Alright, Rusty here. Let's have a look what's cookin' for Southerndown over the next couple of weeks.
Straight off the bat, I gotta be honest with ya. This is a tough one. We're lookin' at a real flat spell for the foreseeable future. The entire 16-day run is basically one long stretch of tiny, poor surf. The first recommendation is for Thursday, 9th July, but even then, it's a struggle. We're talkin' ankle-snappers at best.
Now, for Southerndown, which is a fairly exposed beginner-friendly break, we've got a SW optimum swell direction, but the swell just doesn't show up. Water temp is a whopping 7°F warmer than average for this time of year – that's really unusual, so the water will feel like a warm bath, but that's about the only highlight.
Thursday the 9th kicks off with a measly 1ft from the WSW, period at 10 seconds, but the wind is cross-on from the West at 3 mph in the morning. It's just wind ripples and messy. Combined swell energy is weak at just 19. Friday the 10th cleans up a bit with a cross-off wind, but we're still stuck on tiny 1ft waves. Saturday the 11th is cleaner but even smaller at 0.7ft.
The whole second week, from Sunday the 12th right through to Friday the 24th of July, is a total write-off. We're talking swell heights barely cracking 2ft, periods all over the shop but mostly short period junk, and combined energy readings that are just pathetic. You'll see a few days with a clean cross-off wind, like Monday the 20th and Tuesday the 21st, but it's flat as a pancake. For a beginner spot, there's absolutely nothing to ride. The setup is so weak and the wind often strong enough to chop it up that it'd be more interesting for kite surfing than paddle surfing for most of this run.
So to sum it up, there are no good surf options in this 16-day window. It's a long, dry spell. For this area, a blank run like this is more normal during a flat summer pattern. Gotta wait for the next system to push some proper juice our way. Forecasts can change, but right now, leave the board in the garage.

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.
