The Lowdown
Right, this is a quiet one for Caerhays. A real bummer, to be honest. The next two weeks are looking pretty flat, so don’t go getting your hopes up for any decent waves. We’ve got a long gap here with nothing worth paddling out for.
Looking at the whole 16-day run, the very end of the period, on Saturday, the 19th of September, we see a bit of a pulse. It’s the only standout in the whole window. The swell jumps to 5ft from the ESE with a short period of 6 seconds. The combined swell energy is moderate at 154, so there’s some push there, but it’s a short-period, wind-affected swell. The water is a touch warmer than normal at 64°F. The winds on that Saturday morning are ultra-light from the ESE, which would make it glassy clean, but it’s a cross-on direction for the break. The afternoon sees a SE wind at just 6 mph, keeping it light.
It’s just a couple of days of small, weak surf. Don't expect any barrels, but if you’re desperate for a splash, it’s the only window on the board. Everything before that is a write-off. The wait is well over a week from now for that Saturday.

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.
