The Lowdown
Right then, ol’ mate. I’m Rusty, and I’ve been staring at this chart for Caerhays for a while now. Gotta be honest with you, it’s not looking like a classic. The whole 16-day run is a bit of a flat spell, to be brutally frank. You’re looking at a stretch with no real standouts, and the first bit of the week is basically a write-off. We’re talking about a whole lot of days with barely a ripple.
The first real sniff of anything that might be worth a splash isn’t until the morning of the 5th, and even then, it’s small. The water here is sitting at 64°, which is a touch warmer than normal for this time of year, so at least it’s not freezing.
The first few days are a real struggle. From Tuesday the 1st right through the week, it’s all small, onshore chop. The wind is mostly cross-on from the SW or WSW, kicking up wind ripples and generally making a mess of things. Swell heights are barely scraping 2 ft to 3 ft, with periods as short as 3 seconds, and the combined energy is a weak 12 to 51 (weak). Truth is, it’s poor surf conditions across the board.
Saturday the 5th morning is a weird one. The wind goes glassy from the NE at just 3 mph, but the swell is barely a whisper at 0.3 ft with a long 14-second period. The combined energy is a measly 15 (weak). It’s clean, sure, but that’s about it. Not much to ride. The afternoon goes onshore again.
The rest of the first week, from the 6th to the 9th, is more of the same: small, onshore, poor conditions. The wind swings around a bit, but it’s always messy. Swell heights are still under 3 ft, and the combined energy is weak, usually under 50 (weak). A few mornings on the 7th and 9th show clean cross-off winds, but the swell is still tiny (1 ft or 0.7 ft), so it’s just a clean, empty ocean.
The second week is even more of a snooze-fest. From the 10th of September onwards, the swell drops to 0.7 ft or 0.3 ft. The combined energy is a pathetic 3 to 15 (weak). The winds are clean, often cross-off or offshore, but with no swell to speak of, it’s just a flat glassy lake. There’s a tiny bump on the 13th with a 0.3 ft, 14-second swell from the W and a clean offshore wind from the NNW, but it’s nothing to get excited about.
So, the bottom line: there’s no standout session here. The entire 16-day window is a flat, small, and often choppy period. The best you can hope for is a clean, small wave on the 5th or maybe a session on the 7th if you’re desperate for a knee-high glide. But honestly, for a proper wave, you’re better off waiting for a change in the weather pattern. This is a good time to work on the board or go for a paddle.
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.
