Octagon House Surf Forecast and Surf Report

G’day, Rusty here. Look, I’ve got to be straight with you – it’s a tough stretch ahead for Octagon House. We’re looking at a full 16-day window, and honestly, there’s hardly a wave worth paddling for. From Monday the 31st of August right through to Tuesday the 15th of September, the swell just isn’t showing up with any grunt. It’s a flat spell, plain and simple.

Starting Monday afternoon, we’ve got tiny 0.3 ft from the southeast with a short 8-second period – combined wave energy is a measly 4 (that’s weak). On top of that, the wind is a cross-onshore mess at 15 km/h, making it choppy. The water’s sitting at a warm 87°, which is a touch warmer than normal for this time of year, but that’s the only highlight because the surf is rubbish.

The next morning, Tuesday September 1st, there’s a brief flicker of hope with a light offshore breeze from the northwest and a clean-looking 2 ft from the east, but the period is a tiny 6 seconds and the energy only hits 17. It’s still classified as poor. By the afternoon, that wind swings south and picks up, ruining any chance.

Through Wednesday and Thursday, we see a slight bump to 2 ft on Wednesday morning, but it’s from the south with a 4-second period – just slop. The combined energy barely reaches 24. Every session is plagued by cross-onshore winds and chop. Friday through Sunday are more of the same: tiny waves, short periods, and messy conditions.

Even when we get a glassy morning on Monday September 7th – with the wind dropping to 5 km/h from the southwest and the water going flat – the swell is only 1 ft from the southeast. That’s not enough to break cleanly. The rest of the first week and into the second is all 1 ft to 2 ft slop, with poor energy readings (mostly under 40) and onshore winds.

We do see a small lift around Thursday September 10th, with the swell pushing to 3 ft from the south-southeast. The combined energy climbs to 39 on Thursday afternoon and even 42 on Friday morning – the highest of the whole run. But that’s still weak, and with moderate cross-onshore winds at 20-25 km/h, it’s choppy and a mess. For a spot like Octagon House, which is exposed to the southeast and fairly consistent, this is a real dry spell.

Bottom line: There’s nothing surfable in this 16-day window. The swell never reaches a size that matters, and even the best winds can’t fix tiny, gutless waves. If you’re desperate, the Thursday/Friday of the second week (10th-11th September) has the most energy at 39-42, but it’s still poor. I’d say sit this one out, mate. The forecasts can change, but right now it’s a blank run.

Rusty.
