The Lowdown
G’day, it’s Rusty. Let’s have a look at the surf situation for Octagon House over the next couple of weeks.
Well, mate, I’ve got to be straight with you—this one’s a bit of a dud. Over the entire 16-day window, every single session is marked as “poor surf conditions.” There’s nothing that really stands out as a good option, and the swell stays tiny throughout. The highest combined energy we see is only 49 (on Monday 14th), which is weak. The longest run of almost nothing is from now right through to around the end of the first week. It’s a pretty bleak stretch for Octagon.
That said, the break itself is Octagon House. It’s a beginner-friendly, fairly consistent spot, exposed to swell from the southeast. It’s on the small side most days, with swell heights from 0.3 ft up to a max of about 3 ft (on Tuesday 15th and Wednesday 23rd). The swell direction is mostly south or southeast, which is okay for the break, with periods sitting between 4-8 seconds—mostly short-period, windswell stuff. There is a little bump of energy around the middle of the second week: on Tuesday 15th, the combined energy hits 44 with a 3 ft swell from the southeast, period 6 seconds, but the wind is onshore. The only time we get glassy conditions is on Wednesday 16th morning, with light ESE winds, but the swell is only about 2 ft from the southeast. It’s clean but tiny.
Because the swell barely cracks 3 ft for the whole run, it’s never too big for beginners—but it’s also never really surfable. The wind is a factor too: it’s cross-shore, cross-onshore, or onshore for almost every session, which won’t help the already poor quality. Water temps? On the first mention, it’s about average for the time of year.
Honestly, the only session that might be worth waking up for is Wednesday 16th morning if you’re desperate—glassy, 2 ft from the southeast—but it’s still a long way from good. The rest is a write-off. It’s the kind of run that’s more normal for a place that doesn’t get consistent swell, so don’t lose hope—forecasts can change.
