The Lowdown
Alright mates, Rusty here. Let’s get real about Southerndown – the next couple of weeks are looking pretty grim. We’ve got a long stretch of poor surf, so don’t get your hopes up for any proper sessions.
The pattern is set from Saturday the 25th of July. The onshore winds are just relentless. We’ve got a weak combined swell energy (30) with a messy 3 ft wave from the west, but the period is only 4 seconds – that’s pure windswell. The water is a very unusual 69°, which is a huge 8° warmer than normal for this time of year, so you might be warm, but the wind is going to ruin it.
The west and northwest cross-on winds are blowing hard, hitting 25 mph on Sunday the 26th, making the 4 ft swell (combined energy of 184) a total washout. The wind eases a bit on Tuesday the 28th, but the swell drops to a tiny 2 ft with only 15 units of energy. We get a few days of tiny, grovelly waves right through the end of July and start of August, with the swell occasionally hitting 4 ft (combined energy of 89) on the 30th, but it’s still cross-on and choppy.
There’s a gap of several days where the numbers are just too small to even think about it. The only flicker of hope is on Tuesday the 4th of August, where we get a brief window of offshore wind from the south-southwest – that’s clean. But the swell is only 2 ft with a combined energy of 53, and it’s a short period. It’s a tease. The best chance for a wave comes later on Sunday the 9th of August, where the swell bumps up to 4 ft from the west with a period of 7 seconds and a combined energy of 232. That’s the most energy we see, but the wind is a fresh cross-on, so it’s going to be lumpy and messy.
For a beginner-friendly spot like Southerndown that’s fairly exposed to the southwest swell, this is a tough run. The constant cross-on wind means there’s no clean face to work with. If you’re desperate for a paddle, the Tuesday morning with the light offshore is your best bet, but keep expectations low. It’s a pretty blank run, and it’s not unusual for this area to get stuck in a pattern like this.
Rusty.

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.
