The Lowdown
Alright, Rusty here. Let’s get this straight: the next 16 days are a tough watch for Caerhays. There’s not a single session that scores a recommendation, and the whole window is a write-off for paddle surfing. That’s a blank run, and for this area, that’s more normal than you’d hope. The forecasts can change, but right now, there’s nothing to get excited about.
The water is sitting at 64°F on the 1st, which is a touch warmer than normal for this time of year, but that’s about the only highlight.
The first few days are a mess. On Tuesday the 1st, we’ve got a tiny 1ft swell from the SW with a short 6-second period and a weak combined energy of 23. The wind is a cross-on 16 mph, making it choppy and poor. Wednesday the 2nd isn’t any better, with a 3ft swell, a 4-second period, and fresh cross-on wind. Thursday the 3rd sees a 2ft swell, but it’s still cross-on and messy.
Friday the 4th morning offers a 4ft swell from the SW with a 5-second period, and the wind is a cross-off 12 mph, so it’s clean. The combined energy hits 92, which is still weak. But with a 5-second period, it’s just not gonna have any push. The afternoon drops off to a tiny 0.7ft.
Saturday the 5th morning is glassy, with the wind dead calm from the ENE. The swell is a pathetic 0.3ft, though, with a 14-second period. That’s a long period groundswell, but there’s zero size. The combined energy is only 13. It’s a tease.
From Sunday the 6th onward, we’re stuck with tiny, short-period slop, cross-on or cross winds, and weak energy readings mostly under 100. Monday the 7th morning has a 2ft swell with a 13-second period and a combined energy of 117 (moderate), but the wind is cross 6 mph, and the poor surf quality rating says it all. The rest of the week is a cycle of wind, lumpy conditions, and occasional clean spells with no swell to back them up.
The second week is more of the same. Saturday the 13th morning has a 4ft swell from the SE, but with a 5-second period and a strong breeze of 25 mph cross-off, it’s clean but gutless. The combined energy is 76. It’s not worth paddling out for.
Given the persistent tiny swell, short periods, and the beach-and-reef setup, this window looks more interesting for kite surfing than paddle surfing. The few clean spells won’t deliver any waves worth riding.
No standouts here. I’m as disappointed as you are. Keep your eyes on the charts, but for the next 16 days, stay home.
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.
