The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming our way.
Honestly, the next week and a half is a bit of a write-off for this spot. We’ve got a long stretch of poor conditions with only a tiny window of interest right at the end of the first week.
The water’s sitting at 20°, which is about normal for this time of year, so no surprises there.
The only real standout is Friday, August 28th. That morning, we’re looking at a clean 8ft swell from the NW, with a period of 12 seconds. That’s a proper groundswell and the energy is massive (1676). The wind is cross-shore, but it’s light enough that it should be clean. The problem is, this reef is going to be absolutely maxed out. At 8ft, this is strictly for experts only. The swell direction is from the NW, which is off the optimum SW direction for this break, so it might be a bit wonky, but for a spot that’s fairly consistent and exposed, it’s the only game in town that day. The afternoon is similar, just a touch less energy (1573) and a slightly shorter period of 11 seconds.
Before that, we have a few days of messy, onshore junk. Sunday the 24th looks properly ugly with strong cross-onshore winds and rain. Tuesday the 26th morning is the only other hint of something surfable, with a weak 4ft swell and glassy conditions, but the energy is low (159) and the period is short (7 seconds). It’s surfable, but very ordinary.
After Friday the 28th, the swell drops off a cliff. Saturday the 29th has no swell at all, and then we’re into a long run of tiny, weak, cross-shore crap with crowd levels that are likely to be high on the rare occasion something breaks. There’s a small pulse of 5ft on Monday the 31st, but with a period of 6 seconds and 22 mph winds, it’s not worth getting excited about.
So, to sum it up: if you’re an expert and you’ve got Friday the 28th free, that’s your one shot. Everything else is a waiting game.
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.
