The Lowdown
Right folks, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s a grim stretch for Caerhays. We’re looking at a solid run of flat, poor surf conditions that goes on for days. The first real sniff of anything rideable doesn’t show up until the morning of Sunday the 9th of August, so that’s over a week of nothing. The wind and swell just aren't lining up.
The main event, and the only thing worth getting excited about, is that Sunday morning. A solid 8ft swell from the WSW, with a period of 10 seconds, is swinging in. That’s a lot of water, with combined energy readings hitting 1347, so it’s proper strong. But here’s the catch – that’s well over 8ft, so it’s strictly for the experts. The wind is a cross-shore moderate breeze, so it won’t be perfect, but it’s not blowing it flat. For the rest of the day, the wind swings cross-offshore and the swell drops right off, so that Sunday morning window is the one and only stand-out.
The week prior is a total washout, with tiny swells, poor winds, and the water temperature is sitting at 67° – that’s a whopping 5° warmer than usual for this time of year, which is a real treat if you were hoping to get wet, but the surf just isn’t there.
The only other time we see a bit of life is the afternoon of Monday the 3rd of August, with a 3ft swell from the SSW, but the period is a terrible 4 seconds and it’s onshore, so it’ll be all chop and no shape. Not worth a paddle.
So, there you have it. If you’re a seasoned charger, mark your calendar for the morning of the 9th of August. Otherwise, it’s a long wait.
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.
