Alright, Rusty here. Let’s look at what’s cooking for the next sixteen days.
First up: there’s no surf worth mentioning until at least the second week. We’ve got a long stretch of flat or poor conditions ahead. The only break in the game is Crab Island (Clare), a heavy reef that needs a solid west swell. But the conditions are working against it.
We kick off on Tuesday the 7th of July with a west swell around 4ft, period 9 seconds. Water temp is 61°F, about a touch warmer than normal for this time of year. That’s nice, but the wind’s blowing from the WSW at 12 mph, cross-on, making it choppy. Energy is moderate (209), but the score is zero. That pattern holds through Thursday the 9th – some size, but always cross-on wind, always poor.
Friday the 10th sees the swell drop to around 2ft, period stretches to 11 seconds – more of a groundswell – and the wind swings light cross-shore from the NNW at just 3 mph. Energy is moderate (206), but the wave height is small. It’s marginal. After that, the swell collapses. From Saturday the 11th through Tuesday the 14th, we’re talking waves under 2ft, mostly 0.3ft to 2ft. Energy drops into double and single digits – that’s weak. There’s a brief moment on Tuesday morning the 14th with 2ft and offshore wind, but not enough power for Crab Island.
From Wednesday the 15th onward, it’s basically flat. Tiny waves, barely a bump. The combined energy figures are below 30 most days. Thursday the 16th has a period of 14 seconds but with only 0.3ft of swell, it’s not going to break. Glassy conditions that morning (3 mph from the west), but no wave to ride.
There’s a slight return of energy on Wednesday the 22nd of July, with 3ft from the WNW, period 7 seconds, and cross-offshore winds. Energy hits 121, which is moderate. That afternoon the wind turns cross-on and it gets choppy again. So if you’re keen, that morning might give you something small and clean, but it’s only for the dedicated and the experienced.
Bottom line: over these sixteen days, there’s no standout session. Everything’s tiny, or blown out, or both. The forecast confidence is solid for the near term, and it’s telling it like it is – there’s nothing to get excited about. Keep watching the charts, but for now, we wait.

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.
