The Lowdown
Alright folks, it’s Rusty here. Let’s have a look at what’s coming up for Southerndown.
Right off the bat, I gotta be straight with you – the next couple of weeks are looking pretty grim for a proper paddle. The surf is gonna be small and mostly on the wrong side of messy. We’ve got a long stretch of poor surf conditions ahead.
The first real chance of anything worth mentioning is the morning of Monday the 7th. We’ll see a 4ft swell from the WSW, but the period is a chunky 14 seconds, which is proper groundswell energy. The combined energy is moderate at 633. The wind is cross-shore from the NW, which is okay, but it’s a moderate breeze blowing a cross-chop across the surface. It’s not clean, but it’s the most energy we’ll see for a while. The afternoon looks worse with the wind swinging onshore.
For the rest of that first week, it’s a write-off. The wind is mostly cross-on or onshore, and the swell stays small or becomes weak and short-period. The morning of the 12th sees a tiny 2ft swell with light winds, but it’s cross-on, so not much to get excited about. The next week doesn’t bring much joy either, with more of the same small, choppy conditions.
There is one tiny glimmer. On the morning of the 16th of September, we get a 3ft swell from the WSW with a clean cross-offshore breeze from the ESE. The wind is light, so the surface will be clean. The combined energy is weak at 82, and the period is a short 7 seconds, so the waves will be small and weak, but it’s the only time in the whole outlook where the wind is actually working with us. It’s surfable, but very ordinary.
Honestly, for a spot like Southerndown, a blank run like this isn’t that unusual. The wind just isn’t playing ball. It’s a beach setup, and with the wind we’ve got, this might be more interesting for the kite crew than us paddle surfers. Keep an eye on the forecasts, but don’t get your hopes up for anything decent.
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.
