The Lowdown
Alright, let’s get real about Caerhays. It’s a lean run, no two ways about it. We’re looking at a proper flat spell for the next week and a half. The swell is tiny, under 2 feet, and the wind is mostly cross or onshore, chopping up any hope. The wave energy is weak, barely registering, with values like 10 (weak) or 7 (weak). It’s a tough watch.
The first glimmer of hope comes in the second week. Saturday, the 8th of August, sees a little 2ft swell from the SSW in the morning, but the wind is light and offshore from the NE. That’s clean. The combined energy is a low 8 (weak). The one to circle is the afternoon of the 8th. The swell is still around 2ft from the S, and the wind goes light and cross-offshore from the WNW. That’s the cleanest it’s going to get. The wave energy bumps up to 22 (weak), which is the best we’ll see. It’s not going to be a world-beater, but it’s something to wet the line.
Then, Monday the 10th of August has a morning of tiny 0.6ft SW swell, but with a light cross-offshore breeze from the NE, it’ll be clean. The energy is 15 (weak). Small, but clean.
So, the bottom line is: the first week is a total bust. The only real window is the afternoon of Saturday the 8th. It’s small, but it’ll be glassy. If you’re jonesing, that’s your moment. Water temp is about what you’d expect for this time of year.

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.
