The Lowdown

Alright folks, Rusty here. Let's talk about the Caerhays forecast for the next couple of weeks. To be honest, it’s a pretty grim stretch we’re looking at, so don’t go getting your hopes up for any kind of quality waves right now.

Right off the bat, if you're looking for a proper surf, you’ll be waiting a long time. The first recommendation for a surfable wave doesn't show up until Sunday, the 16th of August, and even that is just barely making the cut. That’s nearly two weeks of flat, tiny, or junk conditions. The water is sitting at 66°F, which is a touch warmer than normal for this time of year, but that’s not going to help the waves do anything.

For that first little blip on Sunday the 16th afternoon, we’re looking at a tiny 3ft SSW swell. It’s clean with a cross-off breeze, but the wave energy is weak at only (60). It’s small, it’s ordinary, and it’s more of a paddle than a ride.

The only real standout in this entire 16-day window is Monday the 17th. On Monday morning, Caerhays picks up a 3ft SW swell with a moderate offshore NNE wind at 15 mph. The conditions should be clean and the combined energy hits a moderate (110) – finally something with a bit of kick. It’s not big, but that clean, offshore wind will make it smooth. Just a heads up, it can get a bit busy here sometimes. After lunch, the wind goes glassy with light NW airs and a 3ft SSW swell. Monday is your best bet if you’re desperate for a surfable wave, but don’t expect perfection.

After that, Tuesday the 18th morning has a clean 2ft SW swell with light offshore winds, but that same afternoon the wind cranks up to 19 mph, making it messy. Wednesday the 19th morning is glassy again with a 2ft WSW swell that has a decent 11-second period, but it’s still just ankle-biters.

So there you have it. A big long gap of nothing, then a couple of days right at the back end of the outlook that look half-decent, with Monday the 17th being the clear high point. Keep an eye on it, but don’t hold your breath.

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.
