The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin' for the next couple of weeks.
Right off the bat, I gotta be straight with you: it’s a tough run. We’re lookin’ at a long, flat spell for Caerhays. From now, right through the end of July and into the first few days of August, it’s pretty much a write-off. The swell is tiny, rarely pushin’ past 0.7 ft, and the combined energy is laughably low – we're talkin' single digits and low double digits (4 to 9). You’ll see a bit of cross-off wind here and there, which keeps the surface clean, but with no wave to ride, it doesn’t matter. There’s a stretch from the 24th of July all the way to the 1st of August where there’s just nothin’ worth paddlin’ out for.
Now, we finally see a pulse of energy arrive around the 2nd of August. The swell starts to build through the day, hittin’ 4 ft by Sunday morning from the SW, with a short, weak period of 6 seconds. The combined energy finally climbs into three digits (134), but the wind is a messy cross-shore, so it’s gonna be lumpy. By Sunday afternoon, the swell bumps up to 5 ft from the SW, still with a poor 6-second period, and energy at 152. Still, the wind is cross-shore, so it’s not the cleanest. This is still a poor surf condition, and honestly, with that short-period windswell and cross-shore breeze, this setup looks more interesting for a kite surfer than a paddle surfer.
The real standout, and the only time I’d get excited, is Tuesday the 4th of August. The morning brings a surprise: glassy conditions with the wind swingin’ to the WNW at only 3 mph. The swell is 3 ft from the W, with a solid 7-second period, and the combined energy jumps to 163 – that’s the most juice we see the whole forecast. The report even says “surfable waves but very ordinary conditions,” which I’ll take as a win after this drought. That’s the morning to be on the water. It’s not a big swell, around waist to chest high, but it’ll be clean and fun on a longboard. The offshore wind for Caerhays is from the N, and the swell is from the W, so it’s not a perfect match, but the glassy conditions will make up for it.
After that, it fades fast. The rest of the second week is a dribble of small, weak swell with onshore and cross-shore winds. By the 7th and 8th of August, we’re back to near flatness.
So, to sum it up: the first week is a total bust. The only real chance is the morning of Tuesday the 4th of August. Keep an eye on it, but don’t hold your breath on the long-range stuff.
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.
