The Lowdown
Alright folks, Rusty here. Let’s be straight with you – the next couple of weeks are flat as a pancake around here. There’s no good surf on offer at all for the entire 16-day window. The finder tool came up empty, so we’re just looking at a long stretch of poor conditions. The only break on the list is Southerndown, but every single session comes back with “poor surf conditions” and a zero score, so I wouldn’t even bother getting the wetsuit out.
The main issue is the wind. For most of the next week, it’s blowing onshore or cross-onshore, mostly from the SW or WNW at 9 to 22 mph. That’s going to trash any little bump we might get. Swell heights hover around 2 ft to 4 ft for the first week, with short periods of just 5 to 10 seconds – that’s weak, choppy windswell with barely any grunt. The combined energy values are mostly in the low to mid double digits (64, 61, 65, 98), and even the peak around 349 on the 13th is still just moderate energy and crossed-up. Not worth paddling out for.
There is a pulse that tries to show up on Saturday the 20th – afternoon sees 8 ft of WSW swell with an 8-second period, and the combined energy jumps to a strong 746. But it’s coming straight onshore with a 19 mph SW wind, so it’ll be a messy, blown-out wall. At that size, it’s too big for beginners anyway, and with those winds, it’s only any good for experienced surfers looking for a beat-down, or honestly, it might be more fun on a kite. The water temp on the first slice is sitting at 67°, which is a whopping 6° warmer than normal – a very unusual anomaly, so you can leave the 5/4 at home, but you’ll still need a spring suit.
From the 21st onwards, it just fades away. By Wednesday the 23rd, we’re down to 1 ft with glassy conditions, but there’s zero energy (combined energy just 13). The standouts? There are none. Not a single day or break in this whole window deserves a call-out. It’s just a long, blank run. In this area, that happens sometimes – the forecasts can change, so keep an eye on it, but for now, don’t hold your breath. The only positive is that if you’re really keen, the last few days of the window (24th to 25th) have light ESE or E winds going cross-offshore with clean conditions on those tiny 1 ft leftovers, but you’d need a log and a lot of patience.
Stay tuned, but don’t get your hopes up.
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.
