The Lowdown
Alright, Rusty here, let’s talk about what’s coming up for Southerndown.
Right off the bat, I gotta say it: this is a flat spell. There’s nothing worth paddling out for over the next couple of weeks. We’re looking at a long dry run with no real swell to get excited about.
For the first week, from Wednesday the 29th right through to Tuesday the 11th of August, every single session is rated as poor. The swell is tiny, mostly between 0.3ft and 3ft, and the period is short, rarely getting above 8 seconds. The wind is a constant problem too – cross-onshore most of the time, often moderate to fresh, so the surface is choppy and lumpy. Even when the wind does go light or glassy, like Sunday the 2nd afternoon or Wednesday morning the 5th, there’s simply no wave energy to work with. The combined energy never breaks 100 – it’s mostly sitting in single digits or low double digits, which is weak.
We do have a little bump in combined energy on Saturday the 1st afternoon hitting 95, and again on Tuesday the 11th afternoon reaching 55, but with swell height still only 2ft and 2ft, and wind cross-onshore, it’s not going to clean up. The only standout in terms of conditions is a brief glassy period on Sunday the 2nd afternoon, but the swell is only 1ft and 8 seconds – not enough to push through.
For a beginner-friendly, fairly consistent spot like Southerndown, this is a frustrating stretch. It’s fairly exposed to a SW swell, but the ocean just isn’t delivering. The water temperature is about average for this time of year, so at least it’s not freezing when you’re sitting there waiting for nothing.
All in all, leave the board at home. There’s nothing on offer here. Forecasts can change, but right now, this is as quiet as it gets.
Rusty.

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.
