The Lowdown

Alright, Rusty here again, giving you the rundown in feet and miles per hour.

Look, I’ll cut to it – Caerhays is looking like a ghost town for surf the next 16 days. There’s a big ol’ gap of nothing from the start. Wednesday the 16th kicks off with a tiny 1ft swell out of the WSW, period of 11 seconds, and a solid 15 mph cross-off wind. Combined energy is a weak 49. Water temp is 64°, a touch warmer than usual for September. But the surf is poor, plain and simple.

Thursday and Friday are more of the same – tiny, choppy, cross-shore junk. Saturday the 19th sees a slight bump to 2ft, but it’s short-period windswell, and the cross-shore wind ruins it. Not worth the drive.

Then it goes dead. Sunday the 20th through Tuesday the 29th is a long stretch of ankle-biters or blown-out slop. There’s a brief moment on Tuesday the 22nd with a 2ft, 17-second groundswell from the SW, and the energy hits a moderate 160. But the wind is a cross-shore mess. That long period would be sweet on a point break, but Caerhays is a beach, so it’ll just close out and be a pain to paddle for.

Friday the 25th finally sees some size – 5ft from the ESE, moderate energy of 253. But it’s getting hammered by a 22 mph cross-shore wind, making it lumpy and ugly. That’s kite-surfing weather, not surfing weather. Same story through the weekend.

The best shot comes on Wednesday the 30th – a 4ft SSW swell with an 8-second period, energy of 278, and finally a clean cross-off breeze. That’s the one window that might offer a few rideable waves, but it’s still not a standout.

So, bottom line: don’t hold your breath. There’s no day to circle on the calendar. The 30th of September is your best bet for anything clean, but that’s about it. Sometimes the ocean just takes a long nap.

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.
