The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the line for this spot.
Alright, I gotta be straight with you – the next couple of weeks are looking pretty grim for this break. We’ve got a long stretch of nothing much to get excited about. The first real chance of anything halfway decent doesn’t roll in until Sunday the 23rd of August, and even then it’s a tricky one. Before that, we’re looking at tiny, weak swells with poor winds. Friday the 21st and Saturday the 22nd are write-offs. The wave energy is basically non-existent, with readings like 43 (weak) and 58 (weak), and the wind is all over the place – cross, cross-onshore, choppy. Just leave the board in the car.
Now, Sunday the 23rd. This is the only real standout in the whole 16-day window. We’ve got a solid 7ft swell rolling in from the W, with a period of 11 seconds. That’s a decent groundswell, packing some punch. The combined energy jumps right up to 1029 (moderate to strong). The wind is a clean cross-off from the SSE. That’s the good news. The bad news is the wave comment says it might be too big for this break. This is a reef break, so with that size and period, it could be a proper, heavy handful. It’s definitely an advanced-only kind of day. The water temp is sitting at 68°, which is about 1° below normal, so pretty average for this time of year. Sunday afternoon hangs in there at 5ft, but the wind shifts and the energy drops, so the morning is the call.
After that, it’s back to the doldrums. Monday the 24th is a complete mess with strong, cross-onshore winds and a massive, fat 10ft swell that’s just going to be blown out and closed out. The energy hits 1291 (strong), but with the wind howling from the WSW, it’s going to be a washing machine. The rest of the week into September is a sad story of tiny, weak swells, bad wind directions, and choppy conditions. There’s a little blip on the 30th of August with a 5ft swell from the NW, but it’s accompanied by a cross-onshore wind and the energy is still moderate. It’s not worth the paddle out.
In short, we’ve got one morning to look at – Sunday the 23rd of August. If you’re an experienced surfer and you’re comfortable with a solid, powerful reef break, that’s the time to be in the water. For everyone else, it’s a long wait for something better.
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.
