The Lowdown
Alright, folks, let's be honest. Crab Island is in a real slump here. From Wednesday the 29th of July, we are staring at a long, dry spell with barely a ripple. For over a week, it's just tiny, grovelly swell and messy winds. Not much to paddle for.
The only flicker of life comes on Saturday the 8th of August. That morning, the wind goes completely dead. It's going to be glassy. We've got a tiny 0.8m swell from the WNW, with an 8-second period and combined energy of 92. It's not going to be pumping, but with clean, smooth water, those little waves will be ridable and fun. It’s described as “surfable but very ordinary,” and honestly, that's the highlight of the whole 16 days. The afternoon blows up with a light NW breeze that will mess it up again.
Water temperature is pretty much what you'd expect for this time of year. Nothing weird there. It's a reef setup, so that morning of glassy conditions will give you the cleanest faces. For a break that's usually fairly consistent, this is a long quiet period. It won't stay this way forever, so keep your hopes up.

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.
