The Lowdown
Right then, let’s have a look at what’s on the table for Crantock. It’s a river mouth, sheltered spot, beginner-friendly when it’s working, but honestly, the next couple of weeks are looking pretty grim. There’s a real dry spell coming our way.
We’ve got no proper surf to speak of until we’re well into the first week of September. That’s a solid gap of over a week with nothing worth paddling out for. The water temp is sitting at 65°, which is a touch warmer than normal for this time of year, so at least it’ll be pleasant sitting out there doing nothing.
Things finally start to look a little more interesting on the Thursday morning of the 3rd of September. We see a jump in swell to 6 ft from the west, with a moderate wave energy reading (414). It’s still only rated as marginal, but it’s the first sign of life. The wind is a gentle cross-shore, keeping things with a slight chop but not completely blown out. The break faces Crantock, so that westerly swell is wrapping in.
Friday the 4th keeps the same sort of size, with 6 ft to 6 ft from the west, but the wind swings to a cross-onshore flow, making it choppy and lumpy. Not great, but there’s energy in the water with readings up to (459).
Now, here’s where it gets interesting for the more experienced crew. On Saturday the 5th of September, we get a proper groundswell from the west-northwest. Swell height is 6 ft, but the period stretches out to 11 seconds – that’s proper groundswell energy. The combined energy jumps to a strong 705. The wind is a cross-offshore from the south-southwest, keeping the surface clean. This is the standout of the whole period. That longer-period swell will wrap into the river mouth nicely, but just know that at a beach or river break, a long period like that can make it break a bit straight. For the experienced surfer, this is the one to circle. That swell size over 5 ft is pushing it for beginners though.
The rest of the run into the second weekend is downhill again. By Sunday the 6th, the swell drops back to 3 ft from the west, with strong onshore winds ruining the surface. Anything after that is not worth a mention.
So, to wrap it up: a long, quiet start, then one window of promise on Saturday the 5th of September. That’s your best bet, but it’s a long way off and forecasts can change. Keep an eye on it.

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.
