The Lowdown

Alright folks, Rusty here. Gotta be straight with you – this 16-day window for the Reef is a tough one. We’ve got a real flat spell on the horizon, with barely a ripple worth paddling for. The first few days are a write-off. From Saturday the 8th right through to the end of the second week, the score is a big fat zero. There’s no real surf on offer, just small, choppy, cross-shore junk. The combined wave energy is weak, often sitting below 100 (like 37 on Saturday afternoon), barely tickling the reef.

The water temp is sitting at 21°, which is pretty much bang on average for this time of year, nothing unusual there.

Now, if you’re desperate, there’s a tiny flicker of hope late in the period. On Thursday morning the 21st of August, we might see a tiny pulse of 0.5m swell from the NW, with a period of 11 seconds. The wind will be light cross-onshore from the WSW at just 5 km/h, which is about as good as it gets for this stretch. The combined energy is still weak at 81. It’s not a standout by any stretch, but it’s the closest thing to a surfable window. The break (Reef) is an exposed reef setup, so it needs a decent swell to work. This one is for the die-hards on a longboard.

Honestly, for most of the next two weeks, you’re looking at a blank run. The Reef is fairly consistent usually, so this is a poor run. Don’t hold your breath. The longer period swells (15-18 seconds) that pop up around the 16th-18th are tiny (0.1m to 0.2m) and from the SW, which isn’t the optimum direction (SW is optimum, but the size is laughable). It’s not worth suiting up for.

So, the only real option is that tiny window on the 21st. Even then, keep your expectations on the floor.

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.
