The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks at Manly.
Right now, the surf is flat and ugly. We’ve got a stretch of nothing but poor conditions with small, messy waves and onshore breezes that’ll have you sitting on the sand. This dry spell runs from Sunday the 13th right through the end of the week. Tuesday the 15th might give you a tiny knee-high wave in the morning with a clean-ish look, but honestly, it’s barely surfable. The water temp is sittin’ around 63°, which is pretty average for this time of year, so no shock there.
Then things change. Wednesday the 16th morning sees a big pulse of south swell jumpin’ up to 10 ft. The energy is massive – you’re lookin’ at a combined energy reading of 1617, which is strong. But here’s the catch: the wind is howlin’ from the SSW at 22 mph. It’s offshore, so the waves will be clean, but 10 ft with that kind of wind is for experienced crew only. Thursday the 17th holds similar size around 10 ft, with moderate cross-off winds cleanin’ it up in the afternoon. Still, this is big, powerful stuff – only for the experts.
We get a bit of a lull Friday and Saturday, with smaller, messier swell around 4 ft to 3 ft. Not worth gettin’ wet for.
Now, here’s the standout. Monday the 21st morning. That’s the one to circle on the calendar. We’ve got a solid 10 ft south swell rollin’ in, with a combined energy of 1694 – that’s strong, powerful surf. The wind is light from the SSE at 9 mph, givin’ us clean conditions. For the skilled surfer, this is the best on offer. The swell direction is straight out of the south, which is just about perfect for Manly’s setup. This is a proper groundswell with a 10-second period, meanin’ solid, well-shaped waves with some decent gaps between sets. If you’ve got the chops, be there.
After that, Tuesday the 22nd drops back to chest-high waves with clean morning winds, but nothin’ special. Then we hit another quiet patch.
Look ahead to Saturday the 26th – we get a morning with glassy conditions and 6 ft of NE swell. The energy is moderate (440), and the wind is dead calm. That’s a sweet window for a longboard or a funboard, with clean, smooth waves. It’s not huge, but it’ll be perfect for a mellow session.
And finally, Monday the 28th morning brings another big south swell, 8 ft with a combined energy of 1508. Light cross-off winds will keep it clean. Again, this is for the experienced surfer, but the quality looks good.
Overall, the real highlights are Monday the 21st and Monday the 28th for the big, clean south swells. Saturday the 26th morning is a great call for a glassy, smaller day. The rest of the time, you’re better off waitin’ it out.
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.
