The Lowdown
Alright folks, Rusty here. Let's have a look at what the next couple of weeks are holding for us at Caerhays.
Well, I'll be honest with you, it's looking like a bit of a flat spell for the foreseeable future. We've got a 16-day window here, but honestly, it's going to be a struggle to find anything rideable. The first real chance of a wave doesn't even show up until Saturday the 16th of August, and even then it's tiny. There's a solid gap of over a week with nothing worth paddling out for, so don't bother checking the charts until then.
Now, Caerhays is a fairly exposed spot that likes a SSW swell, but we just aren't getting it. For the first week, it's all tiny scraps of swell from the SE and S, with periods so short you could count them on one hand. Winds are mostly cross or cross-off, but with waves barely reaching 1ft, it's a total non-event.
Let's run through the dates. Saturday the 9th and Sunday the 10th of August, you've got 0.3ft to 1ft of swell. It's clean on the Sunday with a light WNW cross-off, but there's nothing to ride. The following week is more of the same: a bit of bump from the ESE on Tuesday the 12th, but it's cross-shore and choppy, with the wave energy barely registering (45). Wednesday the 13th sees a tiny 1ft groundswell from the WSW with an 11-second period, and it's clean with a NW cross-off, but still, it's just not enough.
We do see a little spike on Wednesday the 19th of August, with the swell bumping up to 3ft from the SW. It's clean with a light NW cross-off and a weak period of 4 seconds. The energy is still low (26), but for a moment there, it might just be enough for a longboard or a foiler if you're desperate. But for a standard surf, it's still poor.
Saturday the 16th of August has a tiny 2ft pulse from the east with a 4-second period and a cross-off wind, but again, the energy is minimal (11). It's not going to get your heart racing.
The water temperature is sitting at 66°, which is a touch warmer than normal for this time of year, so you won't need a thick wetsuit, but you'll be needing a lot of patience.
To be brutally honest, there isn't a single standout session in this entire forecast. It's a flat run. The setup is more interesting for a kite surfer than a paddle surfer if the wind ever gets right, but for us wave riders, it's a waiting game. Forecasts can change, but right now, don't hold your breath.
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.
