Alright, Rusty here. Let's have a look at what's coming our way.
Straight up, I gotta be honest with you – this forecast is a tough one. We're looking at a long, dry spell with barely a ripple to get excited about for the next couple of weeks at Southerndown. The water is sitting at 65°F, which is much warmer than normal for this time of year, but that's about the only highlight.
We start off on Saturday the 4th of July, but there's nothing doing. Swell is a weak 3ft from the west with a short period of 6 seconds, and that 30 km/h westerly wind is making a mess of things. The combined energy is only 116 (moderate wave energy), but it's gonna be lumpy and poor. It stays poor right through the first week. Swell drops to 2ft and then even smaller. Winds stay onshore or cross-onshore, keeping the surf choppy and unrideable. There's a clean morning on Thursday the 9th with a light cross-offshore breeze, but the swell is a measly 1.0ft. Not enough to do anything with.
The second week doesn't offer any hope either. The best we see is a bit of glassy calm on Saturday the 11th of July with a 1ft swell, but again, it's just too small to break properly. From there, it's practically flat. Swell heights drop to 0.3ft and 0.7ft with combined energy values sometimes in the single digits – that's weak wave energy. Even when the wind goes clean and offshore, there's just no power in the water.
So what's the call? Honestly, for the whole 16-day window, there are no standout days. There's no surf worth paddling out for. It's one of those spells where you're better off checking the forecast another day. For a spot like Southerndown, this kind of blank run isn't totally unheard of, but it sure is frustrating.
Keep the faith, check back in a few days – things can always change.

Information about the Southerndown Surf forecast
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. If you surf the same spot (Southerndown) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
