The Lowdown
Right then, let's have a look at what's on the cards for the Caerhays area over the next couple of weeks.
Honestly, it's a pretty flat and quiet picture for the bulk of the forecast. We're looking at a long stretch with barely a ripple. From now, right through until the start of August, there's next to nothing doing. The swell heights are tiny, often just 0.3ft, and the energy is next to zero. There are a few glassy early mornings and clean afternoons, but that doesn't matter much when there's no wave to surf. It's a proper blank run.
The first real glimmer of hope doesn't show up until Saturday, the 1st of August. Through the afternoon, we finally see a slight bump with a 2ft swell from the WSW. The combined energy gets up to a weak 107, which is something, but it's crossed up with a moderate onshore breeze. It's still looking pretty messy and poor.
Then come Sunday, the 2nd of August, there's a bit more size pushing in, with 3ft from the SSW. That's the biggest we see, but again the wind is onshore from the SE, making it choppy. The period is a short 5 seconds, so it'll be weak, disorganised windswell.
The only half-decent note comes right at the end on Tuesday the 4th of August. The afternoon shows a 2ft swell from the WSW with a moderate 8-second period, and the wind turns cross-off from the NW. The combined energy jumps to 57, and the comment describes it as "surfable waves but very ordinary conditions". It's not great, but it's the closest we get to a paddle. Even that, you wouldn't go out of your way for.
The water temperature is a massive 5° warmer than normal, sitting at 67°, which is very unusual for the time of year. That's the only standout feature.
So, there are no standouts here. It's a long, dry spell with only a few days of very ordinary, choppy small waves. For a spot like Caerhays, which is inconsistent at the best of times, this kind of blank run is more normal for the area. Forecasts can change, but right now, it's a waiting game.

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.
