The Lowdown
Gather 'round, crew. Rusty here. Let's be straight with you – the outlook for Octagon House for the next couple of weeks is pretty grim. We've got a long stretch of flat, weak, and choppy conditions ahead with no real surf to speak of. The first surfable recommendation doesn't kick in until the very end of the period, and even then, it's marginal. We're looking at a blank run that stretches from now, Saturday the 12th, all the way through to the end of the month.
The main issue is a total lack of energy. For days on end, the combined swell energy sits in the weak zone, with readings mostly between 4 and 99. That's barely a ripple, let alone a wave. Winds are almost constantly cross-onshore or onshore, adding chop and ruining what little shape there might be. It's a write-off for paddle surfing.
Now, the water temperature at Octagon House is sitting at 87°F, which is a touch warmer than normal for this time of year. Nice for a swim, but doesn't help the surf.
If we look right to the end of the forecast, there are a couple of tiny glimmers. On the morning of Friday the 25th of September, we see a little 3 ft swell from the East with a short period of 4 seconds. The combined energy is still weak at 26, but the wind swings to a light cross-offshore from the NNE, giving us clean conditions. Then, on the morning of Saturday the 26th, we get a similar setup: 3 ft from the ESE, period of 5 seconds, combined energy of 42, and again a light cross-offshore from the NNW making things clean. Finally, on the morning of Sunday the 27th, the wind turns offshore from the NW at 9 mph, giving us a gentle offshore and clean surf with a 2 ft swell from the ESE. These are the only windows where the surface looks surfable, but the swell is tiny and weak. For a beginner spot, these clean, small waves could be alright for a longboard, but don't expect any power. Given how flat it's been, it's hard to get excited, but at least the wind is right.
To be honest, with such weak swell and poor surf quality for so long, this stretch is looking more like a kiteboarding window than a paddler's paradise. There just isn't the push for a proper surf.
For now, keep the boards in the rack. It's a tough run, but it won't last forever.
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.
