The Lowdown

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

Honestly, mate, it’s a grim stretch. The whole 16-day window is a write-off for any decent surf. We’ve got tiny, weak waves and generally wonky winds, and the forecast is screaming “poor surf conditions” from start to finish. There’s a massive gap right from the get-go with nothing worth paddling out for. The first week is the worst of it, with barely a ripple.

Monday the 10th kicks things off with a tiny 1 ft SW swell at 6 seconds – that’s barely a bump. The wind is cross-off, but the combined wave energy is a feeble 10 (weak energy), so it’s just not doing anything. The water is 66°, which is a touch warmer than normal for this time of year. That’s about the only highlight.

Tuesday and Wednesday are even worse, with the swell staying under 3 ft, short period, and cross-shore winds that are chopping it up. The energy values are still in the weak range, maxing out at 41 on Wednesday afternoon. It’s not surfable, plain and simple.

Things get a little cleaner from Thursday onwards, with some cross-off and even offshore winds, but the swell is so small – 1 ft or less – that it’s pointless. Saturday the 15th has a bit of offshore wind, but the swell is 0.7 ft with a combined energy of just 6. You’d be sitting on a board doing nothing.

The second week (from the 17th onward) doesn’t get any better. We see some longer period swell (15-18 seconds) sneaking in from the south, but the height is still a pathetic 0.3 ft. That long period might sound good, but with zero size, it’s a non-event. The energy values are all in the single digits or low teens. The only thing that changes is the wind, but it’s often cross or cross-on, and by the 21st, it’s a fresh cross-shore with a lumpy chop – not for surfing.

The final couple of days, the 22nd and 23rd, show a tiny blip. On Saturday the 22nd, the afternoon goes glassy with a 3 ft SSW swell, but the period is only 4 seconds and the combined energy is just 37. That’s weak, mushy, and poor. The 23rd has a 2 ft WSW swell with a 10-second period and a bit more energy (81), but it’s still under 3 ft and the wind is a fresh cross-off. It’s clean, but there’s nothing to ride.

Forget about a standout. There isn’t one. This is a classic blank run for this area – when it’s flat, it’s flat, and the forecasts can only improve from here. For now, it’s a solid no-go for any paddle surfing. If you’re desperate for a session, maybe a kite could get some use out of the breezier days, but for a surfer, keep the board in the car.

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.
