The Lowdown
Right then, let’s have a look at what’s on the cards for the next couple of weeks. I’ll be honest with you, it’s a bit of a tough one to call. The forecast is showing a real lack of any proper swell energy for the entire sixteen-day period, so we’re looking at a long stretch of tiny, poor surf.
The first real chance at anything even resembling a wave comes right at the start, on Saturday, the 1st of August. We’re talking about a tiny 0.3ft lump from the west with a period of 10 seconds. The combined energy is a measly (2), so it’s barely a ripple. The wind is light and glassy in the morning though, which is about the only saving grace. But with that sort of height, it’s not really a surfer’s wave. The afternoon turns a bit cross-off, but still, it’s flat.
Sunday the 2nd and Monday the 3rd are more of the same. The swell tries to swing a little more south-west, but it’s still only 0.3ft to 0.7ft. Monday morning does go glassy with the wind, and the combined energy nudges up to (7), which is still weak. You’d be hard-pressed to get a ride on a log.
From Tuesday the 4th through to Sunday the 16th, the pattern is pretty grim. The swell height never gets above 3ft, and even that is on Wednesday the 5th with a period of just 7 seconds and a cross-shore wind from the west at 18 mph. The combined energy that day hits (79), which is the highest we see, but it’s still weak and the wind is messing it up. The rest of the time it’s a mix of onshore winds, cross-off breezes, and minuscule swell. The longest period we see is a 20-second swell on the 16th, but it’s a tiny 0.3ft, so it’s just a long-period bump on the tide line.
Honestly, for the whole sixteen days, every single entry is marked as “poor surf conditions”. There’s no standout session, no window of quality. The break at Caerhays is inconsistent at the best of times, and this run is a blank one. The water temperature is about average for the time of year, but that doesn’t really help when there’s nothing to ride. This is one of those periods where the forecast can change, but right now, it’s a long wait. Keep your eye on it, but don’t hold your breath.

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.
