The Lowdown
Right, gather 'round, grab a coffee. Rusty here, lookin' over the charts for Caerhays over the next couple of weeks, and I gotta be straight with you – it's a bit of a tough stretch, if I'm honest. The swell window's just not cooperating. There's a lot of days where the ocean looks more like a lake or a washing machine than a surf break. We're talkin' a long dry spell, with barely any chance of a ride for the first week and a bit.
Water temp at Caerhays is sittin' at about 65°F, which is a touch warmer than we usually get this time of year, so at least a session won't be a full-body shiver.
The first sign of any life doesn't show up until Sunday, August 30th. Even then, it's not shoutin' from the rooftops. We've got a bit of a pulse from the SW, pushin' up around 6ft. Combined swell energy is a solid 493, so there's some weight behind it, but the period's a short, choppy 7 seconds, which means it'll be a bit of a mess. The savin' grace here is the wind, turnin' cross-off from the NNW, so the surface should be clean. It's a "marginal" call, but if you're desperate for a paddle, Sunday mornin' might just be your window. Later in the arvo, the swell drops right off.
After that, we're back to square one. Tiny, weak, wind-affected rubbish through the start of September. No standouts, no hidden gems, just a whole lot of nothin' until the very end of the forecast. There's a couple of 0.7ft bumps with some lonely long-period groundswell (15-18 seconds), but with no size and nearly no energy, you'd be fightin' an incoming tide just to get your feet wet. Honestly, for this location, it's just one of those blank runs that happens. Forecasts can change, but right now, it's lookin' pretty grim for the paddlin' crew.

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.
