The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer for Caerhays over the next couple of weeks.

To be straight with you, it’s a pretty grim outlook. The whole 16-day window is basically a bust for any meaningful surf. The combined energy of all swells directed here barely breaks double figures, with values mostly in the single digits (15, 3, 32, etc.), and the swell heights are tiny. We’re looking at a long stretch of flat to near-flat conditions, with almost every session being written off as poor surf. The water is sitting at 66°F for the first mention, which is a whopping 5°F warmer than usual for this time of year – that’s very unusual, but it won’t do you any good with no waves.

The first real standout? There isn’t one. The best we see is a very small bump on the morning of Sunday, July 19th, with a 3ft swell from the ESE, but it’s got a short period of 5 seconds and a cross-shore wind of 16 mph from the E. That’s just messy. The afternoon of that same day gets glassy with a 2ft SE swell, but again, period is only 5 seconds and the energy is weak (35). It’s barely rideable for a log.

After that, we’re back to nothing. There are days and days of 0.3ft swell or less. The wind does go offshore quite a bit – you’ll see a clean, offshore breeze from the NNW on the 22nd, 23rd, and 24th, and even a glassy moment on the 20th and 21st. But with no swell to push, it’s just a flat, clean ocean. The setup is a fairly exposed beach, so it’s not like a river mouth or reef that might pick up a stray pulse. This is just a blank run.

For the second week, from the 25th of July right through to the 1st of August, it’s the same story. A few more offshore days, but the swell heights are laughable – 0.3ft to 2ft at best, with weak energy (9, 12, 14). The standout non-event would be the morning of Monday the 27th, with a 2ft W swell and a 3-second period, blown out by a 16 mph cross-offshore wind. That’s less surf, more wind chop.

Honestly, this is a classic case of no good surf options in the whole 16-day window. The forecasts can change, but for now, leave the boards at home.

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.
