The Lowdown
Alright, Rusty here again, switching to feet and Fahrenheit.
Let’s cut to the chase. Octagon is in a rough patch. The water’s warm, about 87°F, which is a bit warmer than usual for this time of year. It’s muggy.
Starting Thursday, July 30th, don’t bother. Tiny 2ft south swell with a 5-second period, cross-shore winds, and weak energy around 21. It’s a mess.
Friday, July 31st is the same story – 2ft south swell, 5 seconds, moderate cross-shore. Energy is a pathetic 17. Leave the board in the car.
Saturday, August 1st morning gives you a slight tease. The swell stays at about 2ft from the south, but the wind goes cross-offshore from the southwest, cleaning it right up. The wave state is clean. But the period is only 4 seconds, and the energy is just 36. It’s a beginner-friendly ankle-slapper on a foamie. The afternoon gets all chopped up.
Sunday, August 2nd morning is your best shot. The swell bumps to 3ft from the SSW, and the wind swings cross-offshore from the west again, giving you clean, glassy conditions. The energy climbs to 81. It’s still small, but it’s the cleanest window of the whole forecast. Watch out for thunderstorms in the area.
Monday, August 3rd morning is another clean one with a 3ft south swell and light offshore breeze. Period hits 6 seconds, energy at 72. The conditions are clean enough for a longboard session, even if it’s not big.
From Tuesday, August 4th all the way through Friday, August 14th, it’s a long, drawn-out stretch of weak, short-period junk. Swell heights bounce between 1ft and 4ft, but the period is almost always 4 to 6 seconds. Most of the time the wind is cross-onshore or onshore. The combined energy rarely breaks 100. There’s a quick spike on Tuesday morning the 4th with 4ft and 116 energy, but the wind is cross-onshore, so it’s not clean.
You get a few clean mornings in there, like Saturday, August 8th (3ft, light wind), but the swell has zero power. At the very end, Monday, August 10th afternoon shows a tiny 1ft swell but with a 10-second period. That’s a weird combination – low energy (34) and cross-onshore wind. Not worth it.
The only real standout is the early morning of Sunday, August 2nd. It’s not big, but it’s your cleanest option for a small wave. For a total beginner, Saturday, August 1st morning could work if you just want to get wet.
It’s a grim two weeks. The swell refuses to get its act together, and the wind is constantly wrecking what little there is. It’s a long stretch of nothing.

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.
