The Lowdown
Right then, let’s have a look at what’s on the cards for Caerhays.
To be straight with you, mate, this is a tough outlook. Over the next 16 days, there simply isn’t a single session that offers decent surf. The wave energy is very low, barely registering a pulse, and what little swell that shows up is weak and messy. We’re looking at a real dry spell here.
Let’s break it down. From the start on Sunday the 2nd of August right through until Friday the 14th of August, it’s basically flat or ankle-high dribble. Swell heights are stuck between 0.3 ft and 0.7 ft, with periods hanging around 4 to 8 seconds—that’s pure windswash, nothing with any push. Wind is all over the place, but mostly onshore or cross-shore, ruining even that tiny bit of shape. The combined energy readings are in the single digits or low double digits (3 to 36), which is just a whisper in the water. You might see a clean morning here and there, like the 7th of August with glassy conditions, but with only 0.3 ft of swell, it’s not worth paddling out for.
A bit of a lift shows up on Saturday the 15th of August. The swell bumps up to 4 ft in the morning and 5 ft in the afternoon, coming from the ESE with a period of 5–7 seconds. The combined energy hits 96 and then 223 (moderate wave energy) on the Saturday arvo, so there’s finally some water moving. But the wind is onshore from the WSW and SW, pushing that swell straight into chop. It’s going to be lumpy and messy—not the clean lines we’d want. That trend continues into Sunday the 16th of August, with a poor 5 ft swell from the ESE (period 8 seconds) and onshore wind up to 19 mph, giving a combined energy of 274. Monday the 17th sees the biggest swell of the whole run, at 6 ft from the ESE, but again the wind is cross-on from the SW at 9 mph, and with a short period of just 6 seconds and combined energy of 291, it’s going to be a roped-up, onshore mess. At that size and with those conditions, it’s really more of a kitesurfer’s or windsurfer’s setup than a paddler’s wave.
Caerhays itself is a fairly exposed break that handles a SSW swell best, but we’re not seeing that direction in any meaningful way. It’s also listed as inconsistent, which fits the pattern here. Honestly, this is a blank run that’s pretty normal for the area when conditions align like this—just nothing to get excited about. Hang in there, forecasts can change.

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.
Caerhays is 13 km (8 miles) from Saint Austell. If you plan a holiday in South Cornwall, look for hotels and other accommodation in Saint Austell. Saint Austell has rooms for a wide range of budgets as well as car hire and transport links.
