The Lowdown
Right then, let's have a look at what's on offer for Caerhays over the next couple of weeks.
Honestly, it's a pretty bleak picture for the foreseeable. We've got a long, long stretch of tiny, weak swell that's not going to do much for anyone. The water is sitting at 66°, which is a touch warmer than usual for this time of the year, but that's about the only good news.
The first real hint of anything worth paddling out for doesn't show up until Saturday the 22nd of August. That morning, we see a bit of a spike in energy with a combined swell energy reading of 209 – that's moderate. The swell is coming from the southwest at 3ft, with a 12-second period, and the wind is offshore from the NNW at 12 mph. It's not perfect, and the conditions are described as "very ordinary", but it's easily the best on offer in this whole 16-day window. The offshore wind will keep it clean, though the long period might make it a bit straight at the beach.
Following that, Sunday the 23rd has a small, long-period (17 seconds) groundswell from the southwest, but it's only 1.0ft in the afternoon. The combined energy is only 70. There's a light cross-offshore breeze, so it'll look pretty, but you'll be bouncing on your board more than surfing.
Everything before the 22nd is flat, and after Sunday the 23rd it drops right off again. There's just nothing consistent about this stretch. For a spot like Caerhays, which can be inconsistent, this blank run is more or less par for the course when the charts look like this. Don't get your hopes up for any big sessions.

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.
