The Lowdown
Alright folks, Rusty here. Let’s be straight with you right off the bat: this is a grim 16-day stretch for Caerhays. There’s simply nothing on offer that’s worth paddling out for. The whole forecast period is a write-off, with zero surfable waves. We’re looking at a full blank run from the start of the forecast right through to the end.
The first few days are the worst of it. From Friday the 31st of July, right through the weekend and into the following week, the swell is next to nothing. We’re talking about tiny, weak waves of just 0.3 ft to 0.7 ft coming from the west with combined energies barely hitting double digits (2 to 12). The water temp is a notable 66°F with an anomaly of 4°F – that’s much warmer than normal for the time of year, so you’d be warm if you went in, but there’s no point.
There’s a slight flicker of hope on Wednesday the 5th of August, where the afternoon sees a clean offshore wind from the NNW, but the swell is still a pathetic 2 ft from the SSW with a combined energy of just 32. It’s clean, sure, but there’s not enough oomph to push a surfboard.
The pattern continues through the second week. The 8th of August morning is glassy – dead flat calm – with a 2 ft swell from the SW, but the combined energy is only 27. It’s pretty, but it’s not surfable. The only real standouts in terms of wind are the clean, offshore days, but the swell is just too small to ever get excited about. By the 15th of August, we’re back to 0.3 ft dribble with fresh offshore winds.
Honestly, for a spot like Caerhays, which is fairly exposed to the swell, this kind of dead run is more normal for this time of year. It’s frustrating, but it’s the reality of the 16-day window. The forecasts can always change, so keep your eyes peeled, but for now, leave the board in the car.
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.
