The Lowdown
Alright, let me level with you. It’s a tough stretch ahead for Caerhays. The whole 16-day window is a bit of a write-off, so don’t be holding your breath for anything epic. We’ve got a long gap with barely a ripple.
Right now, and for the next several days, it’s flat. Like, really flat. We’re talking about a tiny 0.3 ft splasher from the south with a long period, but the combined wave energy is a measly 2 (weak energy). The water temp is sitting at 67°F which is much warmer than usual for this time of year – a solid 5°F anomaly. But that’s about the only interesting thing. The wind is light and cross-off on Saturday the 18th, but there’s just nothing to ride.
The pattern stays dead through Sunday the 19th and Monday the 20th, with onshore and cross-shore winds and swell heights barely cracking 0.3 ft to 2 ft. The energy readings are all in the single digits or low 20s. It’s a real bummer.
We get a glimmer on Tuesday the 22nd with a clean offshore wind from the north, but it’s still only 0.3 ft of south swell. Clean conditions, but it’s a lake. This continues through the end of July – clean skies, light offshores or cross-offshores, but the swell just doesn’t show up. It’s frustrating.
The only real pulse of energy comes right at the very end of the outlook. On Thursday the 30th of July, we see a 3 ft swell from the southwest, with a short period of 4 seconds. The combined energy (37) is still weak, but it’s the biggest number we’ve seen. The wind is a clean cross-off from the WNW. That’s your best bet, but it’s still a short-period, weak swell in a beach break setup. It’s not going to be anything special.
Honestly, for this whole 16-day window, there’s nothing worth paddling out for. The setup is so weak and inconsistent that it looks more interesting for kite surfing than paddle surfing on the days with any wind. Keep the board in the car, but don’t get your hopes up. Forecasts can change, but this is a long dry spell.

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.
