The Lowdown
Alright, Rusty here, with a look at what's coming our way for Caerhays over the next couple of weeks.
To be straight with you, it's a pretty quiet stretch. The first week and a half is looking mostly flat or just tiny, with a lot of choppy, onshore wind messing up the little bumps we do get. You're looking at a long gap from now until around the 15th of August where there's just nothing worth paddling out for. The water is a touch warmer than normal for this time of year, sitting at 66°F, but that's about the only positive.
We do finally see a flicker of life on the afternoon of Saturday the 15th. The swell bumps up to about 3ft, pushing in from the SW, and the wind goes glassy, which is a rare treat. The energy is still weak (75), but it's the cleanest, most surfable window we get. The swell period is a short 7 seconds, so it won't be anything special, but for a log or a foamie, it'll be a session. The break is inconsistent, so you'll be waiting, but that glassy surface makes it worth the patience. It's a fairly exposed spot, so it can catch a little something, but crowds are possible here.
Sunday the 16th is a step down in quality, with cross-shore winds and a smaller 2ft swell. The cleanest conditions seem to be the offshore winds around the 13th and 14th, but with only 0.6ft to 2ft of swell, it's just too small to get excited about.
So, the one and only real standout is the late afternoon of Saturday the 15th. It's not a big swell, but it's the only time the stars align for a clean, glassy session. Get yourself a longboard and make the most of it.

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.
