The Lowdown
Alright, Rusty here. Let's have a look at the forecast for the local reef setup.
Well, to be honest, it’s a bit of a tough stretch ahead. The water temp is sitting at 68°, which is pretty much bang on average for this time of year, so no surprises there. The problem is, for the next week or so, the wind is just relentless from the north, hammering the place with cross-shore chop and ruining what little swell there is. The swell energy is weak to moderate at best, but it doesn't matter because the conditions are just plain ugly. There’s a long gap here where there’s nothing worth paddling out for – from Sunday the 6th right through to Saturday the 12th, it’s all showing poor surf. You'd be wasting your time.
We finally see a slight glimmer on Sunday the 13th morning. A small clean window with a light NE breeze creating some cross-offshore flow, and a 3ft WNW swell at 9 seconds. It’s only surfable, not epic, with a combined energy of just 100. It’s a weak pulse, but at least you won’t be fighting the wind. Don’t expect much.
The next little bump comes around Monday the 21st. That Monday morning is the standout of the whole outlook. A cleaner setup with an ENE cross-offshore breeze at 9 mph should clean things up nicely. We’re looking at a 4ft NW swell with an 11-second period – that’s decent groundswell with a bit of push. Combined energy hits 463, so there’s some moderate grunt in the water. This will be the best chance to score something rideable. After that, the afternoon swings back to a cross-onshore, so get on it early.
Other than that, there’s not a lot to get excited about. A few other days show a bump in size, like the morning of Thursday the 17th with a 6ft NW swell (combined energy 600), but the north wind is howling at 22 mph, making it a lumpy, messy affair. That’s one for the experts only, and even then, it’ll be a battle.
So, to sum it up: if you want the best chance of a wave, pencil in Monday the 21st morning. Otherwise, it’s a waiting game.

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.
