The Lowdown
Alright, grab a coffee and listen up. Rusty here.
I've been staring at the charts for our little corner of the coast, specifically at Octagon House. To be honest, it’s a rough stretch ahead. We're looking at a solid 16-day window with surf that’s tough to get excited about. There’s just nothing doing for a good chunk of that time.
The water temp is running a touch warmer than normal at 87°F, which is nice for a paddle, but that’s about the only bright spot.
The first real day to talk about is Wednesday the 2nd of September, but it’s not pretty. We’ve got a weak 2ft swell coming from the SSW with a short, choppy 5-second period. The combined energy is a meager 26, so it’s weak. Add in a risk of thunderstorms and a 16 mph cross-swell from the southwest, and you’ve got poor, messy conditions. Not worth paddling out.
From there, it goes from bad to worse. For the next two weeks, the swell stays tiny, mostly 1ft to 2ft, from the SSE and S. The period hangs around 4 to 6 seconds, so it’s all wind swell. The combined energy dips into single digits and low double digits, basically nothing. The wind is a constant problem, blowing onshore or cross-onshore from the south and southeast at 6 to 16 mph.
There are a couple of mornings, like Sunday the 6th and Monday the 7th, where it goes glassy, but the swell is still a pathetic 1ft. You might be able to catch a knee-high ripple on a longboard, but it’s not surf in any real sense. Everything is flagged as poor surf conditions, and every single rating is a 0.
Forget the second week; it’s more of the same. A few spots show the swell trying to push up to 2ft around the 13th and 14th, but the wind is still cross or onshore, making a mess of it. There’s no standout swell, no clean window to aim for.
Honestly, this is a classic flat spell for the area. That can happen. We just have to wait for the next system to roll through and hope the forecasts change. For now, leave the boards in the car.
Rusty.
