The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the table for the next couple of weeks.

We've got a long stretch of quiet, frustrating conditions ahead. The better news is that the water is sitting at a warm 87°F – a touch warmer than normal for this time of year, so at least you won't be freezing while you're waiting for something to happen.

The whole 16-day window is a bit of a struggle. The only spot on the radar is Octagon House, an exposed beginner-friendly break that's fairly consistent. The problem is, the swell just isn't showing up. For the first week, we're looking at tiny, weak waves. The combined wave energy is barely registering, with values like 12 and 23 (very weak). The swell direction is mainly from the SSE to S, with short periods around 4-9 seconds, so it's just windswell without any push. Winds are mostly cross or cross-onshore, which keeps things messy and choppy.

There's a little glimmer of hope on the morning of Saturday, August 22nd. The wind swings to a light WSW cross-offshore, giving us clean conditions. The swell is a tiny 2ft from the SSW, but the energy is still very low at 36. It's surfable for a beginner on a foamie, but it's not going to get the heart racing. The next morning, Sunday the 23rd, is similar with clean conditions and a 2ft SSW swell, but again, the energy is weak.

We hit a bit of a dry spell right through the end of August and into the start of September. The mornings of the 24th, 25th, and 31st of August all have clean cross-offshore winds, but the swell sizes are tiny (2ft to 3ft) and the energy is still very weak. The 25th has a slightly better 3ft swell, but the afternoon gets blown out by a fresh 19 mph cross-offshore wind.

The best bet I can see in this whole outlook is the morning of Saturday, August 22nd. It's the only day where the wind is light and offshore, giving you the cleanest surface. The 2ft, 5-second swell from the SSW is small, but it's rideable for a longboard or a funboard. The crowd factor is listed as "sometimes", so you might have the place to yourself if you're early. It's not a standout by any means, but it's the pick of a very poor litter.

Later in the window, on Wednesday morning, September 2nd, we see a glassy morning with a 2ft SSE swell. The energy is still weak (21), but the glassy conditions make it worthwhile for a beginner to get a few clean, small waves. Don't expect anything powerful.

The rest of the days are dominated by stronger onshore winds and choppy conditions, or just no swell at all. For the first week, it's a lot of waiting. For a beginner-friendly break like Octagon House, this is a tough run. If you're a kiter, these onshore winds and small, messy waves might offer some fun, but for a paddle surfer, it's a quiet period. The forecast could change, but right now, keep your expectations low.

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.
