The Lowdown
Right folks, let’s have a look at the charts. I’m Rusty, and I’ve gotta be straight with you – the next 16 days at Caerhays is a tough watch. The forecast is a flat spell with barely a ripple. The water temperature is sitting at 68°, which is a whopping 6° warmer than normal for this time of year, so it’s unseasonably warm, but that’s about the only thing going for us.
We’re looking at a long, blank run. There’s no real surf on offer at all. The first few days barely register a pulse, with wave heights stuck at 0.3 ft and a combined swell energy that’s almost non-existent, like 11 (combined energy of all swells directed here). There is a tiny uptick around the 28th of July, with Tuesday afternoon seeing a 2 ft swell from the west with a period of 9 seconds, and the energy climbs to 39 – still weak, but it’s the “biggest” of the window. The wind is clean and cross-off from the NNW, so it’s tidy, but it’s a long-period groundswell that will be breaking straight and fat on the beach. It’s really only for the most desperate longboarder, and even then, it’s a struggle.
From the 29th of July right through to the 4th of August, the models show nothing but zeros. We’re talking over a week of absolutely flat conditions. The wind is a mess of onshore and cross-shore junk, and the swell doesn’t show up. It’s a total write-off. There are no standouts, no best days, just a whole lot of nothing. When the swell is this minimal and the quality is poor, it’s not even worth mentioning the kite surfers, as there’s no wind for them either. A blank run like this is just the reality of the area sometimes.
Stay patient, boys. The ocean will wake up eventually.
Rusty.

Information about the Caerhays Surf forecast
The above surf forecast table for Caerhays provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Caerhays can be found by selecting the local surf guide option on the grey menu. Our Caerhays 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 (Caerhays) 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 Caerhays 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.
