The Lowdown
Right then, let’s have a look at what’s on offer. The whole 16-day window is a bit of a write-off for Caerhays, to be honest. There’s a real flat spell that stretches from the start all the way through the end of July, so you’re looking at a long gap with no real surf. The swell energy is nearly non-existent, just a few tiny pulses with combined energy values in the teens and single digits – that’s basically nothing. The water’s sitting at 67° with a 6° anomaly, which is much warmer than normal for this time of year, but that’s about the only thing going for it.
The first real sniff of something comes on the 24th of July, with a 4ft swell from the SSW. That’s a moderate energy pulse (135), but the period is only 7 seconds, so it’s weak and short-period. The wind is a fresh cross-onshore, which will chop it up and make it a messy, lumpy affair. It’s poor surf conditions, nothing more. The next day, the 25th, drops to 2ft and the wind stays onshore, so it’s still not worth jumping in.
Honestly, there’s nothing here that stands out. Caerhays is inconsistent and the forecast is a total blank run. For a spot like this, a dry spell is more normal, so it’s not a huge surprise. The best you can hope for is a quick glance at the water on the 24th, but even then, it’s a kite-surfing setup rather than a paddle session. Keep your expectations low, and check back in a few days.

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.
