The Lowdown

Alright folks, Rusty here. Let’s be straight with you: it’s a lean stretch ahead for Caerhays. The whole 16-day window looks pretty grim, so don’t be holding your breath for anything special.

We kick off Thursday the 27th of August with a tiny 2 ft swell from the SSW, but it’s blown out with onshore winds and the combined wave energy is weak at just 52. Water temp’s sitting at 64°, which feels a touch warmer than normal for this time of year, but that’s the only good news. Friday gets a bit more size, up to 4 ft from the SW by the afternoon, but that’s with a fresh cross-shore wind and lumpy chop—surf quality is shot. Saturday the 29th sees the biggest pulse, with swell hitting 4 ft to 5 ft from the SSW and moderate wave energy (137 to 335), but strong winds make a mess of it. By Saturday afternoon, the energy jumps to a moderate 335, but with a strong cross-shore breeze and messy conditions, this is more of a kite-surfing show than a paddle session.

Sunday the 30th drops back to 4 ft with cross-onshore winds and choppy surf. Monday the 31st offers a brief window of cleaner conditions with cross-offshore winds and a 2 ft swell from the SSW, but the wave periods are short and energy is low (76). It’s not going to be worth rushing for.

From Tuesday, September 1st, through the middle of the month, the swell collapses. Most days show swell heights under 2 ft, often with long periods over 10 seconds but barely any push. The combined energy readings are pitiful—mostly single or low double digits. Wednesday the 2nd is dead flat at 0.3 ft. There’s a slight bump on Saturday the 5th with 3 ft from the SW, but it’s onshore and choppy again. The 6th of September sees another pulse, 5 ft from the W with moderate energy (340), but it’s cross-shore and lumpy.

The rest of the run into the second week is tiny, with most swells under 1 ft and little to no energy. The only clean-looking slot is Monday the 8th of September afternoon, with a light offshore breeze and a 1 ft swell from the WSW, but you’d be surfing ripple soup.

Overall, there are no standout days. Caerhays is inconsistent at the best of times, and this forecast is a blank run. It’s one of those periods where you’re better off checking the wind and hoping for a last-minute change. Forecasts can shift, but right now, leave the board in the van.

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.
