The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – for the next few days, Long Reef is pretty ordinary. The swell is tiny and the conditions are just not coming together. We’ve got a bit of a wait on our hands.
The first real chance to paddle out comes on Friday, 4 September. The morning is looking clean with a glassy surface and a small 4ft south swell coming in. The combined energy is moderate (327), and the water temp is about average for this time of year at 64°, so nothing unusual there. The wind is almost nothing – glassy, which is a rare treat. It’s not big, but it’s the best the week has to offer.
Then on Sunday, 6 September, the morning has a 4ft south swell, period up to 11 seconds, and the energy is a bit higher (336). The wind is a light cross-off, so it’ll be clean. Still not a standout, but a solid session.
Monday, 7 September morning is similar – 4ft south swell, light cross-off, clean lines. The energy is solid (364). It’s a nice run of mornings.
Now, Tuesday, 8 September morning – this is the one to circle. The swell jumps to 6ft from the south, period around 9 seconds, and the combined energy is strong (546). It’s a clean, light offshore breeze. That’s a proper fun day, but at 6ft, it’s getting a bit much for beginners. For the experienced crew, this is the pick of the first week.
The second week is a bit of a mixed bag. Wednesday, 16 September morning has a 6ft east swell, light offshore wind, and moderate energy (468). That’s clean and punchy, but a week and a half away, so keep an eye on it. The Thursday, 17 September morning is a bit smaller at 5ft, with a light cross-shore breeze, but the energy is still decent (364). Nothing mind-blowing, but it’s surfable.
Overall, the best on offer is the morning of Tuesday, 8 September – solid 6ft south swell, clean offshore wind, and good energy. Friday morning the 4th is your glassy, smaller option if you want something easy. The rest of the window is mostly choppy, onshore, or just too small to get excited about.
Stay stoked,
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.
