The Lowdown
Alright, Rusty here, let's talk about what's on the cards for the coming weeks.
Honestly, it's a pretty bleak run for the most part. We've got a solid 16-day window, but for the first 13 days, it's a total write-off. From Saturday the 29th of August right through to Thursday the 10th of September, the surf is just not happening. The energy is barely there, the wind is all over the place, and every session is tagged as poor. You're looking at a long stretch of flat, choppy, and lumpy conditions. It's that kind of period where you almost forget what a wave looks like.
The only flicker of hope comes right at the very end of the forecast. On Friday the 11th of September, we might just get a pulse of life. The morning session at Reef shows a 5 ft swell from the NW, with a combined energy of 719 – that's a solid, moderate push. The period is 9 seconds, so it's a standard wind swell, nothing too special, but it's something. The wind is a moderate cross-shore, so it's not going to be glassy, but it's surfable. The water temperature is sitting at 68°F, which is about normal for this time of year, so no surprises there.
The afternoon of the 11th drops off a bit, and by Saturday the 12th, we're back to the same old story. So, if you're desperate for a paddle, the Friday morning of the 11th is your one and only chance to get a few. It's a long-range call, so keep an eye on it, but don't hold your breath.
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.
