The Lowdown
Alright, I'll be Rusty for a minute. Let's have a look.
So, truth be told, looking at this whole 16-day run, it’s a bit of a tough gig. The pattern is messy from the get-go with a lot of wind and lumpy conditions, and the consistent scorecards are pretty flat. We’ve got a gap of nearly two weeks before we see anything that might be worth a paddle. The first real standout doesn’t come in until Wednesday, September 2nd, and even that’s a "marginal" call. Before that, we’re looking at a lot of onshore and cross-onshore wind messing up the potential.
Let’s start with the early days. From Wednesday the 19th through to the start of September, it’s frankly poor. We’ve got moderate to fresh breezes from the west and northwest, creating a lumpy and choppy mess at Crantock. There’s some solid energy in the water around the 20th, with combined swell energy hitting 767 (moderate wave energy) on Thursday morning, but the 19 mph cross-onshore wind is just blowing it all out. Thursday afternoon is a little better at 648 (moderate wave energy), but still not clean. The swell drops off quickly after that, with tiny 0.6 ft to 1 ft waves over the weekend and into the following week, which is basically flat. Not much to get excited about.
There’s a small window around the 25th and 26th where the swell bumps back up. On Wednesday, August 26th, we see a 7 ft swell from the west with moderate wave energy (487), but again, it’s a westerly onshore wind, so it’ll be rough and poor. Not one to rush for.
Now, here is the one that stands out, though it’s a long way off. On Wednesday, September 2nd, the morning session at Crantock looks promising. The wind shifts to a light southerly, giving us clean, cross-off conditions. The swell is a solid 7 ft from the west-northwest, with a period of 8 seconds and very strong combined energy at 588. That’s a powerful wave. For a river break like Crantock, a 7 ft swell is serious. It’s going to be heavy and hollow. This is strictly for experienced surfers only; beginners, stay out of the water. The water temperature is a touch warmer than normal at 66°, which is nice, but that’s not the main story. The rideable, clean conditions paired with that punchy groundswell energy make this the only real highlight. It’s over a week away, so keep an eye on the forecast, but if that wind holds, it could be the best day we get.
The rest of the period into Thursday and Friday of that second week is much smaller and messier again, with the west winds returning. So your only real chance is that Wednesday 2nd September morning.
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.
