The Lowdown

Alright, this is Rusty. Let's talk about what's on the menu for the next couple of weeks.

Honestly, it’s a tough stretch. We’re looking at a long, dry spell of poor conditions before anything remotely worth paddling out for shows up. The opening days are a write-off, with small, weak swell and onshore or cross-shore winds messing everything up. The first sniff of something half-decent doesn't come until Tuesday the 15th, but even then, it’s a one-morning window.

The best of the entire period, and the only thing that really gets me excited, is the morning of Tuesday the 15th. The Reef is looking at a clean 4ft swell from the NW with a period of 11 seconds, and the wind is forecast to be glassy. That’s a rare combo. The combined energy is moderate (486), so there’ll be some push. This is the clear standout – get on it if you can. The afternoon of the same day gets messy with a strong cross-onshore wind.

The only other potential is the morning of Sunday the 13th. The Reef sees a bigger 5ft NW swell (13-second period, 841 energy), but it's a cross-off wind. It’s not perfect, but it’s a step up from the rest of the garbage. Just be aware, that size might be a bit much for the beginners, and the period is long enough that those waves might be a bit straight at the beach but should work nicely on the reef. The afternoon blows out again.

Before that, there’s a solid 10-day stretch from the 2nd to the 12th with absolutely nothing worth recommending. The swell is tiny, the wind is poor, and the quality is just not there. A few mornings in the second week show a brief window of clean surf, like Saturday the 12th morning, but the swell is so small (2ft) it’s barely a ripple.

The water is sitting around 69°, which is bang on average for the time of year, so nothing weird there.

So, to sum it up: the 16-day window is a drought. Your only real shot is the glassy morning of Tuesday the 15th. Set the alarm, and don't be late.

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.
