Crab Island Surf Forecast and Surf Report

Alright, surfers, Rusty here. Let’s have a look at what’s on the table for Crab Island. Normally, this reef setup can handle some serious west swell, but the forecast over the next 16 days is a real mixed bag, and honestly, there’s a lot of time where you’ll want to keep the board in the car.

We’re kicking off on Friday, August 7th, and it’s a rough start. The water’s sitting at 62°, which is pretty much normal for this time of year, but the wind is a problem. Friday morning has a moderate breeze from the WSW at 16 mph, cross-onshore, and it’s choppy. Combined wave energy is weak (57), and it’s just poor conditions. Friday afternoon sees a little more size with a 4 ft swell from the WNW, but it’s still cross-on with a 12 mph wind, and the energy bumps up to moderate (288). Still, it’s not worth paddling out for.

Saturday the 8th offers a bit of hope. The morning is clean with a light cross-offshore breeze from the SSE at 12 mph, and the swell is 3 ft from the west. The energy is moderate (181), but it’s still flagged as poor surf. The wind is doing you a favour, but the swell just isn’t organised enough.

Sunday the 9th gets a little more interesting. Sunday afternoon shows a clean 4 ft west swell with an onshore wind from the WNW at just 9 mph. The combined energy is moderate (210), and with the wind going offshore, it’s the first real window of the week. The period is 9 seconds, so it’s a short-interval windswell, but for an advanced break like Crab Island, this could offer a few fun ones if you’re in the right spot.

Looking ahead, Thursday the 13th is a standout. Thursday morning has a 6 ft west swell with a 10-second period, and the wind is blowing straight onshore from the west at 16 mph. The combined energy jumps to 569 – that’s strong wave energy. As the afternoon rolls in, the swell drops slightly to 5 ft but the energy is still strong (502). The wind stays onshore, so it’s going to be a bit lumpy, but for a reef break that loves west swell, this is the biggest pulse of the whole forecast. It’s advanced territory, so don’t take the 6 ft stuff lightly.

The middle of the second week, around August 15th and 16th, sees a persistent 5 ft to 5 ft west swell, but the wind is a mess. Saturday the 15th has an onshore breeze, and by Sunday the 16th, we’re looking at a near gale from the southwest at 31 mph, blowing it out completely. The energy is moderate (298), but the wind is a dealbreaker.

The absolute best bet for the whole 16-day window is probably the late afternoon of Saturday, August 22nd. The swell pushes up to 7 ft from the west, with a 10-second period and a combined energy of 710 (very strong). The wind is onshore from the WNW at 22 mph, so it’s not glassy, but for a powerful, consistent reef break, this is the biggest swell of the whole run. 7 ft is too big for beginners, and even for the average surfer, it’s going to be a handful. Only experts need apply.

In summary, if you’re an advanced surfer looking for a challenge, keep your eyes on Thursday the 13th for the first big pulse, and Saturday the 22nd for the biggest swell. Crowds are often an issue here, so you won’t be alone. The rest of the time is mostly poor, with plenty of choppy, cross-on wind. This is a reef break, so the long-period swells (when they show up) should wrap in nicely, but the wind is the enemy for most of this forecast.
