The Lowdown

Alright folks, Rusty here. Let’s talk about what’s happening at Caerhays. I’ll be straight with you – this is a tough one. The entire 16-day window is a real struggle, with no decent surf to speak of. The first recommendation doesn’t even pop up until Wednesday, August 12th, and even then it’s a no-go. We’re looking at a long, dry spell with barely a ripple.

The water temp is sitting at 66°, which is a touch warmer than normal for this time of year. That’s a small comfort, but it doesn’t help with the waves.

On Wednesday the 12th, we’ve got a tiny 3 ft swell from the ESE, but with a shockingly short period of just 4 seconds. The wind is a fresh cross-shore, making it lumpy and messy. The combined energy is a weak 39, so there’s just nothing to work with. Thursday the 13th sees the swell drop to 1 ft, and while the wind turns clean with a cross-off, the wave energy is pitiful at 29. Friday is even smaller at 0.7 ft. Saturday and Sunday have offshore winds, but the swell is basically non-existent at 0.7 ft or 0.3 ft. The pattern repeats all the way through to the end of the month – tiny, weak swells, often with poor wind, and a whole lot of nothing.

The only thing that might raise an eyebrow is Monday the 24th, when we get a 2 ft swell from the south with a 4-second period, and the wind is light and clean. But it’s still tiny, with a combined energy of 27, and it’s accompanied by rain showers. There’s no standout here, no day to get excited about.

This is a classic case of an inconsistent spot living up to its name. For the entire 16 days, every single entry is marked as “poor surf conditions.” If you’ve got a kite, the wind on some days might be interesting, but for a surfboard, you’re better off waiting for a change in the forecast. The energy is weak across the board, with the highest combined energy value being just 39. It’s a blank run, plain and simple.

Keep your eyes on the charts, but for now, I’d say find something else to do.

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.
