Alright, Rusty here. Let's have a look at what's on the table for the next couple of weeks.
Alright mate, I'm not gonna lie to you – this is a rough stretch for a paddle. The swell's just not showing up with any kind of quality, and the wind's going to be a pain for most of it. We're looking at a long, long wait. The first solid sign of life doesn't show up until late in the game, and even then, it's a bit of a gamble.
For the first week and a half, it's a total write-off. We're talking about a solid 10 days from July 12th right through to July 21st where the waves are tiny, mostly under 2ft, and the wind's either cross-off or onshore. The combined wave energy is pathetic, barely cracking 60 for the whole period. The best you'll get is a 1.6ft wave on Tuesday the 14th with a light offshore wind, but honestly, it's described as "surfable waves but very ordinary conditions" – and that's the highlight. The water temp is sitting at 61.2°F, which is a touch warmer than usual for this time of year, but that's not enough to get excited about when the surf is flat. Don't even bother with the board.
Then we get a bit of a bump. From July 22nd, the swell starts to push up. On Wednesday the 22nd, we see 3.6ft from the WNW with a moderate energy reading of 240, but it's a fresh cross-onshore breeze, making it choppy and lumpy. The 23rd and 24th bring a bit more size, up to 4.6ft, but the wind is a mess – strong onshore and cross-shore, with the raw energy climbing to 250. This is straight-up messy, and honestly, for a exposed reef break like Crab Island, that onshore wind is going to ruin it. If you're considering a kite, this might be more your scene than a surfboard.
July 25th is the only real standout. We're looking at 4.9ft to 5.2ft from the WSW, with energy hitting 306. That's the most power we'll see. The problem? The wind is still a fresh cross-onshore (19 mph), so it's going to be lumpy. But, if you're an advanced surfer who knows Crab Island (Clare), and you're desperate, this is your window. It's a 5/5 advanced reef, exposed to the W, and the optimum swell direction is from the W. The swell direction is spot on. But with that wind, it's going to be a battle. The crowds are often, so expect company.
After that, it drops off again. The 26th is a write-off with strong winds, and the 27th is back to under 3ft and messy. It's a grim outlook, lads. The best advice is to wait for the 25th, and even then, keep your expectations low.

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.
