The Lowdown
Right, let’s have a look at what’s on the cards for the next couple of weeks. The river mouth at Crantock is our only spot on the radar, but honestly, folks, it’s a tough stretch. The water’s sitting at 65°F, which is a touch warmer than normal for this time of year, but that’s about the only nice thing I can say.
We kick off the outlook on Sunday the 30th of August, but don’t get your hopes up. The swell is there at 5ft from the WSW with a 9-second period, and the combined energy is moderate (367), but a strong cross-off wind from the SSW at 19 mph is making a mess of it. The report says poor surf conditions, and it’s a zero out of ten. The afternoon only gets worse with rain showers, a cross-shore wind, and lumpy chop.
Monday the 31st sees a big jump in size – 10ft from the W, with a 9-second period and massive energy (1386). That’s expert-only territory, but the wind is onshore and strong. It’s blown out. The whole first week, right through to Saturday the 5th of September, is a write-off. We’ve got onshore winds, cross-shore chop, and consistently poor conditions. The swell fluctuates, but the wind just ruins it every time. There’s a brief moment on Saturday morning with a 5ft swell from the W at 11 seconds, but it’s cross-on and choppy.
The first real glimmer comes on Sunday the 6th of September. The swell has dropped right off to 2ft, but the wind swings to the SSE at 16 mph, blowing offshore. The water goes clean. The only problem is the wave energy is weak (82), and the period is a short 6 seconds. It’s tiny, but it’s clean. If you’ve got a log, you might get a few ankle-biters.
Now, Monday the 7th of September is the one standout in this whole outlook. The swell picks up to 5ft from the W, with a very long 12-second period – that’s proper groundswell energy. The combined energy is moderate (692). The wind is light from the SW at 9 mph, giving us a gentle cross-shore with only slight chop. The report says it’s marginal, but compared to everything else, this is the best we’ll see. The long period means better shaped waves, but at a river mouth, it might break a bit straight. Still, it’s the only session worth paddling out for.
After that, it’s a long, slow fade. From Tuesday the 8th right through to the end of the outlook on Monday the 14th of September, the swell drops and the wind stays onshore or cross-on. The 14th has clean conditions with a light cross-off breeze, but the swell is a pathetic 1.0ft with bugger-all energy (16). There’s a slight chance on Saturday the 12th during the morning with a 3ft, 11-second period swell and clean conditions, but it’s weak.
So, to be brutally honest, the only session that’s even worth a look is the morning of Monday the 7th of September. It’s not perfect, but it’s the best we’ve got. The rest of the time, you’re better off checking the forecast again in a few days.

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.
