The Lowdown
Alright crew, Rusty here. Let’s talk surf for our local stretch. It’s a slow start, but there are a couple of days that’ll wake you up. Don’t rush it—the good stuff takes a few days to arrive.
The first real chance to get wet comes on Friday the 4th. The morning is dead glassy, with a 5ft swell out of the south at 10 seconds. The combined energy is 456 (moderate). Water temp is 64°, which is about average for this time of year. Long Reef is a reef break, and with light conditions, it’ll be clean as a whistle. Crowds can be a thing here sometimes, but a Friday should keep it quiet. That 10-second period means the waves will have a bit of push but still be manageable.
Saturday the 5th and Sunday the 6th mornings offer small, clean waves but the energy is low. Nothing to get excited about.
Monday the 7th morning is a gem—glassy again, 4ft south swell with a 9-second period and combined energy of 272 (moderate). That’s a solid session for anyone who can get out there. The reef will be working nicely.
Tuesday the 8th morning is a big one. 10ft south swell, combined energy of 2585 (strong), and a clean offshore wind. That’s a full-on expert day. If you’re not comfortable in heavy, powerful surf, stay on the beach.
Friday the 11th morning is another standout. 5ft south swell with a 12-second period, combined energy of 641 (moderate to strong), and glassy conditions. That’s a proper groundswell that’ll bring some real quality. The longer period will give it extra push, but the reef will handle it well.
Monday the 14th afternoon has a clean offshore wind from the west with a 4ft south swell and moderate energy of 339. Worth a look if you’re keen.
The final big one hits Friday the 18th morning—10ft south swell, 1477 combined energy (strong), and clean offshore wind. Expert territory again. The afternoon is 8ft with a fresh cross-off wind, still for the advanced crew only.
Best days for the average surfer are Friday the 4th morning, Monday the 7th morning, and Friday the 11th morning. The rest is either too small or too big.
Rusty, out.

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.
