The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the cards for Caerhays. I’ll be straight with you – this forecast is a tough one to swallow for a surfer.
For the next week and a half, the surf is pretty much a no-show. We’re looking at a long, drawn-out stretch of flat or near-flat conditions, with only tiny dribbles of swell. The first real glimmer of something surfable doesn’t pop up until Friday the 14th of August, and even then, it’s nothing to write home about.
The Big Picture
Overall, the wave energy is very weak. The combined swell energy rarely gets into double figures, and for most of the period it’s sitting in the single digits (e.g., 8, 4, 6) – that’s about as weak as it gets. The water temperature is a touch warmer than normal for this time of year, sitting at 66°.
The Long, Dry Spell (Now – 13th August)
From now right through to the 13th, it’s a write-off. We’re talking swell heights of barely 0.7ft to 1ft, with periods that are mostly short or, when they do get long (15 seconds on the 7th), the swell is just too tiny to do anything with. Winds are a mixed bag, but it doesn’t matter when there’s no waves. Don’t bother paddling out. This is a proper flat spell.
The One Day That Might Just Offer Something
Friday the 14th of August – this is your best bet, and it’s the only one I can point you towards. The morning session is the pick. We’ve got a small pulse of swell coming in from the W at 2ft, with a period of 8 seconds. The combined energy jumps to 60 – still weak, but a massive improvement on what we’ve seen. More importantly, the wind is glassy out of the NNW. That means absolutely clean conditions, which is a major positive for a break like this.
Caerhays is a fairly exposed spot, and it’s inconsistent, but with glassy wind, those tiny waves will look a lot better than they have any right to. The swell direction is from the W, which is not quite the optimum SSW, but the glassy wind makes up for a lot. The afternoon sees a cross-off wind, which is still workable, but the swell drops back to 2ft.
After the 14th, it’s back to tiny, poor conditions right through the rest of the forecast window. The 17th of August has a moment of absolute glass (0 mph wind from the W) with 1ft swell, but the energy is still weak (25). It’s a tease.
So there you have it. It’s going to be a lean couple of weeks. The 14th is the standout – a rare morning of glass and a tiny bump. If you’ve got a log and you’re desperate, that’s your window. Otherwise, it’s a good time to wax your board and wait.
Stay keen,
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.
