The Lowdown
Alright, folks, Rusty here. Gotta be straight with you – this is a tough one. We’re looking at a 16-day window for the Caerhays area, and I’m not gonna lie, it’s a flat spell. There are no good surf options on offer here. The whole period is a long, drawn-out run of tiny, insignificant waves.
We’re talking about a stretch from the start all the way through to the end of the forecast, with nothing that breaks the 2 ft mark. The swell energy is practically non-existent, with the combined energy for all swells directed here barely ever getting into double digits, and often sitting at a measly 1 or 2 (weak energy). It’s a desert out there.
The first real whisper of anything happens much later, on Tuesday the 28th of July. The afternoon shows a slight bump, with a 2 ft swell from the west. The wind is a clean moderate breeze from the northwest, so it’s cross-offshore and clean. The combined energy is a whole 41 (weak energy) – still a tiny number. It’s not rideable, but it’s the biggest we’ll see. The water temperature is a very unusual 68°, which is much warmer than normal for this time of year.
For the rest of it, we’re looking at 0.3 ft swells, often with painfully long periods of 18 seconds or more. That’s groundswell, but with zero height, it’s just a wobble on the horizon. The water stays clean a lot of the time, with plenty of glassy or offshore conditions, but there’s simply nothing to surf on. It’s a real shame, but this is one of those times where the forecast can change – a blank run like this can’t last forever.
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.
