The Lowdown
Alright folks, Rusty here. Let’s cut straight to it. Looking at the whole 16-day window, I’ll be honest, it’s a tough one for Caerhays. The guidance tells me this spot is inconsistent and the data backs that up. We’re staring down a long stretch of flat, poor surf conditions that just doesn't let up. The first real chance of anything worth paddling out for doesn't arrive until well into the second week.
The water is sitting at a very warm 67°F, which is a massive 5°F warmer than average for this time of year. That’s a notable anomaly, but it won’t help the waves.
We kick off Thursday the 30th of July with absolutely nothing. The swell is a pathetic 0.3 ft with a combined energy of just 3. That’s like a pond. This flat, poor spell drags on through the end of July and the entire first week of August. There’s a brief moment on Monday the 3rd of August where the wind goes glassy, but the swell is still only 0.7 ft with an energy of 8. Not surfable. The pattern remains the same: tiny windswell, poor conditions, and very low energy readings. It’s a real dry spell.
The first glimmer of something different comes on Friday the 7th of August. The afternoon shows a sudden spike to an 8 ft swell from the ESE, but it’s a short-period 7 seconds and the wind is a fresh cross-onshore at 22 mph. The combined energy hits 648, which is strong, but the conditions are described as lumpy and the surf quality is poor. That’s a lot of water moving but it’s going to be a messy, blown-out wall. For most surfers, that’s a pass. The setup looks more interesting for kite surfing than paddle surfing.
Following that, the swell drops back down to nothing again. The second week from the 8th of August onward is a series of tiny, low-energy swells with poor winds. The highlight, if you can call it that, is the morning of Thursday the 13th of August. We get a 0.3 ft swell from the west with a gentle offshore wind from the NNW at 9 mph. The period is 10 seconds. It’s clean, but it’s still only 0.3 ft. The combined energy is a measly 3. By the afternoon the swell lifts to 3 ft from the ESE with a 5 second period and a cross-offshore wind, but the energy is only 54. It’s rideable for a log, but far from a standout.
Truth is, the only real standout in this entire forecast is the Friday the 7th of August afternoon pulse, but it’s only for the brave or the experts. The 8 ft wave height is well into the big stuff for beginners, and with that onshore wind, it’s a wild, messy ocean. Don’t expect any clean, lined-up waves.
For the rest of the 16 days, it’s a desert. If you’re desperate, the cleanest, smallest option is that Thursday the 13th of August morning, but you’ll be fighting for a ripple. The forecast can change, but right now, this looks like a classic blank run for the area.
Rusty.

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.
