The Lowdown
Right, folks, Rusty here. Let’s have a look at this forecast for Caerhays, and I’ll be straight with you – it’s a tough one. The whole 16-day window is a real struggle for any proper surf. We’ve got a long, flat gap right at the start. From Tuesday the 21st of July right through to Saturday the 1st of August, the swell is tiny, barely a ripple. Don’t even bother checking the charts for that stretch; it’s more of a swimming or sunbathing deal than a surf session.
The water temp at Caerhays is sitting at 68°F right now, which is a whopping 6°F warmer than average for this time of year. Properly unusual – feels like a warm bath out there.
Now, the first faint glimmer of hope shows up on Sunday the 2nd of August. We see a pulse of 3ft swell from the SSW, but with a short, weak period of only 5 seconds. The wind is clean and cross-off from the WNW, which is a major positive for the surface texture. The combined energy is weak (47 on Sunday morning, 46 in the afternoon). This is really marginal stuff, but it’s the best the whole window has to offer.
Monday the 3rd of August afternoon is the only time the score even nudges up. The swell drops to 2ft from the W, period is 8 seconds, and the wind is still a clean cross-off. The combined energy hits 80 (moderate wave energy). The report says “surfable waves but very ordinary conditions,” which is about right. It’s not going to be a classic, but if you’re desperate for a paddle and a few soft, crumbly waves, this is your moment. The break is inconsistent, so don’t expect a set every few minutes, and crowds are possible here.
After that little blip, it’s back to flat and messy for the rest of the window. The wind swings onshore or cross-onshore, and the swell disappears completely. There’s a real kicker on Friday the 31st of July with strong onshore winds and rain, but the swell is zero – that’s a skip day for sure.
So, to be honest, there’s no standout session here. The best on offer is that Monday the 3rd of August afternoon, but keep your expectations low. It’s a weak, short-period swell with a bit of clean wind. For the rest of the 16 days, leave the board at home and go for a swim.
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.
