The Lowdown
Alright, I’ve been through the numbers for Caerhays over the next 16 days, and I’m calling it as I see it. From the 19th of July right through to the start of August, it’s a flat spell. No two ways about it. The swell heights are barely a whisper – 0.3ft to 0.7ft for the most part – and the combined swell energy is nearly always in the low single digits or teens. That’s weak. So there’s a real gap here, stretching the whole forecast period, with no surf worth paddling for.
The water temperature at Caerhays is about average for this time of year, so that’s not the problem. The problem is just no swell. We get a few clean windows, like the 22nd of July with a gentle offshore breeze, or the 23rd with a glassy afternoon. But with a wave height of 0.3ft to 0.7ft, and a period that’s all over the shop, it’s not going to break. The swell direction is mostly from the south or west, but Caerhays really needs a good SSW groundswell to work.
There’s a tiny blip around the 28th of July, where the combined energy hits 24 (moderate) and the swell is from the WSW at 0.7ft, with an 11-second period. It’s clean with a cross-offshore wind, but that’s still a knee-high wave at best. Not worth the drive.
Then on the 31st of July, the wind gets strong from the east, and the combined energy climbs to 28, but it’s messy and cross-shore, and the swell is still only 0.7ft. That’s a breeze for kite surfers, not a wave for a paddle surfer.
So I’ll be straight with you: there are no good surf options in this 16-day window for Caerhays. It’s a dead run. For a spot that’s inconsistent anyway, a flat stretch like this is pretty normal. But forecasts can turn around. Keep checking, but for now, it’s a no-go.

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.
