The Lowdown
Alright folks, Rusty here. Let’s have a look at what Caerhays has got cooking over the next couple of weeks.
Right off the bat, I’ve got to be straight with you – the next week and a half is a write-off. We’re looking at a solid gap from now until the morning of Monday the 12th of August where there’s basically nothing to get excited about. The swell is tiny, mostly 0.3ft to 0.7ft, and the conditions are just messy or flat. You’d be better off polishing your board than trying to get wet.
The only real glimmer of hope comes in the second week. On the morning of Monday the 12th of August, things finally start to look interesting. We’ve got a 3ft swell pushing in from the SSW with a period of 8 seconds. The combined wave energy is 108 (moderate), and the wind is a light offshore from the WNW, which is going to make for some clean, tidy lines. The water temp is about average for this time of year, so nothing shocking there.
This is the standout. It’s not a massive swell, but it’s a proper little window of clean, surfable waves at Caerhays. The wind is the key here – that light offshore breeze is going to keep things smooth. The swell is a bit short-period, but for a spot that’s inconsistent and can be a bit of a gamble, this is the best we’ve got on offer. You’ll want to get on it early Monday morning, because the afternoon sees the wind clocking onshore, turning it into a bumpy mess.
So, the long and short of it: suffer through the flat spell, then hit it hard on the morning of the 12th of August.
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.
