The Lowdown

Alright, folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.

To be straight with you, the outlook is pretty grim for a long stretch. We’re looking at a solid ten days of barely a ripple, so don't even bother waxing up until we get into the second week. The first real action worth mentioning doesn't show up until Monday the 24th of August, and even then, it’s a mixed bag.

The best bet in the whole forecast is Southerndown on Monday the 24th of August. The afternoon session is the standout. We’ve got a solid 5ft swell coming from the WSW, and the wind is cranking offshore from the NNE at 19 mph. That’s gonna groom it up clean. The combined energy reads a solid 206 (moderate), so there’s a bit of push behind it. That size is right on the edge for a beginner, so the more experienced crew will be in their element. The next morning, Tuesday the 25th, is also a decent shout with 3ft from the WSW, clean cross-off wind from the NNW at 12 mph, and energy at 101 (moderate).

Before that, we’ve got a couple of mornings that are clean but tiny. Sunday the 16th of August morning is glassy—wind from the SSE at 3 mph, but the swell is a pathetic 1ft. The water temperature is a very unusual 69°F, which is over 7° warmer than normal for this time of year, so you might not even need a spring suit, but you’ll be bobbing around with no waves.

From the 11th right through the 23rd, it’s all poor surf conditions. There are a few clean moments, like the 15th and 20th, but the swell is so small (1ft) it’s not worth the drive. The wind stays messy, often cross-on or choppy, especially in the afternoons.

Then, into the last week, we get a bit of a pulse. Wednesday the 26th of August morning brings 5ft WSW swell, but it’s described as "surfable waves but very ordinary conditions." The energy is a solid 194 (moderate), but the period is short at 6 seconds, so it’ll be a bit lumpy and weak. The wind is clean, though, from the ESE at 9 mph. That afternoon, the swell pushes up to 6ft, but it’s cross-on and the waves are just marginal. At that size, it’s getting into expert territory, but the quality is poor.

So, to sum it up: if you’re itching for a paddle, the main event is Monday the 24th of August afternoon at Southerndown. The rest of the window is a write-off or very ordinary. Keep your eyes peeled for the forecast to change, because it’s been a quiet spell.

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.
