The Lowdown

Alright folks, Rusty here with a look at the waves.

To be straight with you, this stretch is looking pretty grim. We’ve got a solid 16-day window, but don’t hold your breath for anything worth paddling out for. There’s a massive gap right from the start with absolutely nothing to recommend for the first couple of weeks. The swell is tiny, the wind is messy, and the energy is just not there.

For nineteen days straight, from September 8th through to the morning of September 23rd, it’s a total write-off. We’re talking about ankle-snatchers at best, with periods of stiff cross-off winds and cross-onshore chop. The combined energy readings are almost all in the gutter, with values like 55, 26, or even down to single digits (2 to 55). It’s a classic dry spell for the area, and it’s normal to see this kind of blank run. When there’s nothing to ride, forecasts can change, but for now, it’s a surfers’ desert.

The only faint glimmer comes right at the tail end of the outlook. On Wednesday, September 23rd, we finally see a pulse of something. The morning session at Caerhays will have a 1.0 ft SSW groundswell with a very long period of 16 seconds. That long period gives it some shape potential, and with moderate offshore winds from the NNE at 12 mph, it’ll be clean. The combined energy is moderate at 57. It’s small, but it’s the only game in town. The water temp is a touch warmer than normal, coming in at 64°F. This is not a session for beginners, though – the small size is okay, but the long period can make it feel a bit tricky on the inside. The crowds can pop up sometimes, so you might have a few others with the same idea. For the afternoon, it drops back down to 1.0 ft with a 15-second period and moderate offshore wind, but the score is a flat zero, so the quality fades fast.

That’s it. A long, dry wait for one brief window of clean but tiny waves.

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.
