The Lowdown
Hey folks, Rusty here. I’ve been through the numbers for Caerhays and the story is plain: there’s nothing on the table for the next 16 days. Every single session from now through the end of July is marked as poor surf conditions with zero scores. The swell is puny, the wind’s messing things up, and the wave energy is bottomed out. It’s going to be a long, quiet stretch.
Let’s go day by day. Starting Wednesday the 15th, we’ve got some clouds and a fresh cross-shore breeze out of the east at 19 mph kicking up lumpy chop on a 3 ft ESE swell with a period of only 5 seconds – weak energy (48). That afternoon the wind eases but stays cross-shore, swell bumps to 4 ft but still short period (6s) and poor. Thursday the 16th is even smaller – 2 ft from the east, period around 5s, gentle cross-shore wind, energy down to 21-31. Friday the 17th we’re down to 1 ft, light cross-on breeze, energy in the teens. Saturday the 18th sees the swell almost vanish – 0.3 ft from the south with a long period (13s) but no height to ride, energy of 2-3. The wind briefly goes offshore from the north-northeast so it’s clean, but there’s nothing to catch. Sunday the 19th, wind picks up again from the east at 19 mph, 2 ft E swell, period 3s, fresh cross-shore chop – hopeless. And it stays that way through the end of the month.
From Monday the 20th onward, we get clean offshore winds but swell heights stay at 0.3 ft or 0.7 ft. A few windows have longer period swells (14-18s) from the south, but the height is so tiny there’s zero wave energy (values like 2 to 10). Water temp is running well above normal – 66°F, which is nearly 5° warmer than average for the time of year – but that doesn’t help when there’s no surf. Caerhays is an inconsistent spot anyway, and this blank run is pretty typical for the area when conditions don’t line up. Crowds can show sometimes, but right now the lineup will be empty. Forecasts can always shake out differently, but this window is a wash. Stay patient, check back later. 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.
