The Lowdown
Alright, Rusty here, let's take a look at what's on the cards for this spot we're calling Reef.
To be straight with you, the next week and a half is a tough stretch. We're looking at a long, dry spell kicking off from July 25th. The swell is tiny, the wind is messy, and every session is a write-off until we get to the end of the month. It's one of those periods where you're better off doing the yard work or waxing a board that'll just sit in the car. The wait goes all the way through to Friday, July 31st, with nothing but small, choppy, and onshore junk before that.
Then, finally, things look like they're turning a corner. Friday morning, July 31st, is the first real sign of life. We've got a new WNW swell pushing in at 4ft with a period of 10 seconds, and the wind is glassy. The wave energy is moderate (249), but the morning is looking clean with light offshore flow. It's still a modest swell, but that glassy condition makes it the standout window in the forecast. It’s not big enough to be intimidating, but it’s the cleanest you’ll see it.
Saturday morning, August 1st, is the other one to circle. The swell bumps up a touch to 4ft from the WNW, still with a 10-second period, and the wind goes glassy again. The wave energy is getting stronger (321), and it should offer up a few more workable waves than Friday. For a low-tide reef setup like this, that longish period should help shape it up nicely.
The rest of the run into the second week looks average to poor. After that Saturday afternoon, the swell drops out again and the wind turns onshore or cross-shore, so we're back to small, bumpy conditions through to August 9th. The swell tries to push back up around August 5th and 6th, but it's short-period windswell from the NNW, and it's accompanied by onshore winds, so it’s messy. A beach break might be kite-surfing territory there, but for a paddle surfer, it's not worth the paddle out.
So in short: get your sessions locked in for Friday morning, July 31st and Saturday morning, August 1st. That's the best of the lot. The rest 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.
