The Lowdown
Right, folks, Rusty here. Let’s be straight with you: it’s a flat spell and it’s going to be a long one. We’re looking at Caerhays for this entire 16-day window, and the truth is, there’s nothing worth paddling out for.
The whole run starts quiet and stays quiet. From Monday the 10th right through to Tuesday the 25th, every single session is marked as poor surf conditions. That’s a solid two weeks of no real wave energy. The combined energy of all swells directed here barely ever cracks a two-digit number, with most readings sitting between 8 and 30 (weak energy), and a couple jumping to 50 or 66, but even those are knee-high junk with short, choppy period.
The swell heights are tiny – 0.3 ft to 2 ft max, and the periods are all over the place. We see a bit of longer period groundswell on the 18th and 19th (16–17 seconds) but with heights of only 0.3 ft, it’s just a long-period bump, not a wave. Even the wind on those days is glassy on the 18th morning and glassy again on the 19th afternoon – a tease of clean surface but zero push.
There’s no standout option. For a few days there’s clean offshore wind, like Thursday 13th morning with a NNW 12 mph offshore breeze and a 1.0 ft WSW swell at 11 seconds, but 1.0 ft won’t lift your fins. The same goes for Saturday 15th morning – offshore N wind at 12 mph, but again 1 ft of weak energy (30). If you’re desperate, the cleanest windows are the morning of August 18th – *glassy* conditions, SSW 3 mph, with a 0.3 ft 17-second swell, or the afternoon of August 19th – glassy again, 0.3 ft swell with a 16-second period. But honestly? That’s pond scum.
Crowds won’t be an issue because nobody’s going to turn up. Caerhays is inconsistent at the best of times, and this is one of those blank stretches that makes you wonder if the tide went out and forgot to come back.
Keep your gear dry. It’ll turn eventually.
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.
