The Lowdown
Alright folks, Rusty here. Let’s be real about this one – it’s going to be a long, flat wait.
We’re looking at a stretch of days where the ocean just isn’t going to give us a proper wave. The entire 16-day window is basically a write-off for decent surf. From the start of the forecast on Wednesday, July 29th, right through until the end on Thursday, August 13th, every single report is marked as “poor surf conditions.” That’s a solid run of nothing.
The water is weirdly warm, about 66°F, which is a solid 4°F above what we’d normally expect for this time of year. That’s a strange feeling, paddling around in a bath while the waves are just a flat, glassy nothing.
For the first few days, the swell is tiny – we’re talking 0.3ft waves with virtually no energy. The combined energy reading is in the single digits. That’s barely a ripple. The wind is mostly cross or cross-off, but it doesn’t matter because there’s nothing to ride.
We get a tiny blip on Monday, August 3rd, with a 2ft swell from the east, but the period is a shocking 3 seconds. That’s pure wind chop, not a wave you can paddle onto. The energy hits 16, but it’s still useless.
There’s a slight lift on the 4th of August, with a 2ft swell from the ESE and a combined energy of 54, but the period is still a short 7 seconds making it messy and cross-shore.
The cleanest conditions in the whole outlook actually come on the 5th of August, Wednesday morning, with a strong offshore NNW wind at 16 mph. But that 2ft swell at 6 seconds just doesn’t have the push to make it worthwhile. The energy is moderate at 40, but it’s a tease.
Later in the forecast, on the 11th, we get a fresh offshore wind from the NNW at 19 mph, but the swell is a pathetic 1ft. It’s clean, but there’s simply nothing to surf.
The closest we get to anything surfable is a 3ft swell on Thursday, August 13th, from the ESE with a 5-second period, and it’s getting hammered by a 19 mph cross-shore wind. The energy is 27, and the comment says “fresh cross-shore with lumpy cross-chop.” That’s a mess.
Honestly, this is a classic case of a long dry spell. For a spot like Caerhays that’s “inconsistent” at the best of times, this kind of flat run is more the norm than a surprise. There’s no standout session, no secret window to chase. The best advice is to wax the board, check the forecasts daily, and wait for the next system to breathe some life back into the ocean. Stay patient, crew.
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.
