The Lowdown

Alright folks, Rusty here, and I’ve got to be straight with you. The Caerhays region is looking at a pretty quiet stretch ahead. The overall pattern for the next couple of weeks is mostly small, weak surf and a fair bit of wind, leaving the ocean mostly flat and messy. It’s not going to be easy to find anything worth paddling out for, so we’ll be waiting for any real windows.

Looking at the start, the first real potential pops up on Thursday, 27 August. There’s a bit of a lift with a 4 ft SSW swell rolling in for the morning, but the wind is a cross-onshore from the SW at 12 mph, making it choppy. Not great, not terrible, but the combined wave energy is only moderate at 122. The SSW swell matches the optimum direction for Caerhays, but with the onshore wind and a short period of 6 seconds, the quality just isn't there for a standout.

The best bet in this whole run, and I mean the one true standout, looks like it could be Wednesday afternoon, 9 September. We’ve got a 5 ft swell from the S with a moderate breeze from the WNW at 16 mph, giving us a clean, cross-off wind. The combined energy here jumps to a strong 220, which is the most juice we see in the whole forecast. The swell period is still short at 6 seconds, so it’ll be a bit crumbly, but clean conditions will make it the best session on offer. Keep in mind this is a long-range call, so don’t book the week off just yet.

There's a big dry spell between the end of August and that standout. From Friday, 28 August, right through to Tuesday, 8 September, the surf is tiny, blown out, or both. Most days have a combined energy well under 100, with winds mostly onshore or cross-shore. Expect long, flat stretches with no real recommendations. Before that, the water temp is sitting around 64°, which is a touch warmer than normal for this time of year, so a wetsuit might be a little unnecessary.

Given the combination of significant swell, poor surf quality, and strong winds on some of the bigger days (like the 5 ft swell on Tuesday afternoon, 1 September with a 22 mph cross-on), this setup looks far more interesting for kite surfing than paddle surfing. For the rest of us, patience is key. It tends not to stay poor for long here, and forecasts can change.

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.
