The Lowdown
Alright folks, Rusty here. Let me tell you, it's a bit of a grim outlook for the Caerhays region over the next couple of weeks. Honestly, there's not a single recommendation in the entire 16-day window. Every single reading has "poor surf conditions" flagged, so we're looking at a long, flat stretch with nothing worth paddling out for.
The water is sitting at about 66°F, which is a touch warmer than normal for this time of year, but that's about the only thing going for us.
Let's break it down. The first week is a write-off. We start Sunday, the 2nd of August, with tiny 0.3ft swell from the SW and a cross-shore breeze. The combined energy is pitiful, reading just 4 (Sunday morning) and 6 (Sunday afternoon). That's barely a ripple. Through the rest of the week, we get a bit more wind but no real size. Monday and Tuesday see the swell bumping up to a measly 0.7ft and 1.0ft, but with onshore or cross-onshore winds, it's just messy and choppy. The energy does climb to a moderate 70 by Tuesday morning, but it's all short-period windswell making for poor quality.
Mid-week, Wednesday the 5th, we get a 2ft swell from the SW with a fresh cross-shore wind, but it's lumpy and ugly. The energy is still weak in the 59-64 range. Thursday and Friday the 6th and 7th drop right back down to 0.3ft to 1ft. Even though we get a moment of glassy conditions on Friday morning, the swell is just too small to do anything with. The energy is barely registering, in the single digits.
The second week doesn't offer much hope either. There's a very slight uptick on the 12th of August, where we see a 4ft swell from the ESE with a moderate energy reading of 108 to 109. The wind is cross-offshore, which is good for shape, but the period is a short 6 seconds. At 4ft, it's a manageable size, but with that short period and poor quality label, it's just not going to be a good wave. That's about as close as we get to a pulse. After that, it dribbles back down to 1ft to 3ft for the rest of the period with clean but weak conditions.
So, there you have it. The entire 16-day window is a bust. Sometimes you get blank runs like this, and it's just a waiting game for the next proper swell to show up on the charts. Keep an eye on the forecast, but for now, the board stays in the van.
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.
