The Lowdown
Right, take a seat and listen up. This is Rusty, and I’ve been staring at the charts for Southerndown.
Well, it's a tale of two halves. For the first week and a half, it’s flat and angry. You’re looking at a long stretch from Sunday the 26th right through to Monday the 3rd of August where there is basically nothing worth paddling out for. The wind is a constant cross-onshore, and the swell is either tiny or completely gutless – that combined energy reading barely gets into the double digits most days. The water is currently a very unusual 69°, which is *much* warmer than normal for this time of year. Weird, but true.
Then, around Tuesday the 4th of August things try to wake up. A pulse of WSW swell pushes in, but the wind is still a fresh cross-onshore making it lumpy. The energy builds into a moderate reading of 237 and then 312, but the conditions just aren't there to make it enjoyable. That carries on into Wednesday, but you still can’t get a wave without the wind messing it up.
But hold on. Thursday morning, the 6th of August, is where you need to be sharp. It’s not the biggest, but that’s a proper turning point. We’ve got a 5 ft swell from the WSW, and for the first time in ages the wind comes light from the ENE – that is a clean, cross-offshore breeze. The energy is healthy (406). It’s not a perfect score, but it is the best looking window we’ve got.
The real standout, though, is Saturday morning, the 8th of August. That’s the one to circle on the calendar. The swell jumps to 6 ft from the SW with a 9-second period, the combined energy is a strong 505, and look at that: glassy conditions. A slight air from the NE. That is the window for a clean, punchy session at Southerndown. It's big enough for a good push but not too big for a strong beginner, and the conditions will be about as good as they get. Get in the water then.
After that, the wind shifts back onshore and the swell fades again on the Sunday, so don't sleep on that Saturday morning. For a break that is fairly exposed to the SW, we just need the stars to align on that one morning.
Rusty.

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.
