The Lowdown
Right then, let's have a look at what's on the cards for Southerndown over the next couple of weeks. I've gotta be straight with you – it's a tough stretch ahead. We're looking at a long, frustrating run of poor conditions right through the first week and into the second. The wind is mostly onshore or cross-onshore, and the consistent poor surf quality means there's very little to get excited about. There's a gap of several days here where it's just not worth paddling out.
The first real glimmer of anything halfway decent doesn't show up until Sunday, the 6th of September. It's not a classic, but it's the best we've got. On the Sunday afternoon, the wind drops right off and goes glassy. The swell is a weak 4.6 ft from the WSW, with a combined energy of just 150 (weak to moderate), and a short period of 6 seconds. It's surfable but very ordinary. Still, a glassy surface is a major positive for Southerndown, so it might be worth a look if you're desperate.
Then, we get a couple of clean windows on Monday the 7th and Tuesday the 8th of September. The swell is tiny though – only 2.3 ft and 1.6 ft – with weak energy (36 and 22). The wind swings offshore from the NNW and then goes glassy from the ESE. For a beginner spot like this, it would be clean but extremely small. Not much push.
That's about the pick of it, I'm afraid. The rest of the period is either blown out, too lumpy, or just flat. There's a nasty spell around the 10th of September with near gale-force winds and a big, messy 7.9 ft to 8.2 ft swell from the W and WSW. Combined energy hits 929 (moderate to strong), but with that howling onshore wind, it's a write-off for surfing – might be more of a kite-surfing day if you're into that sort of thing.
Stay keen, but don't hold your breath for this one.
