The Lowdown
G’day, Rusty here. Look, I’ve gotta be straight with you – this stretch is a tough one. The whole 16-day window is a write-off for any decent surf. We’re stuck with tiny, weak slop the entire time, and the wind is almost never on our side. It’s a proper blank run, so don’t hold your breath.
Starting now and right through to the end of the month, there’s not a single session worth paddling out for. The only break on the radar is Reef (Reef) – an advanced, exposed reef setup that’s fairly consistent, but it’s not getting any love from the ocean. The swell is tiny, mostly hanging around 1ft to 2ft, with a few pulses barely reaching 3ft to 4ft on the 24th of July. Direction is all over the place from WNW to NNW, with periods all over the shop – short, weak 4 to 6 second stuff, and a few longer 10 to 13 second windows that just don’t have any size behind them. The energy is weak across the board, with combined swell energy readings mostly in the 20s to 90s (low), and only a couple of moments hitting 107 to 116 (moderate) – but even then, the wind ruins it.
The wind is the real killer. We’ve got a near-constant run of cross-on and cross winds from the NNW and NW, ranging from 9 mph up to a nasty 28 mph. That’s going to leave the surface chopped and messy. There’s a brief moment on the morning of the 30th of July with glassy conditions, but the swell is still a pathetic 2ft with low energy (45). Not worth it.
Water temp is sitting around 66°, which is about 1° cooler than average for this time of year – so nothing weird, just your standard cool water.
No standouts, no hidden gems, just a long stretch of poor surf. With the consistent onshore winds and tiny swell, this setup honestly looks more interesting for kite surfing than paddle surfing. We’ll keep an eye on the charts, but for now, leave the boards in the shed.
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.
