The Lowdown

Alright folks, Rusty here. Let’s be straight with you – this forecast for the Caerhays area is a tough one. We’ve got a long, dry spell coming up.

Looking at the whole 16-day window, there’s basically nothing to get excited about. The first surf recommendation doesn’t kick in until Wednesday, the 9th of September, and even then it’s a real struggle. From that point, we’re looking at a solid stretch of days with no decent surf on offer. The models are showing a gap that runs right through until the end of the forecast on the 24th of September, with every single session rated as poor surf conditions. That’s a long, quiet run for this area.

Caerhays is the only spot in the frame, and it’s a heartbreaking one. It’s inconsistent here, and this forecast proves it. The first few days are a write-off. On Wednesday morning the 9th, we’ve got a tiny 1ft SW swell with a weak 8-second period and low energy (25). The wind is a cross-off from the NW at 12 mph, which keeps it clean, but there’s just no push. The afternoon bumps up to 3ft from the WSW, but the energy is still rubbish (117) and it’s the same story. The water temperature is about average for the time of year, nothing to write home about.

Thursday the 10th is a complete mess. Onshore winds from the SSW pick up to 16-22 mph, and the swell is a pathetic 0.7ft to 3ft with a period that drops to just 4 seconds – that’s pure wind chop. It’s choppy and lumpy, not worth paddling out for.

The pattern continues: Friday the 11th through Tuesday the 15th offers tiny, weak swells with poor wind directions. The energy is almost non-existent, with values like 13, 12, and 6. The wind is mostly cross-on or cross-off, but the swell is just too small to do anything with. There’s a 3ft ESE swell on the 20th and 21st of September, but the period is a short 4-5 seconds and the wind is cross or cross-on, making it a messy, weak affair.

The long-range stuff, from the 22nd to the 24th of September, is no better. The wind is a strong, fresh cross-shore from the east at 19-22 mph, and the swell is tiny – 0.3ft to 0.7ft. Even when the swell period gets up to 17 seconds on the 22nd, it’s for a 0.3ft swell, which is nothing. The energy is in the low 20s and teens. The offshore wind on the 18th and 19th is a tease, but the swell is a miserable 0.3ft to 0.7ft.

Honestly, there’s no standout here. Nothing. The best on offer, and I use that term loosely, would be the Wednesday morning the 9th of September. The wind is clean, cross-off from the NW, but with a 1ft, 8-second swell and 25 energy, you’re looking at a micro-session on a longboard, at best. It’s not a recommendation, it’s a desperation move. For the rest of the period, the setup is so poor with weak, short-period swell and onshore or strong cross-shore winds, that it looks more interesting for kite surfing than paddle surfing. But even then, there’s no wind strength for that either.

It’s a blank run. That’s the reality of it for this area. Forecasts can change, but for now, leave the boards at home.

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.
