The Lowdown
Alright, Rusty here. Gotta be straight with you — this stretch is looking pretty grim. Through the entire 16-day window, there's honestly nothing worth paddling out for. The conditions are just not playing ball. There's no standout, no hidden gem, nothing. It's a long, flat spell with a few tiny pulses that never line up with decent wind.
Right out of the gate, from Monday the 10th through to Saturday the 23rd, it's a mess. The wind is mostly cross or cross-onshore from the north-northwest, blowing between 9 and 19 mph. Swell heights struggle to even hit 4 ft, and when they do, the period is short or the wind chops it up. The combined wave energy is low, usually under 165, so it's weak and gutless. Mondays through to Fridays are just poor — choppy, messy, nothing to get excited about.
Saturday the 15th sees a tiny bump: 4 ft from the NW with a 9-second period, but the cross-offshore wind keeps it bumpy. No thanks.
Sunday the 16th morning goes glassy, but the swell drops to a pathetic 0.3 ft from the SW with a 16-second period — that groundswell has no size. So it’s flat and clean, not surfable.
From Sunday the 16th all the way through to Tuesday the 25th, we are looking at tiny, near-flat conditions. Swell hangs around 0.3 ft to 0.7 ft, occasionally reaching 1 ft. The wind is mainly light cross or cross-onshore. The wave energy barely hits 41 — it’s a desert out there.
Thursday the 20th afternoon offers a flicker: 3 ft from the NW with an 11-second period and 172 energy, but the wind is onshore. Still no good.
Friday the 21st morning is the closest thing to a pulse: 4 ft from the NW, 11-second period, 297 energy. But it’s cross-onshore from the NNW at 9 mph, so it’s choppy. Not worth it.
After that, it fades back into nothing. Saturday the 22nd has a bit of knee-high dribble, but it’s cross-shore and weak (energy 163). Sunday the 23rd and Monday the 24th are even worse, with tiny swell and chop.
Tuesday the 25th ends the forecast with 1 ft, WNW, 9 seconds, and 35 energy, plus a fresh cross-shore wind at 19 mph. Unrideable.
The only break in the whole file is "Reef" — a reef break rated for advanced surfers only. It’s fairly consistent but exposed to the swell, and the optimum direction is SW. Unfortunately, the swell we get is mostly from the NW and WNW, never matching that sweet spot. With such small, weak swells, it’s not breaking properly at all.
Water temperature? There's no anomaly data given, so assume it’s average for this time of year.
Bottom line: don’t waste your time. This area is having a real dry spell. Stick a pin in it, check back later — forecasts can change.

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.
