The Lowdown
Alright, let’s see what’s going on with Caerhays. I’m not gonna sugarcoat it – the next couple of weeks are looking pretty grim for a proper paddle. We’ve got a long stretch of tiny, weak leftovers, and the first real sign of life doesn’t show up until the early days of August.
Looking at the whole picture, this is a quiet period. The first week and a half is basically a write-off. From Thursday the 23rd of July right through until the 5th of August, we’re stuck with wave heights hovering around 0.3 ft to 0.7 ft. The swell energy is dirt-low, mostly single-digit figures (like 12, 4, 5, 3), and the periods are short and confused. You’d be floating around on a lake. The water temp is sitting at a balmy 68°, which is a whopping 6° warmer than usual for this time of year – that’s really unusual, and it’s the one thing that’ll feel nice if you’re just having a swim.
Now, there’s a glimmer on Sunday the 2nd of August. The afternoon sees a bump from the WSW at 6 ft, with a period of 7 seconds. That’s a short-period windswell, but the energy jumps to 347 (moderate energy). However, the wind is a messy cross-shore at 16 mph, so it’s going to be lumpy and crossed-up. If you’re an expert on a bigger board, you might find something, but it’s not going to be clean. Honestly, with that significant swell and a beach setup, this looks more interesting for kite surfing than a paddle session.
The only real standout – and I say that carefully – is the tail end of the window. Wednesday the 5th of August brings a morning of 3 ft from the ESE at a 5-second period, with clean, cross-off NW wind at 6 mph. The energy is still weak (46), but it’s glassy and clean. The best of the lot is Thursday the 6th of August morning. We’ve got 4 ft of swell from the ESE at 5 seconds, with glassy conditions (0 mph wind). The swell energy is 95 (still weak), but it’s clean and rideable. The period is short, so it’ll be a bit fat and weak, but it’s the cleanest wave in the two-week span. For a bit of a longboard cruise, that’s your moment. Don’t expect anything special, and the crowds are possible at Caerhays.
The rest of the week after that drops back into the tiny stuff. Nothing to get excited about, I’m afraid.
So, if you’re hanging for a wave, the 6th of August is the one to circle. It’s not a world-beater, but it’s the best we’ve got.

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.
