The Lowdown
Alright folks, Rusty here. Let's look at what we’ve got for Crantock over the next couple of weeks. I gotta be straight with you—it's a tough run. The whole sixteen days is a bit of a write-off for good surf, not a single standout session in the lot. We're looking at a blank run here, which is more normal for a sheltered spot like this when the winds and swell just don't line up.
The first week is a real grind. From Tuesday the 18th of August through the weekend, it's just messy. We start off with a 5ft on Tuesday morning, but it's a weak, short-period windswell (combined energy 176) with a fresh cross-onshore wind. It's lumpy, choppy, and just poor. Wednesday and Thursday bring a bit more size—up to 7ft on Thursday morning with moderate energy (654)—but the wind is either onshore or cross-onshore, so it's all blown out. The water temp is a touch warmer than normal at 66°F.
Friday the 21st through Sunday the 23rd sees the swell drop right off. We're looking at knee-to-waist high slop, mostly under 3ft, with tiny, weak energy. A few rain showers around too. Not worth paddling out for.
There’s a period from Monday the 24th to Tuesday the 25th that's interesting in theory. Monday morning goes glassy, with a slight 1.0ft groundswell from the west (9-second period), but it's only got 23 units of energy. Later on Tuesday the 25th, we get a spike with 5ft from the west, a long 10-second period, and a clean cross-offshore breeze, giving us moderate energy (369). That’s the best of the bunch, but still just a "poor" call overall.
The second week gets a bit more serious in size, but not quality. From Tuesday the 1st of September onwards, we see some solid swell—8ft with big combined energy (857 by that Tuesday afternoon). But the wind is howling onshore from the NNW at 25 mph. At that size, with that wind and a beach setup, this looks more interesting for kite surfing than paddle surfing. It's only for experts, and even then, it'd be a battle.
So, stick a pin in this one. The only flicker of hope is that Tuesday the 25th morning and afternoon window with that clean, cross-off breeze and a bit of waist-to-chest high swell. It won't be epic, but it'll be the most user-friendly session. For the rest, forecasts can change, but right now? We wait.
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.
