The Lowdown
Alright, folks, Rusty here. Let's have a look at what the next couple of weeks have in store for us at Crantock. It’s a bit of a mixed bag, and honestly, we’re going to have to be patient.
The immediate forecast is pretty grovelly. We’ve got some swell, but it’s being blown out by strong westerly winds. It’s one of those setups where the energy is there, but the surface is going to be a mess. We’re talking onshore winds and lumpy, choppy conditions for several days. Not the kind of thing that gets you out of bed early.
This stretch of poor conditions looks set to run from Tuesday the 15th all the way through to the end of the weekend. We see a brief pulse of longer-period groundswell on Friday the 18th, with swell energy jumping up to (1095), but it’s all cross-shore and chopped up. Not worth the paddle.
Now, if you can wait, this is where it gets interesting.
The standout window is going to be Wednesday the 23rd and Thursday the 24th, but with a twist. Wednesday morning looks like the pick of the entire forecast. We have a fresh offshore breeze from the ESE, which should groom the faces nicely. The swell is still a bit small, around 4ft, but it’s from the WNW with a solid 13-second period. It’s a river break (Crantock), so the long period will help it focus and push in, and that offshore wind will make it clean. This is promising, but as it’s over a week out, we should treat it as a hopeful call rather than a certainty.
There’s also potential on the morning of Sunday the 27th. It’s looking glassy with a light southerly air, and a similar WNW swell at 4ft with a long 13-second period. The energy will be decent (660), and if the wind holds, that could be a great session. The afternoon looks to get blown out by a moderate NW onshore, so it’s a morning mission.
The water is a touch warmer than normal for this time of year, coming in at 64°, which is a small bonus. It’s a subtle thing, but you can feel it.
So, my honest take: there’s a lot of nothing for the first week, but Wednesday the 23rd and Sunday the 27th mornings have real potential. Don't get too excited about the big windswell in the middle; it’s a waste of energy. Patience, and you’ll be rewarded.
Stay salty.

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.
