The Lowdown
Alright folks, it’s Rusty here, and I’ve got a flat spell to talk about for the next couple of weeks. We’ve got one break on the radar, Southerndown, but to be honest, the ocean is just not delivering the goods.
Right now, and for the next few days, it’s looking pretty grim. Southerndown is a fairly consistent spot, but the trade-off is we’re stuck with a persistent cross-onshore wind all week. The swell is tiny, mostly knee to waist high, around 1ft to 3ft, coming from the W or WSW, with a short, weak period of 5 to 6 seconds. The wave energy is next to nothing, barely registering. The water temp is a notable 69°, which is a massive 9° warmer than usual for this time of year – that’s way out of the ordinary. But with the wind ruining the surface, it’s just not worth paddling out. It’s a beginner break, but even beginners would be frustrated.
We get a brief change on Sunday, August 2nd, with a cross-offshore wind from the East, which cleans things up. But the swell drops even further, down to 0.6ft to 1ft, so while the surface is clean, there’s simply nothing to ride. The energy is a pathetic 9 to 13. It’s a tease.
Monday, August 3rd, sees a small bump in energy, hitting 108 by the afternoon, but the swell is still only 2ft from the SW with a short 8-second period, and the wind is straight back onshore. It’s messy and weak.
The best we see – and I use the term loosely – is around Tuesday, August 4th, and then again Sunday, August 9th. We get a little pulse of 4ft swell from the WSW, with energy readings climbing to 179 on the 4th and 229 on the 9th. But here’s the kicker: the wind is onshore or cross-onshore, blowing 9 to 22 mph. It’s choppy, lumpy, and just not surfable. The period is only 8 to 9 seconds, so it’s a weak, wind-affected swell. These are not standouts; they’re just the least terrible of a bad lot. For a beginner break, anything over 5ft is already challenging, and with that wind, it’s a washout.
There is a long gap of nothing worth mentioning. From August 10th onwards, the swell drops back to tiny 1ft to 1ft waves with weak energy, and the wind stays problematic. The 16-day window is a total write-off for Southerndown. There is no standout, no day to get excited about. The forecast can change, but right now, it’s a blank run that’s pretty normal for a summer lull.
Rusty.
