The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer for Crantock over the next couple of weeks. Straight up, I’m not gonna sugarcoat it: the first week is pretty rough. We’ve got a solid run of onshore winds and messy conditions through to September 20th. The swell’s hanging around 5ft to 7ft, with combined wave energy mostly in the moderate range (hitting 427 to 936), but it’s all being blown out by fresh breezes from the west and northwest. This is more of a kite-surfing show than a clean paddle session. Not worth getting wet for.
Now, there’s a gap of no real action until we hit September 21st. That Monday morning, things finally calm down. We get a glassy, clear morning with a tiny 3ft west swell, period around 12 seconds. Combined energy is low at 235, so it’s not packing any punch, but for a river break like Crantock, that light offshore from the ESE and glassy conditions will make for some clean, user-friendly waves. It’s a beginner-friendly spot and fairly consistent, so if you’re just wanting to get out, this is your window. The water temp feels about average for this time of year.
The real standout, though, is shaping up for Wednesday, September 23rd. The afternoon session is where it’s at. We’re looking at a 6ft swell from the west-northwest, with a very long period of 14 seconds. That’s groundswell energy, and the combined energy is pumping in at 1058 – strong stuff. Winds go glassy, skies are clear, and the report calls for very good surf conditions. At 6ft, it’s a bit too much for total beginners, but for anyone who’s comfortable, this is the pick of the forecast. That long-period west-northwest swell lines up perfectly with the optimum direction for this sheltered river break. There’s potential for some real quality here.
After that, we get a few more clean days. September 25th, Friday, has a 4ft west-northwest swell with a 13-second period, clean conditions with a gentle offshore from the ESE. Combined energy is still solid at 609. It’s a good follow-up session.
The last few days of September and into the 30th see the swell dropping right off, with heights under 3ft and energy falling to below 100. The wind stays offshore, but there’s just not enough swell to get excited about.
So, to wrap it up: don't bother this week. Wait for the 21st for a glassy rehab session, but circle Wednesday, September 23rd. That’s the one. Glassy, strong groundswell, and the best conditions of the whole outlook. Promising, but you know how the long-range can be – keep your fingers crossed.
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.
Crantock is 2 km (1 miles) from Newquay. If you plan a holiday in North Cornwall, look for hotels and other accommodation in Newquay. Newquay has rooms for a wide range of budgets as well as car hire and transport links.
