The Lowdown
Alright, folks, Rusty here. Let’s have a look at what’s cookin' for Caerhays over the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s a long, dry spell. We’re looking at a real flat patch that stretches from the 9th of September all the way through to the 19th. That’s well over a week of pretty much nothing worth paddling out for. The swell is tiny, mostly under 2 ft, and when there is a little bump, the wind is usually trashin' it. It’s proper frustrating.
The water temp is sitting at 65°, which is a touch warmer than normal for this time of year, so at least it’ll be pleasant just sittin' out there if you’re keen for a float.
Now, the first glimmer of hope doesn’t show up until the 20th of September. The Sunday morning session is the only thing that even registers on the scale. We’ve got a 1 ft swell rollin' in from the WSW with a very long period of 15 seconds. That’s a proper groundswell, which often means longer lulls but better shaped waves when they come. The combined wave energy is still weak at 58, but the wind is a light cross-offshore from the NW, keepin' it clean. The conditions are described as "surfable waves but very ordinary," so we’re not talkin' about a classic, but it’s the only window where you might get a few fun ones.
The rest of the forecast after that? It’s more of the same – tiny, weak, and wind-affected. Honestly, for the next 16 days, your best bet is to keep an eye on the sky, because the ocean isn't giving you much. The only standout is that Sunday morning on the 20th, and even then, keep your expectations low. It’s a spot that’s inconsistent anyway, so a blank run like this isn’t totally out of the blue.
Rusty, signing off.

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.
