The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for the next 16 days down at Southerndown.
To be straight with you, it’s a tough stretch. The first week and a half is pretty much a write-off for any decent paddle surfing. The wind is relentless, mostly cross-onshore, and the water is a balmy 68°—that’s a whopping 7° warmer than usual for this time of year, which is very unusual. The swell keeps coming but it’s wind-affected and lumpy. We’re looking at combined swell energy that mostly sits in the low to moderate range. It’s just not clean.
The only real glimmer of hope comes in the second week. On Monday, September 14th and Tuesday, September 15th, the wind drops away. Monday morning is glassy, with a 3 ft swell from the WSW at a period of 9 seconds. The combined energy is a modest 143, but with that glassy surface, it’ll be the cleanest we’ve seen. Tuesday morning is also glassy, with a 3 ft swell from the same direction and period, and energy of 103. It’s small, but it’ll be rideable and ordinary.
That’s the best we’ve got, and it’s not much of a standout. For a beginner spot, the swell never gets too big, but the wind just kills it for most of the run. If you’re desperate, go for the glassy windows on Monday or Tuesday morning. If you’re after something more exciting, you might be better off looking at a kite for the many windy days.
Rusty.
