The Lowdown
Alright, Rusty here again. Let’s call it like it is – this forecast is a stinker. We’re looking at a 16-day stretch starting from July 13th, and you’re not going to find any worthwhile waves for over a week. There’s a gap from now until July 24th where the swell is tiny, the energy is weak, and the scores are all zeros. It’s a flat spell, plain and simple.
The first real chance of anything rideable shows up on Friday, July 24th, at Southerndown. There’s a small swell coming in from the WSW, around 3ft to 4ft, but the period is a short 4 to 5 seconds. That’s windswell, not the good stuff. The combined energy is still low, somewhere between 30 and 64. The wind is blowing cross-onshore with a fresh breeze, so it’s going to be lumpy and choppy. Not a day you’d mark on the calendar.
The water temperature is sitting at 66°F, which is a massive 7°F warmer than average for this time of year. That’s very unusual, so you’ll hardly need a wetsuit, but the ocean isn’t giving you anything else to work with.
There are no standouts here. No hidden gems. Just a long, empty stretch of flat, poor conditions. Keep your board waxed, but don’t get your hopes up. The forecast might change, but right now, there’s nothing to surf.
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.
