The Lowdown
Alright folks, Rusty here. Gotta be straight with you – looking at the 16-day window, it's a tough stretch for this spot. The forecast is basically a long, quiet lull with no real surf to get excited about. We're looking at a solid run of days where the waves just aren't cooperating.
The outlook starts on Monday, August 3rd, with small, messy conditions. Swell is tiny at 2ft from the west, and the wind is a cross-onshore breeze, making for a choppy surface. The combined energy is barely a whisper at (60). It's a write-off. Tuesday the 4th sees a slight bump in swell to 3ft from the west-northwest, but the wind stays onshore and the period is short, so don't expect much. The energy ticks up a bit to (132), but it's still poor.
The rest of the first week and into the second is more of the same. Wednesday the 5th through to the weekend of the 9th and 10th is a real drag. Winds are mostly cross-shore or cross-onshore, often moderate to fresh, with swell heights struggling to reach 3ft. The energy readings are all in the two-digit range, mostly below 50, which tells you just how weak everything is. There's a slight uptick on Wednesday the 12th with a 3ft west swell and a period of 9 seconds, giving us a moderate energy reading of (123), but the wind is still cross-shore making it lumpy. It's still a poor surf call.
Looking further out, the situation doesn't improve. The final days from the 15th to the 18th of August are dominated by very short-period windswell and strong, choppy winds. The swell drops to 0.3ft on the 15th, and while the period jumps to 20 seconds, it's a ghost swell with no energy (33) and doesn't offer anything surfable. The combined energy during this whole period rarely breaks into triple digits.
So, the honest truth? There are no standouts. No best days. The whole 16-day window is a blank. For a reef setup that's exposed to the southwest, we're just not getting the right direction or any solid groundswell. The wind is almost always messing things up. It's a real bummer, but this area can go quiet for a stretch. Forecasts can change, but right now, I'd save the wax for another time.

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.
