The Lowdown
Alright, let’s get into it. The outlook for the next couple of weeks is looking pretty flat for us, to be honest. The Caerhays area is in for a long, quiet stretch with hardly anything worth paddling out for. There’s a real gap here – from right now all the way through to around Sunday the 13th of September, there just isn’t any decent surf to speak of. The first real glimmer of hope won’t show up until then, so if you’ve got itchy feet, you’ll be waiting a while.
Come Sunday morning, the 13th, we finally see a pulse. Swell height hits 4.9ft, coming out of the west with a 10-second period. That’s not massive, but the combined swell energy is sitting at 500 (moderate), so there’s some real push behind it. Winds are light, cross-off from the west-northwest, keeping things clean. This is the standout window – the best we’ve got. It’s not for beginners though, as that 4.9ft is right on the edge of being too much for the less experienced. For the crew who know what they’re doing, this is the time to be out there. Water temp is a touch warmer than normal at 64°, nothing crazy, just a bit above average for this time of year.
After that Sunday morning window, the swell drops right off again. The rest of the week and into the next is a sea of flat, small, and generally poor conditions. There’s another tiny blip on Friday the 25th of September – a morning session with 4.3ft from the east-southeast, 8-second period, and clean offshore from the north-northwest. The combined energy is 201 (moderate), so there’s a little bit of life there, but it’s very ordinary and not worth getting too excited about. The afternoon gets blown out by strong winds.
Honestly, if you’re looking at the 16-day stretch, your best bet is that Sunday the 13th, and even that is a short-lived window. The rest is a waiting game. Keep your eyes on the charts, but for now, it’s mostly a write-off.

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.
