The Lowdown
Right then, let’s have a look at what’s on the menu. Honestly, it’s a bit of a sad picture for the next couple of weeks. The swell window is just not cooperating, and we’re looking at a whole lot of flatness with barely a ripple to get excited about. The water at Caerhays is sitting at about 66°F, which is a touch warmer than normal for this time of year, but that’s about the only highlight.
The outlook starts on Sunday the 2nd of August with just a tiny 0.3m (1 ft) of weak, short-period W swell, but the wind is cross-on from the SE and it’s choppy. That’s a no-go. Monday the 3rd is even smaller, barely 0.2m (0.7 ft), and cross-on. Tuesday the 4th sees a jump to 0.9m (3 ft) from the SSW, but the period is a shocking 5 seconds and the wind is a fresh cross-on at 19 mph. The combined swell energy is only 70 (moderate energy), but the conditions are lumpy and unsurfable.
We get into Wednesday the 5th with that same 0.9m (3 ft) of SW swell, and the wind swings to a fresh W cross-off, which cleans it up a bit, but the energy is still weak at 88 and the height is piddly. It’s the same story through the rest of the first week: tiny, inconsistent, and mostly wind-affected. By the time we hit Sunday the 9th, the swell has dropped to barely 0.1m (0.3 ft). There’s a long gap here with absolutely nothing worth paddling out for.
The second week is more of the same. A slight blip on Tuesday the 11th with 0.9m (3 ft) from the ESE, period of 5 seconds, and light cross-off wind creates clean surf, but the energy is still weak at 39. It’s not enough to get a proper wave. There’s a brief moment on Thursday the 13th with a gentle offshore from the NNW, but the swell is only 0.2m (0.7 ft). Friday the 14th sees a moderate offshore at 16 mph with a tiny 0.4m (1 ft) of sloppy 3-second period swell.
There is simply no standout period. The only break on the map is Caerhays, an inconsistent spot that only breaks when the wind and swell align, and they just don’t for the entire 16 days. It’s a blank run for the area.

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.
