The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s looking bleak. We’ve got a long, dry stretch of nothing but flatness ahead. The first real hint of any surfable swell doesn’t show up until well into the second week. From now until late July, it’s a total write-off. We’re talking about a solid week of almost no energy at all, with the combined swell energy barely hitting double digits – it’s mostly just a sad trickle of 2 to 12 units. You’d be better off cleaning your board than staring at the ocean.
The only spot in the game is Caerhays. It’s an inconsistent little cove, and it rarely turns on, but it’s the only option we’ve got. The water is absolutely roasting – 68°F – which is a massive 6°F warmer than normal for this time of year. That’s pretty wild.
Now, the first faint pulse shows up around the morning of Wednesday, 30 July. A tiny 3ft swell from the ESE, with a combined energy of 37. It’s small, but we’ll take it. The wind is light and variable, keeping things clean. By the afternoon, the cross-offshore wind picks up to 16 mph, which will keep the surface clean, but it’s still only 3ft. This is the absolute best we’ve got – a small, clean, glassy morning. Don’t expect barrels, but for a longboard or a funboard, it might just be enough to get a wriggle on.
After that, the energy drops off again. The morning of Friday, 1 August sees a little 2ft bump from the SSW with a moderate offshore wind, but the energy is weak. Then Saturday, 2 August has a slightly bigger 3ft SSW swell, combined energy up to 39, but it’s still small. It’s the best of a bad bunch, but honestly, it’s not worth getting excited about.
The rest of the period fades back into tiny, un-rideable slop. For a spot that’s already inconsistent, this is a proper blank run. It’s gonna take a change in the weather pattern to get anything going. We’ll have to keep an eye on the charts.
Stay patient.

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.
