The Lowdown
Alright, Rusty here. Let’s be straight with you. I’ve had a good look at the charts for the next sixteen days, and honestly, it’s a grim picture for the Reef. The wind is a problem from start to finish, and the swell just doesn’t line up right. You’re looking at a long stretch of basically nothing worth paddling out for.
The first real chance of anything rideable pops up almost a week away, on the morning of Monday, August 4th. Even then, it’s a struggle. We’ve got a 3ft swell from the WNW with a period of 9 seconds, and the combined energy is moderate at 126. But the wind is onshore, light, but still onshore. It’s pretty weak sauce. The water temperature is sitting right around normal for the time of year, so no surprises there.
The next few days after that are just more of the same – messy, lumpy cross-shore winds and small, weak swell. You’ll see some moderate energy spikes (139 on the 1st of August, 306 on the 9th of August), but the wind is just too strong and in the wrong direction to make anything of it. That 5ft swell on the 9th of August looks like the biggest push, but it’s wind swell with a short period of 8 seconds, and a fresh 19 mph cross-shore wind will chop it to pieces. That’s one for the kite crew, not for us.
The only real standout, if you can call it that, is the morning of Tuesday, August 12th. We’ll see a 3ft WNW swell at 9 seconds, with moderate energy (108). The wind is still cross-shore, but only a moderate breeze at 12 mph. It’s the best of a bad bunch, but it’s nothing to get excited about. The Reef is an advanced, exposed reef break that can handle a good SW swell, but we’re getting nothing from that direction.
Don’t bother with the second week. The pattern is locked in: strong, lumpy cross-shore winds and piddly little waves. It’s a blank run, and for this spot, that’s just how it goes sometimes. Forecasts can change, but right now, it’s a hard pass.
Stay patient,
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.
