The Lowdown
Alright folks, Rusty here, and I’ve got to level with you – this 16-day outlook for Caerhays is a total bust. The first report kicks off on Sunday, July 19th, and from there, it’s all downhill. The water is running at 68°F, which is a staggering 6°F warmer than the norm for this time of year – that’s very unusual, and about the only thing that’s worth noting.
From that Sunday afternoon, we’re looking at a tiny 0.3ft swell out of the south with a 19-second period. That’s a long period, sure, but with next to no energy (combined energy is just 18), it’s dead flat. The wind is a light cross-onshore, and the whole thing is flagged as “poor surf conditions.” Monday morning isn’t any better – a cross-shore chop with 12 mph winds, and Monday afternoon goes glassy but still holds that pathetic 0.3ft swell. Tuesday, Wednesday, Thursday, Friday… it’s rinse and repeat. Swell heights never get above 0.7ft, and the combined energy rarely breaks 10 – it’s about as weak as it gets.
Around Thursday, July 23rd, we see a tiny bump in energy to 16, but it’s still a 0.3ft southwest swell with a cross-shore wind. The wind does go offshore a few times – like Wednesday morning, July 22nd, with a 9 mph north wind, and Wednesday afternoon with a 19 mph north-northwest, which would be clean – but there’s simply no swell to push. You’d be staring at a flat ocean. Even the glassy, calm conditions on Friday, July 24th, and Saturday, July 25th, with offshore winds, can’t make something out of nothing.
The second week offers no relief. From July 27th through to August 3rd, it’s the same sad story. A few days show a 0.7ft swell, like Monday morning, July 27th, and Tuesday afternoon, July 28th, but the energy is still pitiful (6 and 8, respectively). The wind does clean up regularly – plenty of offshore and cross-offshore breezes – but with swell that small, it’s a complete washout. The longest gap of no surf potential is the entire 16 days, so you’re looking at a solid two weeks of nothing.
For a spot like Caerhays, which is fairly exposed to the swell, this is a rough patch. But given that it’s listed as “inconsistent” anyway, a dry spell like this isn’t totally unexpected. If you’re itching to get wet, keep an eye on it, but I wouldn’t plan a trip. Forecasts can change, but right now, I’d find another hobby.
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.
