The Lowdown
Alright folks, Rusty here. Let’s have a look at what Crantock has in store for us over the next couple of weeks.
I gotta be straight with you: the forecast for Crantock is grim. This is a sheltered river break that needs a specific westerly swell to get any kind of life, and for the first week and a half, we just aren’t seeing it. The wave energy is weak, often barely registering (15 to 72 on the combined energy scale), and the swell heights are mostly puny, under 3 ft. The winds are a mixed bag of onshore and cross-onshore, making the water choppy. It’s a real struggle. The only small window where it cleans up is Tuesday morning, August 11th, with a light offshore breeze from the SE, but the swell is only 1 ft. It’s clean, but there’s no power behind it. The rest of that first week is a write-off with poor conditions.
We do have a notable blip in the middle of the second week. On Wednesday, August 12th, the morning and afternoon both show surfable waves with a combined energy of 125 and 139, which is moderate interest. The swell is a clean 3 ft to 3 ft from the west, with a 10-second period. The wind is a gentle cross-offshore breeze from the east, so the conditions are clean. For a sheltered spot like Crantock, that’s about as good as it gets in this forecast. The water temperature is about average for this time of year, so don't expect any surprises.
The end of the run on Sunday, August 23rd, offers a tease. The morning is glassy with a light wind from the NNW, and the swell is 3 ft from the WNW with a 140 combined energy. That’s a clean, workable wave. But by the afternoon, a fresh 18 mph cross-onshore wind comes in and ruins it.
The real standout here is the whole of Wednesday, August 12th. The combination of moderate westerly swell with a clean cross-offshore breeze makes it the best chance for a decent paddle. The break is a river, so it’s not huge, but it’s the only day where the setup looks like it will actually produce a proper wave. Don’t expect to be threading the barrel, but for a beginner-friendly spot, it’s a couple of sessions of fun. The rest of the time, if you’re a kiter, it might be worth a look when the wind is up, but for us surfers, it’s a waiting game.
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.
