The Lowdown
G’day, I’m Rusty. Let’s break down what’s cooking at this reef over the next couple of weeks.
To be straight with you, it’s a total drought. The whole 16-day window is a washout – no real swell, no decent waves, just a long stretch of flat or nearly flat conditions. From the start on Saturday the 15th right through to the end of the month, there’s nothing worth wetting a line for. There’s a big gap of poor surf that runs all the way until the final few days. The only tiny pulse comes on Sunday the 30th, with a weak, short-period NNW windswell around 4ft to 4ft, but with a period of just 6 seconds and combined energy only hitting 91 to 100 (moderate energy), it’s chopped up by cross-shore winds. That’s more of a kite day than a paddle session.
A few mornings – like Sunday the 16th, Monday the 17th, and Wednesday the 19th – are glassy, but the swell is tiny, barely ankle-high at 0.3ft. Water temp sits at 68°, just 1° cooler than average, so it’s about normal for the season. But none of that helps when there’s nothing to ride. The reef stays open to SW swells and that’s the best direction, but even when a little 1ft groundswell with a long 14-second period and 45 combined energy shows up on Tuesday the 18th, the wind is cross-onshore or onshore, keeping it bumpy.
Plainly, there are no good surf options in this 16-day window. This reef is not a consistent spot, and a run like this is pretty normal for the area. Forecasts shift, but for now, leave the gear at home.

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.
