The Lowdown
Alright folks, Rusty here. Let’s look at what we’ve got for the next couple of weeks, and I’ll be straight with you – it’s a tough one.
First up, we’re looking at a proper dry spell. From now until the end of July, there’s really nothing to get excited about. The surf is tiny, barely a ripple, with heights hanging around 0.3 ft for days on end. The combined energy is weak, sitting in the single digits (10 or less) for most of that time. It’s frustrating, but that’s how it goes sometimes.
Now, there is a flicker of hope right at the very end. On Friday, the 31st of July, we see a pulse of new swell arrive. The morning at Caerhays (United Kingdom) will see a jump to 5 ft from the WSW, with a period of 6 seconds. The combined energy hits 202, which is solid moderate energy. However, the wind is light and cross-shore, so there will be a bit of bump on it. That morning window is the best on offer in the whole outlook, but the short period and cross-shore wind mean it’s not going to be perfect. It’s a bit of a gamble, and the sets will be inconsistent. This size is still okay for most surfers, not too big for beginners.
After that morning, it drops off again. The rest of the first week of August looks weak, with small 0.7 ft to 1 ft swells and poor conditions. The offshore winds we see on Tuesday, the 4th of August, are clean and nice, but there’s barely any swell to ride.
So, to be honest, with the data we have, the only real chance to get wet is that Friday morning, the 31st of July. It’s not a standout classic, but it’s the only game in town. The rest of the 16 days is a write-off for any decent surf. Keep your eyes on the forecast, because it tends not to stay this flat for long, but for now, it’s pretty grim.

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.
