Alright, I'll be honest with you, it’s a tough stretch ahead for Southerndown. We're looking at a solid 16 days, but honestly, there's not a single session I'd get in the water for. The data here shows the swell is flat and weak, barely registering above 2ft, and even that tiny bump on Sunday the 5th of July is messy and cross-onshore. The wave energy is way down, with values like 52 (moderate energy) and then dropping to single digits for most of the run. The water temperature is sitting at 66°F right now, which is a huge 7°F warmer than normal for the time of year—so that's a bit of a weird one to feel, but it's not going to help the waves.
The first couple of days, Sunday the 5th and Monday the 6th, have a little bit of knee-high swell at 2ft to 2ft, but it's coming from the W and WSW with a short period of 6 to 9 seconds, so it's weak and won't hold shape. The wind is cross-onshore and choppy, so forget about any clean lines. By Tuesday the 7th, it's down to 1.0ft and the energy is just 18. It's a write-off.
From Wednesday the 8th right through to Monday the 20th, the swell never gets above 1ft, and most of the time it's tiny 0.3ft to 1.0ft dribble. You get a few glassy mornings—like Wednesday the 8th with a south 3 mph glass, or the 14th and 15th with calm winds—but there's nothing on the horizon to push through. The period jumps to 19 seconds on Monday the 13th, which is a very long groundswell, but the swell height is only 0.3ft, so it's just an ocean millpond.
This is a blank run, plain and simple. Southerndown needs a good SW groundswell with some size, and that just isn't coming. For kite surfers, there's a bit more wind around the 11th and 12th with fresh cross-shore breezes up to 19 mph, but for us paddle surfers, there is nothing to recommend.
Keep the board in the shed, mate. Forecasts can change, but right now, it's a long wait.

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.
