The Lowdown
Alright folks, Rusty here. Let's have a look at what's comin' down the pipeline.
To be straight with you, this 16-day window is a tough one. We're looking at a long stretch of flat, choppy, or just plain messy conditions for our local reef. The first swell of any real note doesn't show up until Tuesday the 11th, and even then it's got some issues. For the first ten days, you're looking at a whole lot of nothing. The wave energy is consistently weak (often in the double digits, like 73, 60, or even 31), with a lot of cross-onshore wind and short, weak periods.
Water temp is sittin' right around 68°F normally for this time of year, so nothing weird there.
The only time we see something worth gettin' wet for starts on the morning of Tuesday the 12th. The swell backs off the cross-onshore a touch with a light breeze, and we get a 4ft swell from the WNW with long-period energy at 10 seconds. The combined energy jumps up to a solid 242 (moderate), and it's the only day that even rates a "marginal" call. It's still a cross-onshore wind from the NNW, so it won't be glassy, but the size and period could offer a few workable runners for the advanced crew out at Reef (Reef). It's a fairly consistent spot, exposed to that SW optimum, but this WNW swell will still wrap in.
Later in the week, look at Thursday the 13th and Friday the 14th. The wind goes cross-shore, which is a step up, and we see 3ft to 5ft of swell, but the period tanks to a short 6 to 8 seconds combined with fresh breezes over 15 mph. The energy gets a bit more grunty (up to 193 on the 6th), but that's because of the wind creating chop, not clean swell. That setup looks more interesting for kite surfing than paddle surfing, honestly.
So, call it: if you absolutely have to get out, the morning of Tuesday August 12 is your best bet. After that, it gets sloppy again with the wind cranking up to over 18 mph and dropping back to flat by the 15th. A long wait for a short window.
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.
