The Lowdown

Alright folks, Rusty here. Let’s have a look at what the ocean is serving up at this spot. Honestly, it’s a tough one. The next 16 days are mostly a write-off, with a couple of fleeting moments that might get your heart rate up. We’re looking at a long stretch of small, messy, or non-existent surf.

For the first week, the story is all about pain. From now right through until the 8th of September, it’s a grim run. The wind is constantly onshore or cross-shore, keeping everything lumpy and chopped out. Swell energy is weak to moderate, with values mostly below 100 and rarely hitting 200. That combined energy reading of 504 on the 1st of September morning looks promising at first glance, but it’s a short-period windswell packing only 6 ft from the northwest, and with a stiff 19 mph crosswind, it’s a complete mess. Not worth paddling out.

Things stay in the “poor” category right into the middle of the month. There’s a small window on the 6th of September that gets a score of 1 out of 10. It’s marginal, with 4 ft swell from the NW (period 9 seconds) and light cross-onshore wind, but the energy is moderate (201). Still, it’s not appealing.

The first real glimmer of hope shows up on the 14th of September, a Monday morning. We get a clean, cross-off breeze from the SSE at 9 mph and a pulse of 3 ft swell from the NNW. It’s a short 6-second period, so it’s not going to be holding up with any power, but the conditions are clean. You could get a few crumbly ones. Combined energy is a moderate 114.

The standout window in this whole outlook is the morning of the 15th of September. This is your best bet by a long shot. We get 4 ft of NW swell with a moderate combined energy of 344. The wind is NNE at 9 mph, blowing cross-offshore, keeping the face clean. The period is 9 seconds, so it’s a bit of a short-period windswell, but the conditions are “expect good surf conditions.” For this spot, that’s as good as it gets in this forecast. It’s the one morning to circle on the calendar.

The afternoon of the 15th sees the wind swing back to the NW and pick up, ruining it.

After that, the 16th of September morning sees 4 ft of WNW swell (period 10 seconds) with moderate energy (279), but the wind is cross-shore from the north at 12 mph, putting a chop on it.

So, the verdict is grim. A long dry spell with only a small, clean window on the 15th of September morning. If you’re desperate, there’s a sliver of hope on the 14th morning. Don't expect much. The rest of this is for the windsurfers or a quiet beach walk.

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.
