The Lowdown

Alright folks, Rusty here. Let’s get into it. We’re looking at Crab Island, and honestly, it’s a tough stretch ahead. The first week and a half is pretty much a write-off for paddle surfing, with a whole lot of wind-ruined, weak, and messy conditions. The best window we’ve got, and it’s a bit of a gamble, is the weekend of the 1st of August.

Starting off now, through the end of July, the wind is relentless. It’s cross-on, onshore, or side-shore from the W, NW, and SW for days on end, with winds between 12 mph and 22 mph. The swell is small—between 1 ft and 3 ft—with poor energy. That’s a no-go. The water temp is 61°, which is pretty normal for this time of year, so that’s not the issue.

On the 25th of July, the swell jumps up a bit, with 6 ft to 6 ft WNW swell and energy rising, but the wind is still a mess (15-22 mph cross-on). It’s powerful, but it’s going to be a lumpy, blown-out mess. That’s more of a kite-surfing setup than anything for a paddle board.

We get a bit of a reprieve on the morning of the 30th of July. The wind goes glassy from the ENE at 3 mph, with a 3 ft WNW swell. The energy is weak, but the glassy conditions mean it could be fun for a log or a longboard, if you’re desperate. But be warned, the crowds are often here, so you won’t be alone.

The real standout might be the morning of the 1st of August. We’ve got a 8 ft swell from the WSW, with a period of 9 seconds and very strong energy. That’s a strong pulse. The wind is clean, cross-off from the SE at 15 mph. Now, 8 ft is big, expert territory, especially for a reef break. The period is short, so it’ll be a bit racy and won’t have that long, drawn-out power. But for the advanced crew, this is the best on offer. The swell direction is WSW, which is a bit off the optimum W direction, but it’s close enough to deliver.

After that, the 31st of July afternoon looks funny: a 6 ft SW swell with a period of just 6 seconds and moderate energy. The wind is light from the S, so it stays clean, but that period is so short it’ll be a choppy, weak wave, more for the novelty than quality.

The rest of the forecast into the first week of August falls away again. The 2nd of August has a 5 ft swell, but it’s cross-on from the SW with 15 mph winds, so it’s messy. From the 3rd of August onward, it’s back to tiny, weak, and wind-affected surf, with heights dropping to 1 ft. Not worth getting wet for.

So, to sum it up: the wait is long. The best bet is the morning of the 1st of August for the experienced crew, with a big, clean, but short-period swell. The 30th of July morning is a consolation prize for the patient ones on a longboard. Otherwise, it’s a long, dry spell.

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.
