Alright, let’s get into it. This is Rusty, and I’m looking at the 16-day window for Long Reef.
Alright, straight up, the first week is a bit of a write-off. We’ve got a long stretch of days with next to nothing happening. From Sunday the 12th right through to Tuesday the 14th, the swell is tiny, barely a ripple, with clean conditions but no power behind it. Not worth paddling out for.
We finally see a pulse of energy on Wednesday the 15th, but it’s a bit of a brute. A solid 10ft southerly swell rolls in, but with a short period of 9 seconds, it’s going to be a bit of a washing machine. The combined wave energy is strong (1247 in the morning, 1419 in the afternoon), so there’s plenty of water moving around, but the wind is cross-offshore, keeping it a bit cleaner. This is definitely for the experienced crew only; 10ft is too much for most. Thursday the 16th and Friday the 17th are messy, with onshore winds chopping up the 6-7ft swell into a real jumble. Not worth a look.
Now, after a few more days of average, knee-to-waist high slop, we get to the real standout. The best session in this whole outlook is Sunday the 19th. The morning is looking absolutely magic. We’ve got a solid 8ft easterly groundswell, with a long period of 11 seconds, which means real, powerful lines. The combined wave energy is massive (1758), so you’ll feel the push. The best part? Glassy conditions. Zero wind. That’s going to create some beautiful, clean, peeling waves. This is a serious session for experienced surfers at Long Reef (Long Reef). The water temp is 65°, which is about average for the time of year, so a 3/2 wetsuit should be fine.
Monday the 20th is still decent, with a 7ft easterly swell and a crisp, clean offshore from the northwest. The energy is still strong (1075), and the conditions are clean, making it a solid follow-up session. It’s a touch smaller for the rest of the week, with knee-to-waist high waves and clean conditions, but nothing to write home about.
So, to sum it up: take the first week off. The only real highlight is that Sunday the 19th. Get out there for the glassy morning session – it’s the one to circle on the calendar.

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.
