The Lowdown
Alright, mate, I’m not gonna sugarcoat it – this stretch is a real flat spell. The data’s showing a big gap of nothing much for the first two weeks. The first half of the outlook is dominated by tiny, weak swell and a lot of cross-onshore wind, leaving the water messy and the waves small and poor. For the first two weeks, the combined swell energy is weak, barely cracking 62 (moderate end of weak) on the best day, and most days it’s below 50. The water temp is sitting at 86°F at the start, which is about 2°F warmer than usual for this time of year – a bit toasty, but nothing wild.
The first real surf worth paddling out for doesn’t show until the very end of the run. The best option on the whole board is Octagon House on Saturday morning, August 22nd. We’re looking at a tiny 1.0ft swell from the SSW, but the wind is a light cross-offshore breeze from the WSW, which will make it clean. The period is a short 4 seconds, so it’s just small, weak windswell, but it’s the only session with clean conditions. The combined energy is a measly 3 (weak), so you’re not getting any power. For a beginner, this is about as safe as it gets, but you won’t be doing much more than floating around. The break is fairly consistent, but crowds are possible. It’s exposed to the SE, so that tiny SSW swell has to wrap in, which makes it even smaller. That Saturday morning is the only real standout – and it’s a small one.
The rest of the period is a write-off. For the first 12 days, every single session is flagged as “poor surf conditions.” The wind is onshore or cross-onshore, and the swell is below 3ft with short periods. The afternoon of the 20th (Thursday) sees a bit more period at 8 seconds with a 2ft swell from the SSE, but the wind is onshore from the SE, so it’s blown out. It’s a tough run.
