The Lowdown

G’day, Rusty here. Look, we’ve got a bit of a mixed bag coming up over the next couple of weeks. The surf kicks off with some small, clean windows, but the real standout is a nice pulse of swell later in the first week. Let’s get into it.

We start off Monday 24 August with a tiny, marginal 3ft south swell at 10 seconds and a light north cross-breeze – not much to get excited about, energy is a weak 275. Water temp is sitting at 63°, which is about average for this time of year, so no wetsuit drama there. By Tuesday 25 August, things pick up a notch. The morning sees a 5ft north-east swell, but it’s short period at 7 seconds, so a bit fat and sectiony. Wind is a moderate north cross-off, making it clean, and the energy jumps to 390 – moderate. The afternoon gets even better: 5ft north-east swell, period dropping slightly to 8 seconds, but wind stays clean from the north-northwest as a gentle breeze, and the energy is 278. This is a solid, fun session for the advanced crew at Long Reef – a reef break that’s fairly consistent. Crowds are sometimes a factor, so keep an eye out.

Wednesday 26 August morning is another cleanie with a 4ft east-north-east swell at 8 seconds, cross-off wind from the south-southwest, and energy at 204. It’s a good option, but the afternoon turns ugly with a 6ft south swell and short 6-second period, plus a moderate south cross-shore – choppy and messy, more of a kite session than a paddle.

Now, the real standout is Friday 28 August morning. Glassy conditions, 4ft south swell at 10 seconds, energy a solid 333. That’s a groundswell, and for a reef like Long Reef, the longer period means better shape and more grunt. The wind is glassy, so it’ll be clean as a whistle. This is the best wave in the window – consistent, decent size, and offshore flow. Saturday 29 August morning is also a ripper: 4ft south-south-east swell at 10 seconds, cross-off breeze from the south-southwest, and energy at 275. Clean, lined up, and a pleasure to surf.

After that, the surf drops off quickly. Sunday 30 August morning is still surfable but small at 3ft, and then we hit a long dry spell. From Monday 31 August right through to Sunday 6 September, the swell is tiny – mostly 1ft to 2ft – and the energy is weak, often under 100. A few mornings have glassy or offshore winds, but there’s just not enough wave to ride. The run of poor conditions stretches for over a week, which is a bummer, but it’s not unusual for this area. The last chance for a sniff comes on Monday 7 September morning with a 2ft south swell and offshore wind, but it’s still very small.

The long-range standout is Tuesday 8 September morning: a 4ft north-east swell at 7 seconds, offshore wind from the west, and energy of 162. It’s a week and a half away, so less certain, but if it holds, it’ll be clean and rideable for the advanced crew.

Best bet: Friday 28 August morning – glassy, 4ft south groundswell, pure magic at Long Reef.

Rusty.

Information about the Long Reef Surf forecast

The above surf forecast table for Long Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Long Reef can be found by selecting the local surf guide option on the grey menu. Our Long 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 (Long 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 Long 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.
