The Lowdown

Alright, Rusty here. Let’s take a look at this local stretch. We’ve got a pretty long run of flat or nearly flat conditions ahead, so don’t go getting your hopes up for a quick fix.

Right off the bat, the whole 16-day window is a frustrating one. The first surfable recommendation doesn’t come until Friday afternoon, the 31st of July, and even then it’s a dud. The waves at Octagon House are tiny, coming in at just 2ft from the south with a short, weak period of 5 seconds. The combined swell energy is a paltry 17, so there’s basically no power in the water. The wind is a moderate cross-onshore, so it’s choppy and messy. The water temp is 87°, which is a touch warmer than normal for this time of year, but that’s about the only thing that’s slightly interesting. This is poor surf, pure and simple.

We then roll through the rest of the weekend and into the first week of August with nothing but zero scores. Saturday the 1st has a slightly cleaner morning with a cross-off breeze, but the swell is still a pathetic 2ft at 5 seconds and 23 energy. Sunday morning the 2nd looks clean again with a gentle cross-off, but the swell is still 2ft with 30 energy. Monday morning the 3rd is clean but tiny at 2ft. The pattern is the same: tiny, weak south swells, usually with a crummy onshore wind or a clean but powerless morning. There’s a gap of solid days here with no real surf – just a long, drawn-out stretch of nothing.

Into the second week, from the 4th of August onwards, it’s still the same story. The swell height barely ever gets above 2ft, the period is always short (4-6 seconds), and the combined energy never cracks 40. Most afternoons are a write-off with a fresh cross-onshore breeze. The morning of the 7th has a little more period at 6 seconds and 28 energy, but it’s still tiny and cross-on. The 11th of August afternoon shows a slight bump to 40 energy, but the swell is still 2ft with a short period and a moderate cross-onshore. It’s all just paddling practice at best.

Honestly, there’s no standout, no hidden gem, no reason to get excited. The best you could hope for is one of the cleaner mornings, like the 2nd or 3rd of August, but even then, you’re looking at knee-high slop. For a beginner, it’s safe, but for anyone else? It’s a waste of wax. The setup is so weak and wind-affected that it looks more interesting for kite surfing than paddle surfing on those afternoons with a decent breeze.

The forecast is reliable for the near term, and it’s grim. There’s nothing promising on the horizon. It’s a flat spell.

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.
