The Lowdown
Alright, Rusty here again. Let’s talk surf for Octagon House over the next couple of weeks.
Honestly, it’s a bit of a drought. There’s a whole lot of flat, weak, and messy conditions headin’ our way, and the first real something worth paddlin’ out for doesn’t show until early September. Expect a long quiet run of tiny, choppy slop through the end of August.
The water temp is about 87°F right now, which is a touch warmer than normal for this time of year—no thick rubber needed.
From Tuesday 25th August through the end of the month, it’s pretty bleak. Tiny swells, mostly under 2ft, with short, weak periods and a lot of onshore or cross-onshore wind. The energy is barely registerin’—like 11 to 20 on the scale (weak wave energy). Thursday morning 27th looks clean with a light cross-off breeze, but with only 2ft of weak swell, it’s barely a ripple. Saturday morning 29th is glassy, but the swell is next to nothin’ at 0.3ft. Not worth the drive.
Then there’s a blank gap from Sunday 30th through Tuesday 1st September—more tiny, wind-affected slop with poor surf conditions. The energy stays weak (in the 5 to 17 range). You’d be better off takin’ a nap.
Wednesday 2nd September is more of the same: small SE windswell, onshore winds, and weak energy. It’s a rinse and repeat of 1ft to 2ft of swell, mostly onshore, with poor quality.
Now, there’s one mornin’ that stands out as the best on offer across the whole outlook. Wednesday morning 9th September brings a clean look to Octagon House. A light N/NE cross-off breeze, barely a breath, with some clean conditions. The swell is small though—only 2ft from the SE with a short period of 4 seconds (weak wave energy of 12). It’s not gonna be epic, but if you’re desperate, that’s your window for a clean, tiny wave. The break is exposed to SE swell and is fairly consistent, so it’ll be breakin’ even on these small pulses.
Before that, Thursday morning 3rd September has a cross-on breeze so the shape will be off. Later in the week, Friday 4th September afternoon sees a bump in energy to 37 (still weak), but with a fresh onshore breeze at 22 mph and only 2ft of swell, it’s just messy. Kite surfers might have more fun in that blow than we will.
So, overall: a long, dry spell with very little to get excited about. The only real standout is that clean Wednesday morning on 9th September—but keep your expectations low. The water’s warm, the waves are not.
Rusty.

Information about the Octagon House Surf forecast
The above surf forecast table for Octagon House provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Octagon House can be found by selecting the local surf guide option on the grey menu. Our Octagon House surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Octagon House) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Octagon House may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
