The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.
It’s a quiet stretch ahead, I’ve got to be honest. The first proper surf recommendation doesn’t pop up until the 9th of August, so there’s a solid gap of over a week with practically nothing to get excited about. From the 31st of July right through to the 8th of August, it’s all tiny, weak waves with poor conditions. You’re looking at flat spells and choppy, onshore slop. Not worth paddling out for.
Things finally start to show a pulse on Sunday morning, the 9th of August at Caerhays. The water is sitting at 66°F – that’s 4°F warmer than normal for this time of year, so it's notably warm. The swell is coming from the southwest at 3 ft, with a period of 9 seconds, and the combined energy is moderate (101). The wind is a cross-off from the northwest at 16 mph, keeping things clean. That’s your best bet for the whole forecast window. It’s not huge, but it’s the only time the energy really ticks over into the moderate zone. The break is inconsistent, so you’ll have to be patient, but when a set comes through, it’ll be rideable. Crowds are possible.
Monday the 10th of August holds similar energy. The morning sees 3 ft swell from the southwest again, 8-second period, with a light cross-off breeze from the west-northwest at 9 mph. Combined energy is still moderate (107). The afternoon lifts to 3 ft from the south-southwest, but the wind picks up to 12 mph, still cross-off. It stays clean, but the wave quality is still only poor.
After that, it fades again. The 11th and 12th drop back into the weak stuff, with onshore winds and choppy conditions. The 13th through the 15th offer some clean cross-off winds, but the swell is tiny and weak, with combined energy barely hitting 40. Nothing worth calling a standout.
So, to sum it up: the only real window is the 9th and 10th of August. Sunday morning the 9th is the pick of the bunch. Don’t hold your breath for the rest.
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.
