The Lowdown
Alright folks, Rusty here. Let's talk about what's on the menu for our local reef break.
First off, I gotta be straight with you, the next week and a half is looking pretty tough. We've got a real dry spell kicking off. From Monday the 24th of August all the way through to Sunday the 6th of September, it's a write-off. There's no good surf to be had, with strong winds and messy conditions messing things up every single day. That’s nearly two weeks of nothing. It’s one of those stretches where you’d be better off doing something else.
Now, hang in there, because things start to look interesting come Monday the 7th of September. The morning is still only marginal, with a 3ft swell coming from the WNW at a period of 10 seconds. There’s a light cross-shore breeze, so it’s not great, but you can see the potential. The combined energy is still low (266), so the ocean is just waking up.
But Tuesday the 8th of September… that’s the real standout. Morning is where it’s at. We’ll see a solid 6ft swell, direction from the WNW, and the period jumps right up to a very long 15 seconds. That’s proper groundswell energy – it’ll have some real push. The water temp here is sitting about 66°F, which is a bit colder than normal for this time of year. The best news? The wind is glassy. Zero, zip, nothing. That’s going to be some seriously clean surf. The combined swell energy is a strong 1594, so there’s plenty of power in the water. Just keep in mind that with a long period like that at a reef break like this, the waves might wrap in a bit more evenly and organized. The sets will be less frequent but more defined.
That Tuesday afternoon gets a bit messy as the wind swings onshore, but that window of glassy morning is the one to circle on your calendar. It’s the best we’ve got in this 16-day outlook, and it looks promising.
The swell direction is a touch west of the recommended optimum SW, but when you’ve got 15-second groundswell and glass, you take it and don’t complain.
Stay patient, that Tuesday the 8th is your day.

Information about the Reef Surf forecast
The above surf forecast table for Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Reef can be found by selecting the local surf guide option on the grey menu. Our Reef 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 (Reef) 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 Reef 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.
