The Lowdown
Right then, let’s have a look at what’s on offer for Caerhays. I’ll be honest with you, the outlook for the next sixteen days is a poor one. There’s not a single decent wave on the cards, and I mean that.
We kick off Wednesday the 5th of August with a tiny 2ft SW swell, but it’s getting battered by a strong 15 mph cross-offshore wind. The energy is pathetic, only 42 (weak). The water is a touch warmer than normal at 66°, but that’s the only thing going for it. The surf is just poor. That sets the tone for the whole run.
The next few days are a total write-off. Thursday the 6th through to Tuesday the 11th of August see nothing but flat, dribbly waves below 0.7ft, if that. The wind is all over the place, sometimes glassy but with no swell to speak of. It’s a real desert. The combined energy readings are all in the single digits, which is as weak as it gets.
We get a slight pulse on Wednesday the 12th of August, but it’s a messy 0.7ft with a choppy cross-onshore breeze. Not worth a second look. The same goes for the rest of that week. The end of the run, around Sunday the 16th of August, shows the biggest swell of the period at 3ft to 3ft from the SW, with a period of 6 seconds and a cross-offshore wind. The energy climbs to 62 (weak), but even then, the wave comment says "poor surf conditions." It’s just not happening.
Given the very small waves and frequent onshore winds, this setup looks more interesting for kite surfing than paddle surfing. The breaks are inconsistent and the conditions are never clean enough for a proper surf. There’s nothing to get excited about, I’m afraid. The forecasts can change, but for now, leave the boards at home.

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.
