The Lowdown
Alright, let’s have a proper look at what’s on offer for Crantock over the next couple of weeks.
Straight up, I’m not gonna sugarcoat it – the next week and a half is a write-off. A real dusty, frustrating run of tiny, wind-chopped slop. We’ve got a solid 11-day gap here where there’s nothing worth paddling out for. The wind is all over the shop, mostly onshore and cross-onshore, and the swell is just too small and weak to do anything with. The combined energy is mostly in the double digits, barely kicking into triple digits a couple of times, but even then it’s messy. You’d be fighting a losing battle.
The first flicker of hope comes on the morning of Friday the 28th of August. That’s a long way off, but it’s the only genuine standout in the whole run. The wind is light and cross-offshore, which will keep things clean. The swell fills in nicely, coming from the west at 6.6ft with a 9-second period. The combined energy jumps right up to 685, which is a proper solid pulse. For a sheltered river setup like this, that’s a decent push. It’s a bit on the bigger side for the absolute beginners, as it’s over 5ft, but for anyone with a bit of experience, that’s the day to circle. The water temp is about average for the time of year, so nothing wild there.
The afternoon of the same day is a bit of a letdown after that morning, with the swell dropping and the wind going cross-shore, making it marginal. After that, it looks like it’s going to get lumpy and messy again through the weekend.
So, the long and short of it is: you’ve got a long wait for a very short window. The Friday morning of the 28th is your one and only chance at something decent. Everything else is a hard pass. Patience, mate.

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.
