The Lowdown
Alright folks, Rusty here. Let’s have a look at what Caerhays has in store for us over the next couple of weeks.
Right off the bat, I gotta say, it’s a grim picture. There’s no surf to get excited about at all for this whole sixteen-day stretch. We’re looking at a long, flat run here. The first day worth even mentioning is Saturday the 5th, but with just a tiny 1 ft swell from the SW and a short period of 7 seconds, it’s a total no-go. The water is sitting at 64°, which is a touch warmer than normal for this time of year, but that’s the only highlight.
We go straight into Sunday the 6th with even smaller, messier waves and onshore winds. Monday the 7th gives us a little bump in energy, but the swell height is still a pathetic 2 ft. The wind is cross-offshore from the WNW, so it would be clean, but there’s just nothing to ride. The rest of the first week and all of the second week are basically flat or knee-high dribble. There’s a day on Friday the 11th where the wind is fresh and cross-off, but again, the swell is tiny at 3 ft with a 6-second period – not enough grunt to make it worthwhile. We do get some glassy conditions on a few mornings, like Sunday the 13th and Monday the 14th, but for waves less than 1 ft? You’d be better off taking a nap.
The whole second week, from the 14th onwards, is flat as a tack. There’s nothing. No standouts. No hope spots. This is just one of those blank runs for the area. Forecasts can change, but as it stands now, leave the board in the car and maybe take up fishing. It’s that quiet.

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.
