The Lowdown
Alright folks, Rusty here. Let's break it down. It’s looking pretty grim for Caerhays over the next two weeks, I won't sugarcoat it. The charts are mostly showing a flat spell, and when a little bump does show up, the wind's all wrong.
The first real chance of anything is a solid week away. The water's a touch warmer than normal for this time of year, running at 64°, but that's about the only positive note right now.
We’ve got a long dry spell to start. Thursday the 10th kicks off with a tiny 3ft SSW swell, but it's short period at 4 seconds, and a fresh cross-onshore wind at 19 mph is shredding it. The energy is weak at 34. It's a mess. Friday the 11th goes even smaller. The wind swings NW and the ocean turns clean, but wave heights drop to a pathetic 1ft. There's a 10-second period, but you'd be hard pressed to find a ride.
This pattern of tiny, wind-affected surf or clean flat spells holds through the weekend and all of next week. We get some clean windows on the 15th, 16th, and 19th, but with waves sitting at 0.3ft to 1ft, there's just nothing to surf. The energy readings are mostly in the single digits or low teens. It's tough.
The only standout, and you have to wait for it, is Caerhays itself. Looking all the way to Wednesday the 23rd, we finally see a pulse of energy. The afternoon brings a 5ft swell from the SW. The period is short at 6 seconds, so it'll be a bit weak and crumbly, but the combined energy reading jumps to a moderate 164. The wind is a light cross-onshore from the ESE at 6 mph, so it'll be bumpy, but it's a huge improvement over the 19 mph breezes we've been seeing. It's the best on offer in the whole 16-day window.
Before that, Thursday the 24th morning shows a 1ft swell with a very long 13-second period from the WSW, and energy at 37. That long period means good shape, but with onshore wind, it'll just be a lumpy closeout.
We’re looking at a full week of nothing until that slight uptick on the 23rd. Given the lack of consistent swell, a blank run like this is pretty normal for the area. Don't get your hopes up too high, but keep an eye on the 23rd. 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.
