Alright folks, Rusty here. Let's take a look at what Southerndown has in store for us.
Honestly, straight up, this is a pretty grim outlook for the next couple of weeks. The wave energy is just too weak and the wind is mostly rubbish. We're looking at a long stretch of tiny, messy surf that isn't going to be worth getting wet for. The water is sitting at 65°F currently, which is a massive 6°F warmer than usual for this time of year – that’s really unusual and means you can probably ditch the wetsuit for a spring suit, but don't get too excited about the waves themselves.
For the first week and a half, there's almost nothing to write home about. From Saturday the 4th to around the 17th of July, the swell is constantly under 3ft, often down around 0.6ft to 1ft. The combined wave energy is in the low double digits or less than 100, barely a ripple. The wind is mostly a cross-onshore from the west, which will keep it choppy and lumpy. There are a few brief moments of glassy conditions – like the morning of Wednesday the 8th of July and the morning of Saturday the 11th of July – but with no swell to push through, it’s just flat and clean, not rideable.
We finally see a slight pulse at the very end of the forecast. Around the 18th of July, the swell climbs to about 3ft (99 combined energy) on the Saturday morning, and then 4ft (55 combined energy) on the afternoon of Friday the 17th of July, but it’s still a short-period windswell at 5-7 seconds. That short period combined with cross-onshore wind is going to be a messy, bumpy affair.
There is simply no standout day or break here. Any small bump on the 17th or 18th of July will be for the die-hards only, and even then, it’s going to be a battle against the chop. For now, leave your board in the car and enjoy the unseasonably warm water from the shore. The blank run is real, but forecasts can change.
Rusty.

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.
