The Lowdown

Alright folks, let’s get straight into it. Southerndown is the only spot on the cards, and to be honest, it’s a tough one for the next 16 days. We’re looking at a real flat spell of tiny, weak, and mostly messy surf. The finder’s giving us nothing recommended, so I’m not gonna sugarcoat it – this is a quiet period for the region.

The first session that’s even worth a look is a long way off, on the morning of Saturday, 26 July. There’s a tiny bump of 2ft from the WSW, with a period of 6 seconds, and the combined energy is a weak 27. The wind is a clean cross-off from the NNW, so it’ll be clean, but honestly, it’s barely a wave. The water temperature is a whopping 69°F, which is *much warmer than normal* for this time of year – that’s an 9°F anomaly, so it’s quite the surprise.

That Saturday afternoon sees a bit more size, hitting 3ft from the west, but the period is still short at 6 seconds, and the energy picks up to 46. Problem is the wind swings to a fresh cross-shore from the NW, making it lumpy. Not great.

The only real standout in the whole 16-day window is Monday morning, 27 July. We get a 3ft west swell, still short period at 6 seconds, but the combined energy finally climbs into the moderate zone at 143. It’s a cross-on wind from the WNW at 12 mph, so it’ll be choppy. For a beginner-friendly break like Southerndown, 3ft is about the top end of comfortable, so it’s not for the faint-hearted, but it’s the biggest and most energetic wave we’ll see. The poor surf quality rating is a downer, but it’s the best we’ve got.

After that, it’s back to tiny, weak, and blown-out conditions through to 4 August. The morning of 30 July and 31 July offer some clean, cross-off winds, but the swell is a pathetic 0.3ft with a long period of 10 seconds – that’s a groundswell, but there’s just no height to it. The energy is laughable at 2-4.

Honestly, this is a blank run. For Southerndown, these long flat spells are not unusual. The forecasts can change, but as it stands, the only day to even consider paddling out is Monday, 27 July, and even then, it’s a gamble. The bigger westerly swell on 2-4 August (2-2ft) is completely blown out by strong onshore winds – that setup would be more interesting for kite surfing than a paddle board.

Stay patient, wait for a change in the charts.

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.
