The Lowdown
Alright mate, Rusty here. Let’s be straight with you – this next stretch is a quiet one for the Octagon House area. Over the whole 16-day run, from Wednesday the 19th of August right through to Thursday the 3rd of September, there’s not a single standout session. Every single check-in comes back with “poor surf conditions,” and the score is a flat zero the whole way through. The combined swell energy is weak, barely cracking double digits – mostly between 4 and 24 (weak energy). You’re looking at tiny, short-period windswell, mostly from the S or SE, with heights hovering around 1 ft to 2 ft, and periods of just 4 to 8 seconds. That’s mushy, gutless stuff.
The wind is no help either. Most mornings are cross or cross-off, but afternoons turn cross-onshore or onshore, leaving chop in the lineup. A few mornings – like Sunday the 23rd, Tuesday the 25th, and Wednesday the 26th – do have clean conditions with light offshore or cross-off breezes, but the swell is still too small and weak to do anything with. The water temperature anomaly is about average for the time of year, nothing wild.
Bottom line: there’s nothing here worth paddling out for. The whole 16-day window is a blank run. For an area like this, that can happen – it’s not unusual to have a quiet spell, and forecasts can always change, but as it stands, leave the board in the garage.
Rusty.
