The Lowdown
Alright, let's talk about Caerhays. Truth is, it's looking pretty flat and uninspiring for the next couple of weeks. The swell is barely a whisper, and the wave energy readings are all tiny, stuck in the low double digits or even single digits for most of the run. We're talking a combined energy of just 22 on Saturday morning, and it's downhill from there. The water's sitting at 64°, which is a touch warmer than normal for this time of year, but that's the only bit of good news.
We start off on Saturday, the 5th of September. There's a tiny 1-foot swell from the SW with a short period of 7 seconds, and a cross-offshore wind keeping it clean. But it's just too small and weak to bother with. The whole first week is a washout, with nothing but "poor surf conditions" and tiny, inconsistent waves. The only real glimmer of hope comes on the 14th of September, a Monday. We've got a clean 3-foot swell from the ESE, with a light breeze creating clean conditions. The combined energy is a more respectable 43, and the wind is a cross-off from the NNW. It's not a big swell, but it's the best of a bad lot, and the conditions are clean. After that, it drops back to almost nothing for the rest of the period.
Honestly, for the next two weeks, you're better off checking the forecast again in a few days. There's just nothing to get excited about here.

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.
