The Lowdown
G’day, Rusty here. Let’s break down what’s on the cards for the next couple of weeks. We’ve got a solid stretch of swell lining up, so it’s time to get keen.
The first proper waves arrive Monday, 14 September. The standout spot for the whole run is Super Suck – a reef and point break that loves a south-west groundswell. This is an advanced-only wave and it’s consistent, so you need your wits about you. Water temp is about average for this time of year, nothing wild.
Monday morning brings 6ft of SW swell with a 16-second period – that’s proper long-period groundswell, meaning clean, powerful lines, especially on a reef or point. Winds are light cross-off from the SE, making for glassy, clean conditions. Combined energy is strong at 1707. Monday afternoon stays clean with offshore ESE winds and the same 6ft SW swell, energy 1579.
Tuesday 15 September holds 6ft SW swell with a 15-second period, still very long and punchy. Morning is cross-off, afternoon picks up a moderate offshore breeze. Both sessions clean and excellent for experienced surfers. Energy sits in the 1300s.
Wednesday 16 September drops slightly to 6ft SW, but the period shortens to 15 seconds. Morning still clean with light cross-off winds. By afternoon, the quality fades a little – more marginal, but still surfable.
Thursday 17 September brings a 7ft SSW swell, period 14 seconds. Morning is excellent with light cross-off winds and clean faces. Energy is 1627. Afternoon gets a bit messy, but the morning session is worth the early start.
Friday 18 September sees the swell drop to 6ft SSW, then 5ft in the afternoon. Light winds keep it clean. Good, not great.
Saturday 19 September is smaller – 4ft in the morning with cross-shore winds, so a bit bumpy. Afternoon picks up to 4ft SW but with clean conditions and light cross-off breeze. Energy is moderate.
Now Sunday 20 September: a 6ft SW groundswell with a 16-second period rolls in, winds are near glassy from the SSW at only 3 mph in the morning. Energy jumps to 1958. Afternoon holds 7ft SW, same long period, light breeze. This is a standout day – clean, powerful, and consistent.
Monday 21 September keeps the run going with 6ft SW, 15-second period, light winds. Morning is excellent. Afternoon drops to 6ft SW, 14 seconds, still good.
Tuesday 22 September fades to 5ft SW, then a weird 4ft SSW swell with a 17-second period in the afternoon – very long period but small, so you’ll get long waits between sets. Clean but marginal.
Wednesday 23 September bumps back up to 7ft SSW with a 16-second period, morning energy at 1967. Winds are cross-off, but the call is marginal, possibly due to tide or shape. Still, there’s power there.
Thursday 24 September offers 6ft SSW in the morning, building to 7ft SSW in the afternoon, both with 15-second periods. Light winds, clean conditions, excellent surf. Energy 1488 to 1716. Another great day.
Friday 25 September is a ripper – 7ft SSW swell, 14–15 seconds, energy up to 2275. That’s strong wave energy. Winds are light to gentle, cross-off. Excellent conditions for experienced surfers all day.
Saturday 26 September holds 7ft SSW, 15–16 seconds, energy around 2000. Morning is marginal, afternoon is excellent. Still plenty of size and power.
Sunday 27 September sees 6ft SSW, 15 seconds in the morning, dropping to 6ft SSW in the afternoon. Light winds and offshore breezes in the afternoon make for clean conditions. Energy is over 2000 – very strong for the size.
Now, the real gem lands on Monday 28 September and Tuesday 29 September. Monday morning: 8ft SSW swell with an incredible 19-second period. That’s ultra-long period groundswell. Energy is massive at 4648. Winds are light, conditions clean. This is for experts only – over 8ft in the afternoon and absolutely pumping. Tuesday 29 September stays solid with 7ft SSW, 16 seconds, energy 2555. This is the best of the entire run.
So, if you’re only picking one window, make it Sunday 20 September through to Tuesday 29 September. The absolute standout is Monday 28 September at Super Suck – huge swell, very long period, clean, and all for the experienced crew. Crowds are sometimes an issue here, so get in early.
If you’re a beginner, steer clear when it’s over 5ft, and definitely stay out when it hits 7ft or more. This is advanced territory.
That’s the outlook. Stay safe, read the sets, and enjoy the ride.
Rusty.

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