The Lowdown
Alright, I’m looking at the charts for the next couple of weeks, and I gotta be straight with you – it’s a quiet spell for Southerndown. The swell is tiny for the first week and a half, so don’t be in a rush to grab your board.
Right now, through the 14th of July and well into the next week, we’re looking at waves barely pushing 0.7 ft – mostly from the WSW and SW but with super short periods, or really long period stuff that just doesn’t have any push. The combined energy is sitting in the low teens and single digits for most of that time, which is basically flat. The water is running at 67° and is a whopping 7° warmer than normal for this time of year – that’s very unusual, but it doesn’t help the waves.
We’ve got a solid gap of about 12 days with no real surf on offer. It’s a stubborn stretch. The wind is mostly cross-off or glassy on a few mornings, like the 17th and 18th of July, but with only 0.3 ft to 0.7 ft of swell, it’s just a lake. Clean, but flat.
The one glimmer of hope comes at the very end of the run. Monday the 27th of July morning, we finally see something. The swell bumps up to 5 ft from the WSW, with a period of 7 seconds, and the combined energy kicks up to 327 – that’s moderate energy. The wind is light and cross from the SSE, so it’ll be a bit bumpy but rideable. This is the standout of the whole outlook, but it’s far out and still uncertain. On Tuesday the 28th, it drops off again with onshore wind and rain showers, so that Monday window is your best bet.
Honestly, it’s a tough couple of weeks. If you’re desperate, the 27th morning is the only time to even think about it.

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.
