The Lowdown
Well, folks, it’s Rusty here, and I gotta be straight with you—this stretch is pretty grim. We’re looking at a long, drawn-out period of flat, weak surf with hardly anything to get excited about. The water temp is about average for this time of year, so at least you won’t be freezing while you stare at the ocean.
Let’s break it down. Starting now, Monday the 31st of August, through to the 11th of September, it’s a whole lot of nothing. Swell heights are tiny, barely 0.3 ft to 1 ft, with periods under 5 seconds—basically wind chop. The wind is all over the place, mostly cross-shore or onshore, and the wave energy is pitiful, with readings like 4 to 16 (weak energy). You’d be better off taking up kite surfing if you’re desperate for a fix, because the surf is just not happening.
There’s a glimmer on Saturday the 12th of September morning. Octagon House (Octagon) sees a glassy morning with a small 5 ft swell from the SSE, period 6 seconds, and the combined energy climbs to 181 (moderate). The wind is light, glassy, so it’s clean—but it’s still pretty ordinary. This is the best we’ve got, and it’s barely a 1 out of 10 for surfable waves. It’s a beginner-friendly size, but with that short period, don’t expect much push.
Then Sunday the 13th of September morning offers another glassy moment, with 5 ft from the SE, period 6 seconds, and energy at 127 (moderate). Again, it’s clean but hardly a standout. The rest of the 16 days? More poor conditions, with onshore winds and tiny waves. The last day, Tuesday the 15th of September morning, brings a clean, offshore wind from the NW, but the swell is only 1 ft from the SSE—just a ripple.
Honestly, there’s no real standout here. The best bet is early Saturday the 12th, but even then, it’s a weak offering. Crowds are possible at Octagon House, but who’s gonna bother? This is a blank run, and for this area, it’s not that unusual. Forecasts can change, but for now, I’d save your energy.
Rusty.
