The Lowdown
Right then, let's have a look at what's on offer for Caerhays over the next couple of weeks. I gotta be straight with you – it's a tough stretch. The models are showing a real flat spell, with nothing that's going to get the heart racing. The combined swell energy is a measly 10 (moderate wave energy) at best in the early days, and it barely gets out of the double digits. We're looking at a long gap of near-zero surf.
We start off on Thursday, the 6th of August, with a tiny 1ft SW swell, but it's poor surf conditions. The wind is a cross-off from the NW, so it's clean, but there's just nothing to ride. That theme continues right through the first week. Friday the 7th has a glassy morning with a 0.3ft S swell, but it's a 15-second period swell – that's a long period groundswell, but it's so small it won't wrap in properly. The water is about average for this time of year.
We've got a long gap of nothing. Day after day of poor surf conditions. The 14th of August, Friday afternoon, is the first time we see a little bump – a 2ft W swell, with the combined energy hitting 100 (moderate wave energy). The wind is a clean cross-off from the WNW, so it's the best looking window in the whole run, but it's still a poor surf conditions call. For a beginner, 2ft is fine, but it's not going to be anything special.
Saturday the 15th keeps the 1ft SW swell, but it's inconsistent. The spot is already inconsistent, so when it's that small, it's a real gamble.
The last week of the forecast, into the 20th and 21st of August, we're back to tiny 0.3ft and 0.7ft swells, mostly clean but with no power. The combined energy drops right down to 6 or 12 (weak wave energy).
Honestly, there's no standout here. The closest we get to a "go" day is the afternoon of Friday the 14th, with that 2ft W swell and clean cross-off winds. For a few small waves on a longboard, it might be worth a look. But don't expect anything to get your heart pumping. The set-up at Caerhays is a beach break, so with the long period swells we see later on (15-16 seconds), it's going to break too straight for a proper wave. The rest of the time, it's a flat spell.

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.
