The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for the next couple of weeks.
Honestly, this is a tough stretch to be a surfer around here. We're looking at a long, quiet period with hardly anything worth paddling out for. The first real sniff of anything rideable doesn't show up until late in the game.
For the whole first week and beyond, it's mostly tiny, weak swell with messy winds. We've got a few days with clean conditions, but the energy is just not there. The best of a bad lot looks like it might be Sunday the 27th of September, but even then, it's pretty ordinary.
The only break on the radar is Caerhays. The first time we see any surfable waves at all is on the 27th of September, but it's a very average offering. The combined wave energy is weak (61-87), with a swell around 1 ft to 1 ft. It's coming from the WSW and SW, not ideal for this break’s preferred SSW direction. The water is a touch warmer than normal for the time of year at 64°F on the 15th, but you won't be in it much anyway. The conditions are clean on that Sunday with a light northwest breeze, but the waves are just too small and weak to get excited about. This spot is normally inconsistent, so a run of flat days isn't that unusual.
To be blunt, if you're looking for a wave here, you're looking at a two-week wait for very average, knee-high slop. It’s a bleak outlook. If the wind cranks up and the swell stays this small, the beach might be more interesting for a kite surfer than a paddle surfer, but even that’s a stretch. The forecast can change, but as it stands, leave the board in the car.

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.
