The Lowdown
Alright, Rusty here again – now in feet and miles per hour.
We’ve got a long dry spell ahead at Crab Island. From now through the 23rd of July, it’s tiny and weak. Swell barely reaches 1–2 ft, periods short, and the combined energy is in the 20–30 range – not enough to paddle for. The wind occasionally goes offshore or cross-off, but it’s just not making waves. Crowds are sometimes a factor here, but with conditions like this you’ll probably have the place to yourself.
Then Thursday morning, 24th July, that’s the day to circle. Glassy conditions, a light ENE breeze, and a 5 ft swell from the WNW with a 13-second period – that’s proper groundswell. Combined energy hits 806 (moderate). This exposed west-facing reef will be firing clean. The Friday 25th afternoon also looks good with a glassy calm and a 4 ft W swell at 11 seconds, energy 410, but Thursday morning is the real stand-out.
After that, it gets big and ugly. From the 26th onward we’re seeing 7–8 ft waves, but with strong onshore winds and rough, lumpy conditions – only for experts and even then it’s pretty horrible. The energy jumps into the four-digit range (830–1001) but the wind ruins it.
Bottom line: hit Thursday morning 24th July. That’s your best shot. Otherwise, it’s a long wait and then a messy finish. Stay tuned – forecasts can change.
Rusty.

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.
