The Lowdown
G'day, I'm Rusty, and I've got to be straight with you—this outlook for Crab Island is a tough one to swallow. We're looking at a real quiet stretch ahead, with no decent surf options on the cards for the full 16 days. The water temperature is sitting at 62°F which is pretty much normal for this time of year, so nothing weird there, but the waves just aren't turning up.
Right now, and for the next few days, there's barely a ripple. We've got tiny swell around 1ft to 2ft coming from the west-southwest with weak energy reading between 11 and 67. Winds are mostly cross-off or light, but it doesn't matter when there's no real push. The surf is just too small and poor.
Come Wednesday, August 5th, we see a bit of a jump in size with swell hitting 8ft from the west-northwest, and the combined energy spikes to 611. But don't get excited—the period is only 7 seconds, so it's a short, weak wind swell, and the wind is a fresh cross-onshore from the northwest at 22 mph. That's going to be lumpy and messy, more suited to kite surfers than paddle surfers at this exposed reef setup. It's not for the faint-hearted either, as that 8ft is too big for beginners, and the conditions are just poor.
The rest of the run stays pretty grim. Through the second week, swell runs small again, mostly under 3ft, with onshore winds and weak energy. There's a little bump on the 15th and 16th, with swell up to 8ft from the west, and energy hitting 1196, but again it's short period (10 seconds), and the wind is onshore at 25 km/h. That's a messy, expert-only scene with poor surf conditions written all over it.
Bottom line: Crab Island is a write-off for the next 16 days. Several breaks in the area are fairly consistent, so this blank run is a bit of an anomaly—forecasts can always change, but for now, keep the boards in the shed.

Information about the Crab Island Surf forecast
The above surf forecast table for Crab Island provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Crab Island can be found by selecting the local surf guide option on the grey menu. Our Crab Island 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 (Crab Island) 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 Crab Island 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.
