The Lowdown
Alright, Rusty here. Let's take a look at what we've got coming up over the next couple of weeks at Southerndown. I'll be straight with you, it's not looking like a classic stretch, but let’s break it down day by day.
The problem right from the start is that there's basically no surf worth paddling out for. We’ve got a long, quiet gap. For the first week and a half, from Saturday 25 July all the way through to Monday 3 August, it’s flat or plain ugly. Swell is tiny, mostly under 3ft, with weak energy readings in the low single digits – like 2 or 5 – and that combined energy never cracks three figures. The wind is almost constantly cross-onshore, making for choppy and lumpy conditions. Honestly, for the first 10 days or so, you’re better off keeping the board in the van.
Now, there is a tiny glimmer toward the end. On Tuesday 4 August, we finally see a little pulse. It’s nothing to shout about, but compared to the dead zone before it, it’s something. The morning of 4 August brings a small SW swell at 2ft with a period of 8 seconds, and the combined energy climbs to 68 – still weak but a step up. The wind goes offshore from the NNE at 16 mph, which cleans things right up. This is a classic beginner-friendly window: small, clean, manageable. The afternoon sees that swell drop to 2ft with offshore winds from the NE at 19 mph, still clean but smaller.
After that brief moment, it fades again. From 5 August right through to 9 August, we’re back to tiny surf, with swell heights mostly 0.7ft to 1.0ft and combined energy barely breaking 20. Winds are messy again, cross-onshore or cross, and the period stays short.
So, if you’re desperate for a paddle, Tuesday 4 August morning is your only real look. The water is notably warm – sitting at 69° with a +8° anomaly, which is much warmer than normal for this time of year, so it’s pleasant if nothing else. But overall, this is a long, flat stretch. For Southerndown, a blank run like this isn’t totally out of the ordinary, so don’t lose hope – forecasts can change.
Stay patient.

A general guide to surfing at Southerndown can be found by selecting the local surf guide option on the grey menu.

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.
