The Lowdown
Alright, I'm gonna level with you. For the Reef, this 16-day forecast is a game of waiting. The first week is a drought—6 straight days from Monday the 7th through Saturday the 12th with essentially zero surf on the menu. It's gonna be flat and frustrating.
The first time you might want to wet a line is Sunday morning, September 13th. There's a 4ft swell coming from the NW with a long 13-second period, and total energy sitting at 461—that's moderate. Winds are light and cross-shore, so it'll be clean enough. The comment says it's "marginal," so don't expect magic, but it's something.
The real highlight is Monday morning, September 14th. This is it. A 5ft swell out of the NW, 12-second period, and energy hitting 685. Winds are light out of the north, just cross-shore, which means near-glassy conditions on the face. For an exposed reef, that's gold. Water temp is 68°, which is normal for this time of year, so no need to dig out the thick suit. This wave is advanced only—5ft on reef can get heavy. Crowds are likely, so paddle out early if you want it to yourself.
Beyond that, the swell backs off fast. Tuesday the 15th is small, and the rest of the second week is mostly weak and wind-affected. There's a pulse on Monday, September 21st with a 4ft NW swell and 503 energy, but a fresh 19 mph cross-shore wind will chop it up. Not worth the hassle.
Make the call for the 14th. It's the cleanest window in a long, flat spell.

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.
