The Lowdown

Alright folks, Rusty here. Let's be straight with you – this 16-day window for Octagon House is a tough one. We're looking at a long, dry spell with barely a ripple worth paddling for. The first real chance of anything happens right at the very end of the run, but we'll get to that.

Right now, and for the next couple of weeks, it's mostly flat. The combined swell energy is extremely weak, often reading in the single digits to low double digits (30 or less). You'll see a lot of "poor surf conditions" in the logs, and that's the truth. The wind is frequently cross or cross-onshore, keeping things messy. There are a few windows of clean conditions early on the 20th and 22nd of July, with light offshore breezes, but the swell is barely there. On the 24th of July (Friday morning), we get a glassy session, but again, with a tiny 0.3 ft of swell, it's more of a paddle than a surf.

The pattern doesn't really change much until the very end of the month. From the 26th of July, we see a slight bump in size, but it's still under 3 ft, and the wind stays onshore, making it choppy and uninviting.

Now, here's the one thing that gets my blood pumping a little. Mark your calendars for the 31st of July and the 1st of August. We get a pulse of better energy. On the Friday afternoon (31st), the swell jumps to 4 ft from the SSE, with a period of 6 seconds, and the combined energy hits 126 – that's a moderate level. The following Saturday morning (1st August) it's holding at 4 ft from the SSE, period 7 seconds, and the energy is up to 178. The wind is light cross-shore, which is a big plus. The Saturday afternoon builds further to 5 ft from the SSE, with a period of 8 seconds and a solid 219 energy reading. This is the standout window. The swell direction lines up well with the optimum SE direction for Octagon House. It's a beginner-friendly break, so this size is perfect. However, keep in mind the winds are predicted to go cross-onshore in the afternoon, so the mornings will be the cleanest.

For the first week, honestly, don't bother. The second week is a slow build, but the real action is that last weekend in July / first of August. It's a promising lead, but it's far out, so keep an eye on it. The water temp is about average for the time of year.

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.
