The Lowdown
Alright folks, Rusty here. Let’s get into it. The next sixteen days are looking pretty bleak around here, to be honest. We’ve got a long stretch of nothing really worth paddling out for, but there might be a flash in the pan right at the tail end of the window.
The first real chance for a surf kicks off on the 21st of August. Up until then, we are staring down a wasteland. From now, right through the 12th, 13th, 14th, 15th, 16th, 17th, 18th, 19th, and 20th, it’s basically flat or blown out. We’re talking over a week of poor conditions at Crantock. The swell is tiny, the period is short, and the wind is mostly onshore or cross-shore, making a mess of things. It’s the kind of stretch that has you checking your gear just to remember what it looks like. Water temp is about average for this time of year, no anomalies to speak of, so that’s not the issue.
Now, the 21st of August – that’s a Friday morning – things suddenly look interesting. Crantock, being a river mouth, can handle a bit of a punch, and we’ve got a solid 6ft swell rolling in from the WNW. The period is short at 7 seconds, so it’s windswell, not groundswell, but the combined energy is strong at 411. That’s a decent push of water. The wind is light and offshore from the ESE, so it should be clean. This is the standout of the whole window. It’s not huge, but for the size, it’s the cleanest we’ll see. By the afternoon, the swell bumps up to 7ft from the W, still with light offshore SE wind (598 energy), but that’s getting into the territory where it’s a bit much for beginners. For anyone comfortable, Friday afternoon could offer some punchy, clean river-mouth peaks. The wind turns on Saturday, though, so this is a one-day wonder.
After that, it’s all downhill again. Saturday the 22nd goes back to choppy onshore garbage, and the rest of the outlook fades into small, wind-affected slop. So, if you’re keen, mark your calendar for the 21st. That’s your shot.
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.
