The Lowdown
Alright, Rusty here again. Let's break down the Caerhays forecast for the next couple of weeks.
Honestly, it's a tough start. We're looking at a solid stretch of flat, tiny, or just plain messy conditions from now until the end of July. The first 10 days have surf that's barely a ripple, never getting above a paltry 0.7ft, and the wind is all over the place. There's a few days of clean cross-offshore wind, but with no swell to push it, it's a total non-starter. You'd be better off taking the dog for a walk.
We finally see a bit of life kick in on Saturday, the 1st of August. The afternoon brings a jump in swell to 4ft from the SSW, with a period of 6 seconds, and clean cross-offshore winds from the WNW. The combined energy is still weak at 95, but it’s the first real sign of something surfable. It’s not a world-beater, but it’s a start.
The pick of the entire forecast is the morning of Sunday, the 2nd of August. Now we're talking. The swell is 3ft from the SW, but the period has stretched out to a nice 10 seconds, giving it some proper push and shape. The combined energy is moderate at 122, and we’ve got light offshore winds from the North. That’s glassy, clean conditions. This is the one you want to circle on the calendar. The water is a balmy 68°, which is a full 6° warmer than usual for this time of year – that’s very unusual, so you’re in for a treat.
After that little window, it drops off again. The rest of the first week of August is back to junky, small, and onshore slop, with the swell struggling to get above 3ft and the wind turning cross-onshore. The last couple of days of the forecast, around the 7th, show a bit of a clean-up with offshore winds, but the swell is still tiny at 2ft.
So, to be honest, there’s only one true standout in this whole 16-day window: the morning of Sunday, the 2nd of August. Get out there early for those clean, waist-high lines from the SW. It’s a short window, but it’s your best shot.

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.
