The Lowdown
Alright folks, Rusty here. Gonna level with you straight up: looking at the Caerhays forecast for the next 16 days, and it’s a tough one. There’s nothing that really gets the heart pumping. The whole window is a flat spell, almost like the ocean’s gone on holiday.
We start off on Thursday the 30th of July with pretty much nothing – a tiny 0.3ft swell coming from the S, but it’s got a long 13-second period. The energy is weak, only a 3 in the water. The wind is going to mess it up anyway. Friday and Saturday are more of the same; flat, messy. It’s not until Monday the 3rd of August we see a whisper of hope with a glassy 0.7ft wave in the morning. But it’s still a "poor surf" situation, and the combined swell energy is only 8. You’d be lucky to get a knee-high dribble.
By Tuesday the 4th and Wednesday the 5th, we’re still in the doldrums. The biggest we see is a 1ft swell on Monday afternoon, but it’s short period (5 seconds) and weak. For a break that’s fairly exposed to a SSW swell, the direction is all over the place. The biggest bump in the whole outlook is around Thursday the 6th of August, where we see a 3ft swell from the ESE, with energy creeping up to 40 and 38. But it’s still marked as poor surf, and the wind switches around to an onshore, which will make it a choppy mess. Even the 3ft on the 8th of August, with the wind holding clean from the ENE, is just too weak and poorly directed to make anything of. The period is a short 7 seconds. You could probably get a little close-out shorebreak, but it’s not surfing.
The truth is, for the entire 16-day run, there isn’t a single standout. Not one. The swell heights are consistently below 3ft, the energy is weak (mostly two-digit figures under 100), and the wind, while sometimes clean, can’t create a wave out of nothing. If you’re a kitesurfer, there might be some grunty wind days, like the fresh 18-22 mph breezes on the 8th and 9th of August, but for a paddle surfer, you’re better off finding a river or a skatepark.
We’ve got a solid two-week gap of nothing. It’s a blank run, but that’s the reality of this spot when the Atlantic shuts off. The forecasts can change, so don’t lose all hope, but right now, there’s no reason to rush down there.
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.
