The Lowdown

Alright, Rusty here. Let’s take a look at what’s cooking for the Reef over the next couple of weeks. It’s a real mixed bag, so let’s get into it.

We’ve got a solid pulse of energy coming in, but the timing and conditions are going to sort the men from the boys. The first real standout is Friday the 28th. We’re looking at a 8ft groundswell out of the WNW, with a nice long 11-second period. The real kicker is the wind – dead glassy in the morning from the north. That’s going to put the reef in prime shape, with some serious power behind it. The combined swell energy is strong, sitting at 1260. Be warned though, this swell is on the bigger side; the reef is an advanced spot, and this one’s gonna be packing some punch. Not one for the learners.

However, there’s a catch. The afternoon on that same day shifts: the wind swings NW and gets more cross-onshore, making things choppier and less appealing. You’ll want to be out there first thing for the best of it.

The rest of that first week into early September is looking a bit rough. Conditions get mixed up with cross-shore winds and the swell drops off fast. The super long-period (15-16 second) pulses from the SSW that roll in around the 1st and 2nd are weak – combined energy is only 22 to 24. Those are going to be tiny and hard to ride, more of a high-tide shuffle than a proper surf. That’s a few days of flatness there for you.

We get a tiny glimmer of hope on Saturday the 5th. A 3ft wave from the NW with a period of 11 seconds shows up, and the morning is glassy. It’s not going to be world-class, but at least it’s something to get wet on after a dry spell.

The water here is sitting at 67°, which feels a bit cooler than what we’d normally expect for this time of year – almost a degree off the mark. So you might want a spring suit.

Looking further ahead, the only other date that might get your attention is Wednesday the 9th. There’s a 3ft to 3ft WNW groundswell with a period of 12 seconds. The morning looks glassy again, and the combined energy hits 313. It’s not huge, but it’s clean. The Reef can handle that sort of size beautifully with clean conditions, so mark it in the calendar. Still, it’s a bit far out, so don’t plan your life around it just yet.

To sum it up: the clear winner is Friday the 28th morning. Get in the water early. After that, things go quiet until the 5th for a very average session, and the 9th might offer a clean but smaller option. Everything else in between is a write-off.

Stay stoked.

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.
