The Lowdown
Alright folks, Rusty here. Let’s get straight into it. The next 16 days out at Octagon House (exposed to SE) are looking pretty flat, to be honest. There’s just no real energy on the table to get excited about, and I’m calling it as I see it – we’ve got a long stretch of poor surf conditions ahead.
Right now, on Monday morning the 20th of July, we’ve got a tiny 1 ft swell from the SSW with a period of just 4 seconds. The combined energy is a weak 7, so basically nothing. The water temp is sitting at 86°F, which is about average for this time of year with a 1°F anomaly, so it’s nice and warm. Winds are light from the W at 3 mph, cross-off, so the surface is clean, but with that little bump, it’s not worth paddling out for. It’s a poor surf situation, and that’s the story for the whole day.
Tuesday the 21st isn’t any better. We’re looking at 1 ft from the SSW, period still 4 seconds, and combined energy barely hitting 10. The morning is clean with a cross-off wind from the west, but the swell just isn’t there. By afternoon, it gets cross-on and choppy. Honestly, this is tough.
The rest of the week into the weekend and beyond doesn’t improve. Wednesday the 22nd morning sees a slight bump up to 3 ft from the SW, period at 5 seconds. Energy climbing to 57. Still, the model says “poor surf conditions.” Winds are cross-off from the WNW at 12 mph, so it’s clean, but the swell is too weak and short-period to form anything rideable. It’s going to be a lot of small, mushy, close-out slop if you even try.
From Thursday the 23rd all the way through to Tuesday the 4th of August, we are stuck in a rut. Swell heights bounce between 1 ft and 3 ft, with periods mostly 4 to 5 seconds. The combined energy rarely breaks 50, and the predominant wind is from the S or SSW, cross-on, at 9-16 mph, making it choppy and messy. Every single entry is marked “poor surf conditions.” There’s no standout, no window of goodness, no sneaky groundswell pulse.
For a beginner spot like Octagon House, this is a total wipeout. The break is “fairly consistent” normally, but a run like this – two solid weeks of nothing – is a real drought. The only positive I can give you is that the water is warm, so if you want to float around on a board, it’s fine. But if you’re looking for a wave, you’re looking in the wrong place. This setup is more interesting for a kite than a paddle right now.
We’ll keep an eye on it, but forecasts can change. For now, it’s a no-go. Rusty out.

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.
