The Lowdown
Alright, Rusty here. Let's talk about what's on offer at Crantock. I've had a good look at the charts, and I'll be straight with you – it's a bit of a lean run for the next 16 days. There are no proper standouts to get wildly excited about, just a few windows where things might clean up enough for a paddle.
The big picture is a long stretch of poor surf. We've got a couple of weak pulses of swell, but the wind is going to mess with it for most of the period. The water temp is about average for the time of year, nothing unusual there.
Monday 10th through Sunday 23rd is a pretty grim stretch. The swell is tiny, mostly under 3 ft, and even when it does pick up a little, the wind is either cross-onshore or onshore, making it choppy and lumpy. The energy is mostly weak, often below 100 (moderate wave energy), and the period is short, so the waves lack any real punch. Don't bother.
There is a small glimmer of hope on Friday 21st August. We get a bit of clean-up with offshore and cross-offshore winds from the SE and ENE. The swell is a measly 2 ft from the west with a 10-second period, and the energy is only moderate at 128-134 (moderate wave energy). The conditions will be clean, with a gentle offshore breeze, making it surfable but very ordinary. This is the closest we get to a recommendation, and it's a weak one. The waves will be small and gutless, but if you're desperate for a slide on a longboard, you could have a look.
Then we're back to poor conditions for the rest of the run. The swell does build a little on the 24th and 25th, hitting 5 ft from the southwest and west, pushing the energy up to 169 and 290 (moderate wave energy), but the wind is messy – cross-shore and light, so it won't be clean. It's still too small and poorly aligned to get excited about.
Honestly, for a river-mouth setup like Crantock, this kind of blank run is normal. It's a sheltered spot and needs the right combo to fire. Keep an eye on the forecast; it tends not to stay poor forever, but for now, the surf is not worth the wetsuit.
Rusty.

Information about the Crantock Surf forecast
The above surf forecast table for Crantock provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Crantock can be found by selecting the local surf guide option on the grey menu. Our Crantock 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 (Crantock) 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 Crantock 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.
