The Lowdown
G'day, I'm Rusty. Let's be straight with you – this 16-day window for this spot is a tough one. We're looking at a stretch of mostly small, choppy, and messy surf. The water temp is sitting at 70°, which is about average for this time of year, so at least you won't be shivering while you're waiting for a wave that's not really there.
The pattern starts on the afternoon of the 27th of July, and it's a slow grind. There's a tiny 1ft swell from the WNW, but with a cross-onshore breeze, it's just bumpy and weak. The combined energy is a measly 15 (weak energy), and it's all labelled "poor surf conditions." Honestly, you're better off checking the tide pools.
Tuesday the 28th and Wednesday the 29th are more of the same. We're looking at 0.7ft to 1ft of swell, period hanging around 8 to 11 seconds. The wind stays cross or cross-on, keeping everything choppy. The energy barely breaks 30 (still weak). It's not surfable.
Thursday the 30th through to Sunday the 3rd of August sees a slight bump in size to 1ft to 2ft, but that's still tiny. The wind is moderate and cross-shore, so it's lumpy. The combined energy climbs into the 50s and then 80s (still weak). It's a kite surfer's breeze, not a surfer's wave.
The only real change comes on the 4th and 5th of August. We get a pulse of 4ft swell from the WNW, but the period drops to a short 8 seconds. The combined energy jumps to 170 (moderate wave energy), which sounds promising, but the wind is still cross-on and the surf report screams "poor surf conditions." That short period means it's going to be weak and crumbly, not the powerful lines you'd want for a reef.
From the 6th of August onwards, it's a total wipeout. The swell drops back to 1ft or less, and by the 8th of August, we're looking at 0.7ft. Then, from the 9th to the 11th of August, there's zero swell. The wind is howling at 25 to 28 mph from the north, making it completely unsurfable. It's a solid 4-day gap of nothing.
There's no standout window here. If you're desperate, the morning of the 4th of August has the most size, but with the short period and onshore wind, it's a long shot. Otherwise, it's a blank run. This area just doesn't get much going when the conditions are like this. Hang tight, forecasts can change.
Rusty.

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.
