Alright, Rusty here. Let’s have a look at what’s coming our way.

Honestly, mate, it’s a tough stretch ahead. For the next 16 days, there’s no proper surf on offer. The whole period is a write-off for a decent paddle. The first few days, from Monday the 6th through to Wednesday the 15th, are just a long run of poor surf conditions with onshore and cross-onshore winds messing up any chance of clean waves. The swell is small and weak, with period under 8 seconds, and the combined energy is mostly under 200, so nothing with any punch.

There’s a brief moment on Friday the 10th, in the morning, where it gets glassy. The swell is tiny at 2 ft from the west, 11-second period, and the combined energy is 175. It’s surfable, but very ordinary. The wind is glassy, so it’ll look calm, but you’re not getting much to ride. It’s the only morning that even rates a mention.

After that, the wind swings cross-offshore from the NNE, but the swell drops right off. By the weekend of the 12th, we’re looking at 1 ft to 2 ft waves with almost no energy. The 13th and 14th have a tiny blip of 2 ft to 2 ft swell from the west, with a long period of 12 to 13 seconds, but the combined energy is only 44 to 110—weak, gutless stuff. The afternoons are clean, but you’re basically floating on a lake.

Then around the 18th and 19th, the swell picks up to 5 ft to 6 ft from the WNW, but the period drops to 7 seconds, and the wind is howling onshore or cross-onshore at 18 to 25 mph. That’s a messy, choppy mess. The combined energy gets up to 285, but it’s all wind and chop. That setup would be more interesting for kite surfing than paddle surfing at Crab Island.

The 20th and 21st keep the same story: 5 ft to 6 ft swell, 6 to 8 seconds, cross-onshore winds, and combined energy in the 130 to 363 range. It’s strong, but ugly. Not worth a paddle.

Crab Island is a reef, fairly consistent, exposed to the west which is the optimum direction, but in this window, it’s just not happening. The water temperature is about average for the time of year, nothing unusual.

So, the long and short of it: no standout days. The best you’ll get is a glassy, weak morning on the 10th, but it’s not worth getting excited about. The rest is blown out or flat. Forecasts can change, but right now, I’d leave the board at home.

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.
