a big, powerful S groundswell hitting a sheltered point. It’ll be a beast. At 10ft, this is experts-only. Water temp is average for the season, so a 3/2mm wetsuit is fine.
The second week has a few other clean windows. Saturday the 5th of September has a 4ft S swell but the wind is strong at 16 mph – a bit of a wrestle. Sunday the 6th morning is better: offshore SSW wind at 6 mph with a 4ft E swell – clean and workable.
Manly is a sheltered point, so that big S swell on the 4th will wrap in clean. Crowds are often a factor, so expect a lineup on that day.
That’s the rundown. Lock in Friday the 4th of September.
Rusty.

Information about the Manly Surf forecast
The above surf forecast table for Manly provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Manly can be found by selecting the local surf guide option on the grey menu. Our Manly 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 (Manly) 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 Manly 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.
