The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaping up.
Straight up, for the next 16 days, we’re looking at a pretty flat spell. There’s a long stretch of nothing to get excited about, so don’t be planning any surf trips just yet. The first real chance of anything half decent doesn’t roll in until Wednesday the 9th of September, and even then, it’s not a standout.
The whole period starts with a big gap. From Sunday the 30th of August all the way through to Tuesday the 8th of September, it’s basically a no-go for surfing. The combined energy is tiny, usually in the single digits, and the swell heights are barely a ripple. We’re talking 0.3ft to 2ft at best, with short periods of 4 to 9 seconds. That’s blown-out dribble, not surf. The winds are often onshore or cross-shore, and the word “poor surf conditions” is all over it. If you’re a kite surfer, maybe have a look on the 9th, but for a paddle, forget it.
The only real bump in the road comes up on Wednesday the 9th of September. The morning shows a bit of life with a SE swell pushing 4ft, period of 5 seconds, and combined energy hitting 116 (moderate). The break is Octagon House, exposed to that SE direction. The wind is cross-shore at 12 mph, which creates a cross-chop, so it’s not going to be clean. The afternoon sees the swell bump to 4ft, but the wind swings cross-onshore at 16 mph, making it choppy. This is a beginner-friendly break, but these conditions are a bit messy for a learner. The swell direction is from the S, which is off the optimum for this spot (SE being the best). So, it’s the biggest we’ll see, but it’s not the best quality. Water temp is about average for the time of year, nothing unusual.
After that, it fades back to small, weak, and onshore chop for the rest of the window. There’s nothing in the second week that’s worth highlighting. The best bet? If you’re desperate, Wednesday the 9th of September at Octagon House, but keep your expectations very low. It’s the only game in town, and it’s not a good one.
Rusty, signing off.
