The Lowdown
Alright, Rusty here, and I'm taking a proper look at what we've got coming down the line. Gotta be straight with you – this is a painful one.
Right from the start and all the way through the next week and a half, there’s just nothing doing. The whole 16-day window looks like a write-off for surfing at Caerhays. We’re talking about a long stretch of tiny waves, mostly under 2 ft, and a lot of them with cross-onshore or even moderate cross-off winds that just won't set up a decent ride. That combined wave energy is constantly in the low double digits, just weak (14 to 48), which tells you everything you need to know. It’s flat-lining.
We do get some clean windows, especially from the 15th to the 20th, with a few cross-off and even glassy conditions on Sunday the 20th afternoon with a light 3 mph WNW breeze. But what are you gonna ride? The swell is at a pathetic 0.7 ft with a 6-second period. It’s a non-event.
The only time things look different is way out on Monday the 28th, over a week and a half away. We see a spike in wind from the east hitting 22 mph, kicking up a lumpy, cross-shore chop. The swell height jumps to 7 ft from the ESE with a 6-second period, and the combined energy is a very strong 306 to 368. That’s a lot of power but it’s short-period, wind-driven junk. The wind and the cross-chop will make it a messy, lumpy battle. Honestly, that setup looks far more interesting for a kite surfer than a paddle surfer. For the regular punter, it’s poor.
There’s a quick drop on the 29th back to 0.7 ft with a long 14-second period, but the wind is still screaming at 22 mph. No dice.
This is one of those blank runs where it just stays poor for a long time. Forecasts can always change, but as it stands, keep the board in the car and don't even bother wetting a line.

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.
