The Lowdown
Alright, Rusty here again. I’m looking at the same 16 days, and I gotta tell you, it’s a grim picture. There’s no surf worth paddling for. The first few days are tiny and messy. That little pulse on the 5th of August shows a bit of size – 5ft to 6ft from the WSW – with combined energy in the 300s, but the wind is ripping from the W at 18 to 22 mph, cross-onshore. It’s just a lumpy, blown-out mess. The wave comment says “poor surf conditions” the whole way.
Then it’s a long, flat run. From the 6th of August through the 18th, the swell is barely 0.7ft, with most days sitting at 0.3ft to 0.7ft. The combined energy numbers are all in the single or double digits – 2, 4, 5, 11 – that’s as weak as it gets. There’s a glassy morning on the 9th of August with the wind from the SSE at just 3 mph, but the swell is only 0.7ft. It’s clean, but there’s nothing to ride.
Water temperature is about normal for this time of year. Southerndown is usually a fairly consistent spot, but this 16-day window has zero good options. It’s a blank run, and it’s just the way it goes sometimes. We’ll have to wait for the next forecast to change.
Rusty.

The above surf forecast table for Southerndown provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Southerndown can be found by selecting the local surf guide option on the grey menu. Our Southerndown surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

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.
