The Lowdown
Alright folks, Rusty here. Let’s be straight with you: this sixteen-day stretch for Caerhays is a tough one. We’ve got a long, bleak gap to start with. The first real mention comes on the 25th of August, but even then, it’s a no-go. Honestly, it’s looking like a bit of a write-off for a while.
Starting Tuesday afternoon the 25th, we see a weak 4ft swell from the ESE with a short period of 5 seconds. The combined energy is a measly 74, just weak stuff. To make matters worse, the wind is a cross-shore breeze at 16 mph, creating a cross-chop. It’s just poor conditions. The water’s a touch warmer than normal at 64°, but that’s little comfort when the surf is this messy.
The outlook doesn’t improve for the rest of the week or into the weekend. We get a sniff of a slightly larger swell on Saturday the 29th of August, with 5ft to 5ft from the SSW, and the energy jumps to a moderate 197-247. But the wind is howling onshore at 22-28 mph from the SW and WSW. It’s fresh to strong breeze, making the ocean lumpy and messy. That setup is more interesting for kite surfing than paddle surfing, to be honest.
Sunday the 30th and Monday the 31st stay small and choppy, though Monday morning gives us a brief window of clean conditions with a light cross-offshore breeze from the NW. But the swell is only 2ft, so there’s not much to ride.
We then hit another long gap. From Tuesday the 1st of September right through to Sunday the 6th, the surf is virtually non-existent. Swell heights stay below 3ft, with periods as short as 4 seconds and weak energy figures in the teens. The wind is onshore or cross-onshore most of the time. There’s a notable moment on Sunday the 6th of September morning when the wind goes glassy from the SSE, and a long-period groundswell of 13 seconds tries to push in at 0.3ft. But that’s a whisper, not a wave.
We do see one glimmer far out. On Monday the 7th of September, the swell picks up to 4ft from the SSW, and the combined energy hits 183 on the afternoon. However, that’s paired with a strong cross-onshore wind at 25 mph from the SW, making it a messy, expert-only proposition if it gets clean anywhere.
The outlook then drifts back into small, choppy conditions through to the end of the window. This is a classic blank run for the area, and it tends not to stay this poor for long, but for now, there’s just no standout session to get excited about.
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.
