The Lowdown
Alright, this is a tough one, I'm not gonna lie. Caerhays is a fairly exposed spot, and it loves a solid SSW swell, but the charts are looking pretty grim for the next couple of weeks. We've got a real dry spell here, folks.
The water is sitting at 64°, which is a touch warmer than normal for this time of year, but that's the only easy thing going on.
Let's break it down. We kick off on Wednesday, 26 August, with a tiny 0.7 ft of swell and a cross-on wind. That's a no-go. The whole first week is a write-off. We've got a couple of days where the swell pushes up to 5 ft, like on Saturday morning, but with a 25 mph cross-on wind and a combined energy of 203, it's a mess. Saturday afternoon gets even uglier with a 31 mph near gale and 7 ft of swell (combined energy hitting 525), but it's all cross-shore mayhem. That's more kite-surfing territory than paddle surfing.
The only real glimmer of hope comes on Monday, 7 September morning. We get a clean 2 ft wave with a light cross-offshore breeze from the WNW. It's tiny, only 2 ft, and the combined energy is a weak 44, but it's clean. That's the best we've got in the first week and a half.
Then, we hit a big gap. Nothing of note until Saturday, 5 September. That morning, we finally get a brief window. The wind goes light offshore from the north at 6 mph, and we get a 1 ft groundswell out of the WSW with a period of 12 seconds. The combined energy is only 72, so it's weak, but it's the cleanest wave in the entire outlook. The long period will make for some nice, shaped lines, but for a beach break it might be a bit too straight. Still, if you're desperate, that's the session.
After that, we're back into the doldrums. The rest of the second week is a mix of tiny swell and onshore wind. Monday, 9 September afternoon has a clean 3 ft wave with a cross-offshore breeze, but it's coming from the SSW at a weak 4-second period, so it's just a bump.
Honestly, looking at the whole 16-day window, there's nothing to get excited about. The only standout, if you can call it that, is that Saturday 5 September morning session. It's clean, it's offshore, and it's a long-period groundswell. But it's small, and the break is inconsistent at the best of times. Everything else is poor surf conditions. The forecasts can change, but right now, it's a tough run for Caerhays.

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.
