The Lowdown
Alright, let’s get into it. Rusty here, checkin’ the charts for the next couple weeks.
First up, we’re lookin’ at Manly-South Steyne. This reef setup is a sheltered spot, pickin’ up swell from the south. It’s an advanced wave, and it’s inconsistent, so you gotta be patient. The water temp’s sittin’ at 64°, which is bang on average for this time of year. No surprises there.
The week kicks off on Friday 24 July. The morning’s got a 5ft south swell, period 9 seconds, with a light offshore wind from the southwest right out of the gate. That’s clean, but the combined energy is only 313 (moderate), and it’s just surfable – nothin’ to write home about. The afternoon shifts to an onshore breeze, which is a no-go.
Saturday 25 July, the morning is clean with a cross-offshore wind, but the swell is a bit mixed up. The period drops to 11 seconds, energy a bit better at 590 (moderate), but it’s still only marginal. Afternoon gets ruined by cross-on wind.
Now, Sunday 26 July is where it starts to get interestin’. The morning has a 6ft south swell, period 11 seconds, and a southwest offshore wind blowin’ at 9 mph. The water’s glassy, clean, and the energy jumps to 651 (moderate). This is the best of the first week – a solid, clean wave for the advanced crew. The afternoon, though, gets chopped up by the sea breeze.
Monday 27 July is a smaller day, with a 4ft south swell, period 9 seconds, and clean but weak energy at 206. Afternoon goes onshore and flat.
Tuesday 28 July and Wednesday 29 July are a write-off. Swell drops to nothing – 2ft and 0.3ft. The energy is pitiful (52 and 15). You’re better off stayin’ home.
Thursday 30 July brings a pulse. The morning has a 6ft south swell, period 10 seconds, and the energy rockets to 1248 (strong). That’s a lot of juice. But the wind is 16 mph from the south-southwest, cross-off, so it’s clean but the swell is big, over 5ft. Too big for beginners, and with that reef, it’s only for the experts. It’s marginal, not a standout.
Friday 31 July fades out – 4ft and 4ft, clean but weak.
The first weekend of August, 1st and 2nd, is tiny. Swell under 3ft, energy under 150. The morning of the 1st has a light offshore, but it’s just not enough.
We hit a big gap. From the 2nd to the 5th, it’s flat or junk. The 3rd and 4th are particularly poor – 0.7ft with a 14-second period on the 3rd? That’s a long-period groundswell but zero size. The 4th has a 5ft south swell but with a 6-second period – that’s short, weak, and messy.
The real standout is Thursday 6 August. The morning has a 6ft south swell, period 8 seconds, with a light offshore wind from the west-southwest at 6 mph. The energy is 549 (moderate), and it’s clean. This is a good, solid wave for the advanced crew. The afternoon gets cross-on, so get it in the morning.
Friday 7 August is also a good one. Morning has a 5ft south swell, period 7 seconds, with a 9 mph offshore wind from the west. Energy is 481 (moderate), and it’s clean. Another solid morning session.
Saturday 8 August is the last day with any life. The morning has a 3ft south swell, but check the period – 12 seconds. That’s a long-period groundswell, and it’s clean with a light offshore. Energy is 255 (weak to moderate). It’s surfable, but not a standout.
So, for the best on offer: Sunday 26 July morning is the pick of the first week – clean, solid 6ft, and good energy. For the second week, Thursday 6 August morning and Friday 7 August morning are the standouts. Both are clean, offshore, with decent size and moderate energy. Get in early before the seabreeze ruins it.
One last thing – this spot is inconsistent, so when it’s on, it’s on. Crowds are possible, so be ready for a few locals.
Rusty out.

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