The Lowdown
Alright, folks, this is Rusty. Let’s run through the same outlook, but in feet and miles per hour.
Well, it’s a tough one. The next 16 days at Caerhays are looking pretty flat. There’s a big gap with no real waves to start, and the whole window is pretty uninspiring. We’re talking small, weak energy and poor to moderate winds making it a write-off. The few little bumps we get are barely worth paddling out for.
The first real chance to get wet doesn’t look likely until deep into the second week. The water’s at 64°, which is a touch warmer than usual for this time of year.
Looking at the calendar, over a week from now, on the morning of Monday, September 16th, there’s a tiny pulse of 0.7 ft from the WSW with a 12-second period. The combined swell energy is a measly 15, barely a ripple. The wind is light from the NNE at 6 mph, keeping it clean. But it’s so small, it’s really just for the groms on a foamie.
Then, the afternoon of the 16th of September is the closest we have to a standout. The swell is still a tiny 0.7 ft from the WSW, with an 11-second period, and the combined energy is a weak 13. But the wind drops to a glassy 3 mph from the ESE. That’s proper glass. If there’s a ripple, it’ll be the cleanest ripple you’ll see all fortnight. The break is inconsistent, and it’s for beginners, so you won’t be fighting for a wave. Just don’t expect any power.
The rest of the 16-day run is a mix of onshore winds, flat spells, and choppy conditions. The biggest swell we see is a 3 ft pulse from the WSW on the afternoon of Wednesday, September 9th, but it’s a short 8-second period and the wind is a cross-off. The combined energy (104) is the only moderate reading of the whole period, but the quality is still poor. It’s a beach and reef setup, and with those conditions, it looks more interesting for a kite surfer than a paddle surfer.
Honestly, it’s a blank run. For this area, this kind of flat spell is normal. Don’t lose hope, though – forecasts can change. Keep an eye on it.
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.
