The Lowdown
Alright folks, Rusty here. Let's have a look at what the next stretch has in store for us.
We're starting off with a real mixed bag. The first couple of days, 28th and 29th August, see some serious size coming in, but it's just too big and blown out for this spot. Then we hit a long, frustrating dry spell. From the 30th of August right through to the afternoon of the 5th of September, conditions are just poor. That’s practically a week of nothing worth paddling out for. The wind is mostly a messy cross-shore, and the swell is either tiny or completely wonky. The energy on the 30th of August morning is a weak (185), just to give you an idea.
But hold on, there is a proper light at the end of the tunnel. The real standout window looks to be the morning of Sunday, the 6th of September. We’ve got a solid pulse of swell arriving with glassy conditions. The wind is dead calm, which is about as good as it gets for clean waves. The swell will be a solid 5ft from the NW with a nice long period of 12 seconds – that's proper groundswell energy. The combined energy is a strong (652), so there's plenty of push behind it. Remember, that longer period means better shaped waves and more power, but also longer lulls between sets. It’s going to be a beautiful spot to be out there.
Before that, on Friday the 4th of September morning, there's a little pulse of very long period swell (16 seconds), but it’s only 1ft. It’ll be glassy, but you'd be hunting for the one set that comes through. A real waiting game.
The 12-second groundswell on Sunday the 6th is the one to circle on the calendar. It’s not huge, so it shouldn't be too daunting, but with that period and no wind, it’s our best bet by a long shot. Get on it.

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.
