The Lowdown
Alright folks, Rusty here. Let’s be straight with you – the next couple of weeks are looking pretty flat and frustrating for Southerndown. We’ve got a long stretch of small, weak surf and a lot of wind chop to contend with. If you’re fiending for a wave, you’re going to have to be patient.
We’re looking at a run of poor conditions kicking off the period. Monday and Tuesday are essentially a write-off, with tiny, weak waves and some cross-shore winds that are going to make things messy. The swell energy is just pathetic, reading single digits and low twenties. The water temp is a notable 69°F, which is a solid 7°F warmer than usual for this time of year – that’s a real anomaly, so you won’t need a thick suit, just a whole lot of hope.
The mid-week doesn't offer much relief either. We finally see a bit of a bump on Wednesday the 13th, with the swell pushing up to 2ft and the energy climbing to 97. It’s surfable but far from inspiring. There’s a clean window Thursday morning with light offshore winds, but the swell is still tiny. You’ll be on a longboard, fighting for dribbles, not much else.
The following weekend and into the next week remains pretty bleak. There’s a brief moment of glass early Saturday morning, but the swell is down to 1ft. The wind is all over the place, and the swell energy stays weak. It's a long, dry spell. We’re looking at about a ten-day gap where there’s really nothing on offer. The wind is mostly cross or cross-on, making the already tiny surf a complete mess.
Now, let’s talk about the one glimmer of hope. Far out on the horizon, around Sunday the 23rd, there’s a pulse of proper swell on the charts. The model is showing the swell height jumping up to 6ft, and the combined energy of all swells directed here is a strong 463. That’s a real shot of energy. The direction is from the west, which is a good sign for this spot. The catch? It’s a long-range call, so don’t book the time off work just yet. The wind that morning is looking cross-on, which might chop it up, but the size is there. It’s going to be bigger, around 6ft, so it’s not for the faint of heart. With that size, it might be a bit much for beginners, but for the rest of us, it’s the only thing on the board that’s got any life in it. It's promising, but treat it as a "maybe" for now.
So, keep your board in the car, but don’t get your hopes up for the next week and a half. The surf will be back, but it’s going to take its sweet time.
Rusty out.

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