The Lowdown
Alright, Rusty here again, same deal, just switched to feet and Fahrenheit.
Let’s call this 16-day run what it is: a rough stretch at the Reef. Not much to get excited about. Cross-shore winds and onshore junk dominate. Huge gaps between any real surf. If you’re not a glutton for punishment, you’ll probably keep your board in the car.
We kick off August 30th with nothing but messy, wind-chop. The swell is tiny, the wind is 20–25 mph from the NNW hitting it sideways. That pattern holds through the first week. You’ll see a lot of moderate wave energy (crest factor in the 222 to 493 range), but with that 20–30 mph cross-breeze, the surface is just ugly.
Then on the morning of Friday, September 4th, finally a sliver of hope. Winds turn NNE at 15 mph, light offshore, the water goes clean. Swell runs about 2 ft from the NW with a long 13-second interval. That long period brings real shape and punch (combined energy of 205). This is the single best window of the whole forecast. If you have a flexible schedule, that morning is the one to chase. After that, it’s back to messy cross-shore junk for the rest of the day and all through the following week.
Water temp is 68°F, just about standard for this time of year—nothing unusual.
The second week gets even uglier. Extended dead periods. Winds howling at 35 mph by September 9th, lumping up tiny NW swell again. Rain showers roll in by September 13th with winds out of the WSW. The swell direction never matches up. Honestly, the only thing that might work is a kite, but for a proper surf session? Save your energy.
It’s a dry stretch. But this area turns around quick—forecasts change. Don’t give up just yet.
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.
