The Lowdown

Alright folks, Rusty here. Let's break down what Caerhays is serving up for the next couple of weeks.

Right off the bat, I gotta be honest: this stretch is lookin' pretty dead. The water's a touch warmer than normal for this time of year, about 66°, but that's the only thing with any pulse.

We start on Friday the 7th of August with tiny little 0.3ft waves out of the south. The morning is glassy, but there's zero energy in the water, a combined swell energy of just (8). It's a poor surf call. And that's the story for the whole first week. Saturday and Sunday stay flat and weak, with the wind getting a bit messy Saturday before cleaning up for a glassy Sunday morning, but again, the swell just ain't there.

Through Monday and Tuesday, the swell tries to bump up a little. Tuesday afternoon the 11th sees the swell climb to about 3ft from the ESE, but the period is a pathetic 4 seconds – that's just wind slop. Plus, the wind is a fresh 30 km/h cross-shore, making it lumpy and ugly. Not one for the paddle. By Wednesday morning the 12th, we finally see some energy kickin' in – 141 – with a 5ft ESE swell, but again, that wind is howlin' cross-shore at 30 km/h, creating a nasty, choppy mess. That’s the biggest swell of the whole forecast, but it's unsurfable for a paddle. If you're on a kite, that Wednesday morning might look a bit more interesting, but for a surfboard, it's a hard pass.

After that, it all just fades away. The rest of the week and into the second week is just tiny dribbles, 0.3ft or 0.7ft, with the occasional glassy or offshore window, but nothing with any power behind it. There's a big gap of days with nothing worth paddling out for.

Honestly, there is no standout here. There’s no best on offer. If you absolutely have to get wet, the cleanest conditions will be on the glassy mornings, like Friday the 7th or Monday the 10th, but you'll be fighting for a ripple. It’s a quiet, flat spell for Caerhays.

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.
