The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for our little stretch of coast.

To be straight with you, the next two weeks look pretty grim. We’ve got a real quiet spell ahead with nothing worth paddling out for. The forecast is stuffed with poor surf conditions day after day. There are no standout waves on the horizon, and the only break we’ve got to look at is Caerhays. It’s an inconsistent spot that’s notoriously fickle, so a blank run like this is more normal than unusual for the area.

The water temp is sitting at 64°, which is a touch warmer than normal for this time of year, but you won’t be feeling it much from the beach.

Let’s break it down. Starting Friday the 28th of August, it’s small and messy. A weak 2 ft SW swell with only 6 seconds between waves will be getting chopped up by a strong cross-shore wind. That's a solid no. Saturday the 29th sees a jump in size to 5 ft from the S, but an onshore wind of 28 mph will make it a washing machine. By the afternoon, the wind swings to a cross-offshore and the swell refines a bit to 6 ft from the SSW with a period of 9 seconds. The wave energy hits 480 (moderate), but this would be tricky – the size and wind combo would still leave it lumpy and uninviting. Not one for a good time.

Sunday the 30th drops off quickly, and from Monday the 31st all the way through to Saturday the 12th of September, the swell never really gets going. Most days show swell heights under 3 ft, and the period is either short or the swell direction is wrong. We get some clean, glassy-looking pockets with offshore or cross-offshore winds, like on the morning of the 5th of September (NNW offshore at just 6 mph with a clean face), but even then, the swell is only 1 ft with no energy. A couple of afternoons in early September see a 17-second period from S, but it’s tiny – 0.3 ft and only 4 units of energy.

In short, the whole 16-day window is a bust. No standouts, no real quality. If you’re desperate, wait for a day with glassy, clean conditions and maybe catch a tiny knee-high wave, but honestly, save your energy. Forecasts can change, but right now, it’s a flat spell for Caerhays.

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.
