The Lowdown

Alright, let’s get real about the surf for Caerhays over the next 16 days.

To be straight with you, it’s a rough stretch. We’re looking at a solid run of poor conditions, with very little to get excited about. The first few days are a write-off, and honestly, it’s a long, slow grind before we even see a hint of a wave worth paddling for.

The first recommendation isn’t until Monday, September 7th, so we’re looking at a gap of over a week with nothing to offer. That’s a tough pill to swallow.

Caerhays (Caerhays) is the only game in town, and it's an inconsistent spot that’s rarely firing. It’s a fairly exposed break, but it needs a solid SSW swell and clean winds to work.

On Saturday, August 29th, it’s a no-go. We’ve got a 5ft swell from the SSW, but the wind is a strong cross-onshore, making it lumpy and messy. The water is a touch warmer than normal at 65°, but that’s the only good news. The combined energy is moderate (198) on Saturday morning, but it’s not doing us any favours.

Sunday the 30th is more of the same – small, onshore, and poor. The swell drops to 3ft with a short period of 7 seconds, and the energy is weak (75). Not worth a look.

Monday the 31st offers a glimmer of hope. The swell is tiny at 2ft, but the wind goes cross-offshore from the WNW, and conditions are clean. The combined energy is weak (108), but it’s the cleanest we’ve seen. It’s a beginner-only wave at best, and even then, it’s inconsistent.

The rest of the first week and into the second is a real struggle. Small, short-period slop with onshore winds. The best chance for a decent paddle comes on Monday, September 7th. The swell is still small at 1ft, but the wind goes glassy from the S. Combined energy is weak (69), but the glassy conditions mean it’s the most surfable we’ll see. It’s still a very ordinary wave, but if you’re desperate, that’s your window.

Thursday, September 10th, could be interesting for the wrong reasons. The swell picks up to 4ft from the SSW, with a short period (6 seconds) and a moderate onshore wind. The combined energy is moderate (114). It’s going to be choppy and messy, and the setup at Caerhays is a beach. Honestly, with that wind and swell, it might be more interesting for a kite surfer than a paddle surfer.

Friday, September 11th, is a strange one. A 1ft swell from the WSW with a long period of 14 seconds, and light onshore winds. The combined energy is moderate (129). That long period means the wave will have some shape, but it’s going to be very small and inconsistent. It’s a point break or reef kind of day, not a beach break.

Saturday, September 12th, and Sunday, September 13th are back to tiny, weak swells. The morning of the 13th is glassy, but the swell is only 1.0ft with a 10-second period and weak energy (32). It’s a flat, glassy day.

The bottom line: There are no standouts. The best of a bad bunch is Monday, September 7th, for the glassy conditions, and maybe Friday, September 11th, for the long-period swell, but it’s tiny. Don’t get your hopes up. This is a long, quiet stretch for Caerhays.

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.
