The Lowdown

Right then fer me mateys who ain't got a lick of swell. Gonna be a tough stretch ahead, so let's get into it.

Look, I'm gonna be straight with ya – this forecast is a proper desert for a good long while. We're looking at a gap of nearly two weeks with absolutely nothing worth paddling out for. From now right through 'til the 22nd of August, it's all poor surf conditions with cross-shore and onshore winds messing up what little bump there is. The swell is small, the wind is rubbish, and the energy is just not there. The combined energy of all swells directed here barely cracks 300 (309) on the 15th morning, but it's still a lumpy, cross-shore mess. You'd be better off going for a run.

The saving grace, and I mean the *only* saving grace, looks like it's gonna be that Monday morning, the 24th of August. Now, that's a long way off, so don't bet the farm on it, but it's the only light in the tunnel. The wind is forecast to be glassy, dead calm, which is a huge positive for clean surf. We'll have a 4ft swell rolling in from the WNW, and the combined energy is a solid 513. That's proper wave energy. The water temp is around 69°, which is pretty normal for this time of year, so no need for a thick steamer.

But here's the catch. The swell period is a touch over 13 seconds, which is nice and long, but the break is a reef. That long-period groundswell on a reef can mean it breaks a bit too straight, and with the swell size being moderate, it's not a beginner's wave. It's a spot for the advanced crew, and you'll likely have company, as it's a spot that's often crowded.

So, keep your eyes on that Monday the 24th, lads. That's your best bet, but it's a long way out. The rest of the run is a write-off.

Rusty.

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.
