The Lowdown

Alright folks, Rusty here. Let’s have a look at the Caerhays stretch over the next 16 days, and I’ll be straight with you: it’s a tough watch. The whole window is a battle against wind and chop, and we’re not getting a single decent window where the stars align.

Right now, and for the rest of the month, it’s mostly unsurfable. Friday the 28th kicks off with a tiny 2ft SSW swell at 6 seconds, but a cross-wind of 16 mph and a cross-chop has it looking like a mess. Saturday the 29th actually sees some size – 5ft on the morning, pushing 5ft in the afternoon – but the wind is howling 34 mph, cross-on, and it’s blown out. Sunday the 30th is more of the same with lumpy, cross-onshore junk.

We do get a clean-up on Monday the 31st thanks to a WNW cross-off breeze, but the swell is tiny – 2ft at best, and the energy is weak. It’s clean, sure, but it’s barely a ripple. Tuesday the 1st of September goes back to messy, and then we hit a long quiet spell. From Wednesday the 2nd right through to the 8th, the swell drops to almost nothing – 0.3ft with long periods of 12 to 16 seconds, but no push. Even with clean conditions, there’s nothing to ride.

There’s a brief flicker of life on Thursday the 4th of September, with a 5ft W swell at 8 seconds and moderate energy, but it’s crossed up with a fresh wind and lumpy. It’s a mess. The rest of the second week is a wasteland of tiny, wind-affected slop or flat calm.

To be honest, there isn’t a single standout session here. The high point is probably Monday the 31st August if you’re desperate for a clean, ankle-high dribble, but that’s not a recommendation. The wind is almost always wrong, the swell is either too small or too wind-affected, and the break is inconsistent. It’s one of those stretches where the forecast just doesn’t give us anything to work with.

I’d say hang the board up for now, keep an eye on the charts, and hope the next 16 days bring something better. This is a blank run 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.
