The Lowdown

G’day, it’s Rusty here.

Well, I’ll be honest with you—it’s a pretty flat stretch coming up for Caerhays. The next couple of weeks are looking mighty lean, with almost nothing surfable on the horizon. You’re looking at a solid run of poor surf conditions, with the swell struggling to get above 1ft on most days.

The first week is a real struggle. From Friday the 14th right through to the 26th of August, we’ve got no surf on offer at all. Swell heights are mostly below 0.6ft, and when there is a little pulse, it’s let down by the direction or just too weak to do anything. The wave energy is weak, with values in the low teens and twenties for most of that period. There are a couple of mornings with glassy conditions, like the 22nd with a light easterly, but with 0.3ft on the face, it’s not worth getting wet for.

Now, there is a glimmer of something at the very tail end of the window. Keep your eyes on Friday the 28th of August. The models are showing a strong pulse of south-west groundswell starting to roll in. By the morning we’re looking at 6ft of swell from the south-west, with a solid 13-second period. That’s a proper groundswell, the kind that gets the heart pumping. The wrap is coming from the optimum SSW direction for Caerhays, so it should have some push. The combined energy leaps to 1092, which is a very strong signal. The wind is cross-off from the north-east at 22 mph, which will be blowing right across the face, keeping it clean but with a bit of texture. This is the standout of the window.

It builds a touch more into the afternoon, with 7ft and the energy hitting 1438, but the wind jumps to a strong 28 mph. At that size, with that wind, it could get a bit wild, and it’ll be one for the experienced crew only. It’s over 5ft, so definitely not for the beginners.

Saturday the 29th still has some pretty solid waves – 3ft in the morning with a fresh offshore north wind, and then 4ft in the afternoon as it eases. The period drops slightly to 11-12 seconds, but the energy is still moderate at 351-423. It’s nothing like Friday’s peak, but it would still be a fun, clean option.

So, for the long-range outlook, that Friday the 28th is the one to circle on the calendar. It’s a long way out, so I’d say it’s promising, but we’ll have to see how it firms up. The water temp at the start of the spell is 66°, which is about 3° warmer than average for this time of year – that’s a touch warmer than normal, so the rubber might not be as thick.

It’s been a lean couple of weeks, but that last swell is worth waiting for.

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.
