The Lowdown

Alright folks, Rusty here. Let’s look at what’s on the cards for Southerndown over the next couple of weeks. I’ll be straight with you – it’s a pretty quiet spell, with no real standout sessions to get excited about. The start of the period is a write-off, and there’s a long gap of nothing much happening.

The first glimpse of anything surfable doesn’t come until late. We’ve got a big gap from now until the 9th of August where the conditions are just too poor to recommend. The water is sitting at 69° – that’s much warmer than normal for this time of year, which is a real treat, but unfortunately the waves don’t back it up.

Over the first few days, from Monday the 3rd through to the 8th, it’s all onshore winds, small bumpy junk, and poor surf. The only real highlight is a brief moment on Friday the 7th morning when the wind goes glassy (calm) with a slight air, but the swell is tiny at 1 ft from the WSW with a short period of 5 seconds (combined energy of all swells: 10). It’s clean, but there’s nothing to ride.

Then on Sunday the 9th of August, things get a little better. The afternoon sees a glassy calm with 3 ft of 7-second swell from the W (combined energy: 71). The conditions are glassy, and the waves are surfable, but mind you, they’re very ordinary. It’s the best we’ve got, but it’s not a day to call in sick for. The swell direction is SW, which is the optimum for Southerndown, so the break should be working, but the size is small and the period is short. This is a beginner-friendly spot, and with the clean conditions, it could be a fun little session for someone learning.

After that, from Monday the 10th right through to Tuesday the 18th of August, it’s back to the same story: tiny, weak, onshore slop. The combined energy of all swells directed here never gets above 36, and most days it’s in the single digits or low teens. The wind is mostly cross-on from the W or WSW, so the water will be choppy and lumpy. There’s nothing to chase.

So, the honest truth is that there’s no real standout in this forecast. If you’re desperate, the best of a very poor bunch is the afternoon of the 9th of August, but don’t expect much. The long-range stuff is all promise-less. Keep your eyes peeled for a change in the forecast, but as it stands, it’s time to find something else to do.

Rusty.

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.
