The Lowdown
Alright folks, Rusty here. Gotta be straight with you – the next couple of weeks are looking pretty grim for a proper paddle. We’ve got a long stretch of weak, short-period windswell and a lot of onshore wind. Let’s break it down.
We start off with a real flat spell. From Thursday the 6th right through to the middle of the month, the numbers are tiny. The swell is barely 3ft at best, with a period of only 6 seconds, and it’s coming from the west. The wind is mostly cross-on or cross-shore, not doing us any favours. The wave energy is weak, sitting in the double digits (64), and the water is a wild 70°F – that’s much warmer than usual for this time of year, a real anomaly. But it doesn’t matter because the surf is just poor. This stretch is a write-off.
There’s a small glimmer on Wednesday morning the 12th. The wind goes glassy, and we get a little 2ft, 10-second pulse from the WSW, with a touch more energy (62). It’s still not much, but those glassy conditions are rare around here, so for a beginner looking for a tiny, clean wave, it might be the only window. But don’t get your hopes up.
We then hit another poor patch until the 15th and 16th. On Saturday the 15th morning, the swell picks up to 3ft from the WSW, period 7 seconds, and the energy creeps into the moderate range (111). Still, the wind is cross-on. Sunday the 16th afternoon sees the swell hit 4ft from the west, with energy at 134. But again, it’s a moderate cross-onshore breeze chopping it up.
The real kicker comes mid-week, on Wednesday the 19th. The morning sees a 5ft swell from the WSW, period 8 seconds, with strong energy (308). But the wind is onshore from the southwest at 19 mph. That’s a lot of water, but it’s going to be a messy, blown-out mess. For a beach break like Southerndown, that’s more of a kite-surfing setup than a clean paddle. It’s really only for the experts who don’t mind a beating, and even then, it’s not recommended.
The following Thursday the 20th holds similar size, 5ft from the WSW, but again with a cross-on wind. The energy is strong (284), but the quality is still poor.
So, what’s the best of a bad bunch? There’s no standout. If I had to pick one, it would be Wednesday the 19th for the pure size, but only if you’re an expert and don’t mind the wind. The cleanest conditions will be the glassy morning on the 12th, but it’s tiny. Honestly, it’s one of those periods where the forecast needs to change. We’re looking at over a week of nothing until the 19th, and even then it’s not great.
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.
