The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for the coming weeks.
Honestly, mate, it’s a rough start. We’re looking at a solid two-week stretch of almost nothing worth paddling out for. The first bit of real hope doesn't show up until Saturday, August 1st, and even that is a brief window.
The main issue is the wind. For the first week, it's locked in from the NW and NNW, blowing cross or cross-onshore, and it's choppy as hell. The swell is tiny and weak for days on end. There's a little bump in energy on July 25th, with combined swell energy hitting 280 (moderate), but the swell is short-period windswell at 5ft and the cross-onshore wind just ruins it. It’s a mess.
The only standout, and I mean the only one worth mentioning, is the morning of Saturday, August 1st. We get a glassy window at Reef, with a slight air and the wind dropping to nearly nothing. The swell is a clean 4ft from the W with a 9-second period, and the combined energy is a solid 241 (moderate). It’s not a monster, but after all that chop, glassy conditions make it the best on offer. The water is a touch warmer than normal for this time of year, sitting at 70°.
After that little window, it gets messy again. The wind swings back to the north and the conditions get lumpy and cross-shore. There’s a late pulse of longer-period swell around August 5th, with the period hitting 11 seconds and the energy jumping to 582 (moderate to strong), but the wind is cross-onshore again, turning what could be a good groundswell into a choppy mess. The morning of August 8th has a glimmer of hope with a light breeze and a 4ft swell, but the cross-onshore wind is still there, making it marginal at best.
For a reef break like this, which is fairly consistent and exposed to the SW, the longer-period swells that show up later in the window would be a dream if the wind co-operated, but it just doesn't. Honestly, if you're not keen on dodging chop, the kite gear might be the better option for most of this period.
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.
