The Lowdown
Alright folks, Rusty here. We’ve got a long look ahead at Southerndown, and I’ll be honest with you right off the bat: it’s a grim stretch. The entire 16-day window is a write-off for proper waves. There’s a long gap of nothing but poor surf conditions from the start all the way through to the 23rd of August. The water is sitting at a very unusual 68.7°, which is a massive 7.6° warmer than normal for this time of year—like swimming in a bath, but that’s about the only positive.
For the first two weeks, we’re stuck with tiny swell (0.3ft to 3ft) and weak energy (often well under 100, with most readings in the single digits or low tens). The wind is mostly cross-onshore or choppy, so it’s messy and small. Even when we get a few glassy or clean moments on the 10th, 15th, and 16th, the swell is just too small to do anything with. There’s a brief pulse on the 12th morning with a 10-second period and 1.3ft, but the energy is still only 41 and the wind is clean—still not enough to ride.
The only time this spot even sniffs something surfable is right at the very end. On Monday the 24th of August, we finally see a bump in combined energy to 157 (moderate) with a 4.3ft swell from the WSW. The period is a short 7 seconds, so it’s windswell, not groundswell, but at least the morning has clean cross-off winds from the East and the afternoon goes glassy. It’s still only rated as very ordinary, and it’s the only day in the whole forecast that even gets a score above zero. For a beginner spot that’s fairly consistent, this is a rare blank run. The setup looks more interesting for kite surfing than paddle surfing on most days, honestly.
If you’re desperate, mark the 24th. But don’t hold your breath—it’s a long way out and the rest of the window is a dud.

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.
