The Lowdown

G’day, Rusty here. Let’s be straight with you: the next couple of weeks are looking pretty flat and frustrating for surf. We’ve got a long stretch of tiny, weak waves and mostly cross-shore or onshore winds that’ll leave the surface chopped up. If you’re keen for a paddle, you’ll be doing it for the exercise, not the rides.

The only spot with any sort of pulse is Octagon House (Octagon). It’s a fairly consistent break, but it’s exposed and needs a decent swell to get going. For the first week, we’re looking at nothing but ankle-biters – swell heights hovering around 1ft to 3ft from the south-southwest, with periods of just 4 to 5 seconds. That’s pure windswell, no push, no shape. Add in the moderate cross-onshore breezes in the afternoons, and it’s going to be a messy, bumpy mess.

The mornings will be your best bet, just because the winds are lighter, but even then, we’re talking about marginal, knee-high slop. The water temp is 87°, which is a touch warmer than normal for this time of year, so you won’t need a wetsuit, but you might need a board you don’t mind dinging.

This flat spell runs right through the first week and into the start of the second. We’re looking at day after day of poor surf conditions with combined swell energy stuck in the weak range (values like 8, 9, 16 – nothing over 30). It’s a proper drought.

Now, there is a light at the end of the tunnel, but it’s a long way off. Around Sunday the 6th of September, things finally start to change. A swell arrives from the south, pushing the surf up to 5ft, and the period stretches out to 6-7 seconds. The combined energy jumps right up into the moderate range (233 and 225). That’s a real increase in power. But, and it’s a big but, the wind is still going to be cross-onshore from the south at around 12 mph, which will chop it up. It will be more powerful, but messy.

So, for this stretch, this is the only real highlight. It’s still not perfect, but it’s the biggest and most energetic swell on the board. Given the long flat run beforehand, it’s worth keeping an eye on, but don’t get your hopes up for a clean, glassy day. It looks like it’ll be more of a battle than a blessing.

Right, I’ll keep watching the charts. It tends not to stay poor for long around here, and a forecast can change in a heartbeat.

Catch you in the water.

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.

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.
