The Lowdown
Alright, Rusty here. Let's have a look at what's happening for us locally over the next couple of weeks.
To be straight up about it, this outlook is a tough one. We're looking at Octagon House, and for the entire 16-day window, it's a real struggle to find a wave worth paddling for. The swell is tiny, the period is short, and the wind just won't play nice.
The water is sitting at 87.1°, which is a touch warmer than normal for this time of year, so at least you won't be cold while you're bobbing around.
Starting from Saturday, August 22, and running all the way through to Sunday, September 6, every single session is marked as poor surf conditions. The combined swell energy is very weak, never cracking three digits, with most days hovering between 8 and 64. The swell height barely gets above 2 ft, and when it does nudge up to 4 ft on the afternoon of September 6, it comes with a period of just 5 seconds and onshore winds. That's just messy. The swell direction is mostly S or SE, but the optimum for Octagon is SE, so at least it's from the right quarter, but with no size or period, that doesn't mean much. The wind is almost always cross-onshore or directly onshore, with speeds of 12 mph or more chopping everything up. There are a few windows of light cross-off or light cross-shore winds, like the morning of August 27 with a clean look from a WSW breeze and a 9 mph cross-off, or the mornings of September 3 and 4 with a light cross-shore, but the swell is just too weak to offer anything ridable. The wave state for those mornings was described as "clean" or with small ripples, but the score remains zero.
There are no standout days here. The best you could hope for is a tiny, clean ripple on one of those light wind mornings, but there's no power, no push, and no real wave to surf. Honestly, given the persistent onshore wind and weak, short-period swell, this setup looks more interesting for kite surfing than paddle surfing. With the consistency being "fairly consistent" but the quality being this poor, a blank run like this is what we come to expect in this region when the weather patterns don't align.
There's just nothing to get excited about.
