Alright, Rusty here from Caerhays. Got to keep it real – the swell window is just about closed for the next week and a half. This is a proper flat spell.
Water temp is sitting around 63°F – noticeably warmer than average for this time of year, so at least a quick dip doesn’t sting.
From Friday July 3rd all the way through to Thursday July 9th, there’s next to nothing. Swell heights between 0.3ft and 0.7ft at best. Wave energy is weak – the highest reading in that stretch is 24 on Friday arvo, and most of the time it’s in the single digits. Mornings are mostly clean with cross-off offshore or even glassy wind, like Wednesday the 8th with 0.3ft and dead calm – looks great, but you can’t surf glass.
Things change on Friday July 10th when the swell picks up to around 4ft to 4ft from the ESE, period is real short at 5 to 6 seconds though. Combined energy hits 75 to 92 – moderate. But the wind is cross-shore and messy, and with that short period, it’s windswell. Not good for a paddle board.
The one and only proper window is the morning of Saturday July 11th. Swell sits at 4ft from the ESE (energy 102 – the best in the whole run) and the wind goes clean offshore from the north. At Caerhays (Cornwall), that’s the best setup we’re going to get. The optimum swell direction is SSW, so the ESE isn’t a perfect match, but with light offshores and some size, you could sneak a few. Expect crowds on the weekend. The period is only 6 seconds though – so it’s short-interval windswell, not the long lines we’d hope for.
Saturday arvo drops off into light cross-onshore junk. After that, the rest of the second week is tiny with occasional glass but no real push. Best other moment is the morning of Friday the 17th – 0.7ft and clean offshore – but way too small to get excited about.
The call is simple: if you really need a surf, aim for Saturday morning July 11th. Otherwise, it’s a long flat run. Might not stay that way – forecasts shift – but right now, it’s calm out there.
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.
