The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Honestly, I’m looking at a pretty grim stretch ahead. The first week and a half is a real write-off. From Friday the 24th of July right through to the afternoon of Friday the 7th of August, it’s just flat. We’re talking tiny dribbles of 0.3ft to 0.7ft swell with next to no energy, and the wave comment is screaming “poor surf conditions” every single day. There’s a gap of nearly two weeks where you’d be better off polishing your board than paddling out. The water temp is sitting at a very unusual 67°, which is a whopping 5° warmer than normal for this time of year at Caerhays, so it’ll feel like a bath, but that’s about the only thing going for it.
Now, there is a little flicker of hope right at the tail end of the run. Around the morning of Saturday the 8th of August, we finally see a pulse of swell arrive. It’s not big, coming in at 4ft from the SSW, but the energy is starting to build (129). The wind is light offshore from the north, which is a major positive for clean conditions. The period is short though, only 7 seconds, so it’ll be a bit lumpy and weak. By the afternoon, it’s 4ft from the SW with a similar period and a gentle cross-off breeze, keeping things clean. The combined energy ticks up to 147, which is moderate. This is the only window in the whole 16 days that even sniffs a surfable wave.
So, the standout here is the morning of the 8th of August at Caerhays. The offshore wind is the key. It’s the only time the conditions are even close to decent. The swell is tiny, so it’s fine for beginners, but don’t expect any power. The afternoon is a close second with a similar clean setup. For the rest of the run, it’s a total blank. The forecast can change, and it tends not to stay this flat forever, but for now, mark your calendar for the 8th if you’re desperate.
Stay patient, lads.

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.
