The Lowdown
Alright, Rusty here, looking at the Reef.
Honestly, mate, it’s a bit of a rough patch. We’re staring down a long stretch of nothing much. From Saturday the 5th all the way through to Monday the 14th, it’s mostly poor surf. The wind is constantly buggering things up – cross or cross-onshore, often blowing a solid 15 to 30 km/h, and the swell is just not making the most of it. There’s a bigger pulse of energy on Monday the 7th, with a 6ft swell coming from the WNW, but it’s being smashed by a 30 km/h cross wind. That’s a kite-surfing day, not a paddle one.
The only real beacon in the dark is Tuesday the 15th, early. We’ve got a clean 5ft NW swell running with a 9-second period. The wind flips light offshore from the ESE at just 5 km/h. That’s glassy, clean, and lined up. The energy is moderate (462), so it’s got some grunt. For an advanced reef, this is the best offer by a mile.
After that, it’s back to the struggle. The 16th and 17th have some marginal moments, but the wind turns onshore again. The 19th of September (Saturday) morning has a shot at the same kind of glassy conditions with a 4ft NW swell, but it’s a long way off, so we’ll keep an eye on it.
Water temp is sitting around 68°F, which is about average for the time of year, so the wetsuit will be fine.
Bottom line: the first 10 days are a waste. The one and only standout is Tuesday the 15th morning. Be there or be square.

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.
