The Lowdown
Right then, folks. Rusty here. Let’s have a look at what’s on the cards for the next couple of weeks. To be straight with you, it’s a quiet stretch. There’s no surf worth mentioning for a good long while, so we’re looking at a gap of several days with nothing on offer. The water temperature is about 66°, which is a touch warmer than normal for this time of year.
We start with Caerhays – the only spot on the list, and it’s inconsistent. It’s a fairly exposed break, so it needs a proper push from the right direction, which is SSW. The first real sign of anything happening doesn't come until Monday the 12th of August, and even then it’s tiny. Wednesday the 14th of August morning has a glimmer with a small 0.3ft swell from the WSW, with an 11-second period (28 combined energy). It’s clean with a gentle offshore, but it’s still barely a ripple. Nothing else in that first week has the size or the quality to get excited about. The wind is often cross or cross-off, keeping things a bit messy or just plain flat.
The second week doesn’t offer much more. There’s a little bump of energy around Monday the 19th of August morning, with glassy conditions and a 0.7ft, 8-second WSW swell (13 combined energy), but it's just too small to be a proper surf. There’s a small window on Thursday the 22nd of August morning with a 0.3ft, 16-second period swell from the SW (12 combined energy) and a fresh cross-off wind, but the size is the killer. The period is long, so it’d be straight and weak on the beach.
Honestly, there’s no standout here. No one day delivers enough size, good wind, and any sort of consistency. If you're desperate for a paddle in flat, glassy conditions, you might find a moment on Monday the 19th, but you won't be catching waves. For any real surf, you’d need to look elsewhere or wait for the forecasts to change. It’s a blank run, and for this area, that’s pretty normal.
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.
