The Lowdown

G’day, it’s Rusty here.

Alright, let’s cut to the chase. This next stretch of days is looking pretty grim for a proper surf. The only spot on the map is Reef, and she’s not giving us much to work with. The water’s sitting right at a normal 68°F, so no surprises there.

The whole run kicks off with a poor excuse for surf. This Sunday and Monday, the 9th and 10th, the swell is small—2 to 3 feet from the west-northwest—and it’s short-period stuff. The energy is weak (under 100), and the wind is coming across and onshore from the north-northwest. It’s a choppy, gutless mess.

Mid-week, around the 12th and 13th, the energy picks up a bit, reaching into the moderate range (159 to 283), and the period stretches out to 10-11 seconds. The size stays around 3 feet. But the wind is still cross-shore, fresh at times, and the surface is going to be lumpy. It’s a step up in power, but the wind is going to kill any chance of a clean wave.

Friday the 14th is more of the same—3 feet but with a fresh 19-22 mph cross-shore wind. Then it all falls apart on the 15th and 16th. The swell drops to almost nothing, just a tiny 0.3-foot pulse from the southwest, and the wind gets strong, 22-25 mph. There’s nothing to ride. It’s flat.

The following week stays weak. From the 17th onward, we’re seeing tiny 0.3 to 2-foot swells from the southwest and west-northwest. There’s a brief moment on the morning of the 19th where the wind goes offshore and it cleans up, but the swell is still only 0.6 feet. You’d be better off with a paddleboard. The energy numbers are tiny, mostly in the single digits and teens.

Towards the end of the run, on the 23rd and 24th, we see a bit more size. Sunday the 23rd brings 3 to 5 feet, but it’s short-period, sloppy swell from the north-northwest, and the wind is still cross and cross-on. It’s going to be a blown-out mess, though the energy does get to 124. The morning of the 24th looks like the pick of the bunch—a gentle cross-shore, 3 feet of swell from the northwest with a longer 11-second period and energy at 144. That’s the one window I’d keep an eye on. The afternoon adds a bit more size, around 4 feet, but brings a cross-on breeze and chop with it.

Honestly, this is a tough two weeks. The spot is fairly consistent, but the wind and the swell aren’t lining up. We might see a change, but right now, the 24th is your best chance, and even that’s not a sure thing.

Keep the board in the car and wait for a better day.

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.
