The Lowdown
Alright folks, Rusty here. Let’s take a good look at what’s happening at Crantock for the next couple of weeks. I’m not going to beat around the bush – we’ve got a long, tough dry spell to start with. There is absolutely no surf worth paddling out for from Monday the 17th of August all the way through to Monday the 31st of August. That’s a proper two-week gap with nothing on offer. The river mouth is just not cooperating, with messy onshore winds and choppy conditions killing any chance of a wave. It’s one of those stretches where it’s normal for the area.
Now, here’s the only real light at the end of the tunnel. The morning of Tuesday the 1st of September is our one shot. We’ve got a solid 8.2ft swell rolling in from the west with an 11-second period. That’s a nice groundswell, carrying some serious energy – you can feel it in that combined energy reading of 1895. The wind is coming from the SSW at 19 mph, which is a clean cross-offshore breeze. That’ll keep the surface glassy and make paddling out a bit easier with those longer gaps between sets. The water temperature is sitting at 65.7°, which is a touch warmer than normal for this time of year, so that’s a little bonus for the skin.
Now, a word of caution: this swell is right on the edge of being too big for beginners. At 8.2ft, it’s really for the experienced crew only. Crantock is a river break, sheltered from the west, and with this long-period groundswell, it’ll be breaking a bit too straight for the beach but should line up nicely in the river mouth. The crowds are often here, so expect some company if you’re out there. The setup is more interesting for paddle surfing than kiting with that offshore wind. Just keep in mind this is a long-range call, so while it looks promising, the forecast can shift. After Tuesday afternoon, the swell bumps up to 9.8ft with even more energy, but the wind swings cross-shore and it gets messier, so that morning window is your best bet.
That’s the only standout in this whole outlook. The rest is a write-off. But keep an eye on the charts – things can change.

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.
