The Lowdown
Alright, Rusty here, looking at the surf for the next couple of weeks down at Southerndown. It's a tale of two halves, and the first half is a real bummer.
We're staring at a big gap of nothing. From now until the end of July, the surf is flat and poor. The wind is mostly cross-onshore, making everything choppy and unrideable. You'd be better off waxing your board at home than driving down here.
Things finally show a pulse on Saturday, the 1st of August. We get a 4ft swell from the WSW with a 8-second period, and the combined energy is moderate. The wind is a gentle cross-shore from the SE, so it might clean up a bit. The model calls it marginal, but it's the best we've seen in a long time. The window is small though, as the afternoon gets blown out again.
Now, mark your calendars for Wednesday, the 5th of August. That's the real deal. A solid 7ft to 8ft swell from the WSW, with a 9-second period. The energy is strong to very strong, hitting 798 in the morning and 958 in the afternoon. The morning is the gem: glassy conditions with light rain and a slight air from the SW. That's a dream scenario. Because it's over 8ft, this is strictly for the experts. It's going to be heavy and powerful. The afternoon is a little less clean with a light cross-onshore breeze, but it'll still be pumping.
After that, it drops back to small, weak, and messy. So, the one true standout is that Wednesday morning, 5th of August, at Southerndown. It's a long way off, but if that glassy forecast sticks, it'll be a day to remember.
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.
