Alright, Rusty here. Let’s talk about what’s on offer for the next couple of weeks.
Honestly, it’s a bit of a flat spell to start. We’ve got nothing really worth paddling out for for quite a while. The first ten days or so are a write-off – the swell is tiny, the wind is mostly onshore or cross-onshore, and the surf conditions are just poor. You’re looking at small, weak 1ft to 2ft windswell from the SSE and SE, with periods hanging around 4 to 6 seconds. Not enough push, and the wind messes up what little there is. The water temperature is 87° at the start, which is a touch warmer than normal for this time of year.
It isn’t until Monday, July 20th that we see a glimmer of hope. That morning, at Octagon House, we get a bit of a lift: a 3ft SSW swell with a period of 5 seconds, and the wind goes light and clean. The combined energy is only moderate, sitting at (55), but finally we get some clean conditions to go with it. It’s not epic, but it’s surfable. The next morning, Tuesday, July 21st, is actually the standout of the whole outlook. Right on the morning of the 21st, we get a 3ft SSW swell with a 5-second period, and the wind goes glassy. That’s a rare treat here. The combined energy is (50), so still moderate, but with glassy conditions, it’ll be clean and fun for a beginner-friendly wave. The crowd factor at Octagon House is listed as “sometimes,” so you might have a few others out, but nothing crazy.
After that, we get a few more mornings with clean conditions and small 3ft S and SW swells, but the energy stays moderate, and the afternoon winds always swing onshore. Nothing else really stands out as a must-surf session. It’s a pretty lean run overall, but that Tuesday morning on the 21st is the one to aim for if you can get out there.
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.
