The Lowdown
Alright, listen up. Rusty here, and I'm looking at Crantock for the next couple of weeks. To be honest, it's a rough go. The forecast is a mess of onshore wind and sloppy surf, so don't plan any holidays around it.
We're in for a long, dry patch right from the start. From now until the 25th of August, it's pretty much a bust. The wind is mostly cross-onshore, the swell is short-period and lumpy, and the scores are pathetic. You'll be battling a choppy mess, not riding waves. There's a tiny window of cleaner conditions on the morning of the 24th with a light offshore wind, but the swell is a pathetic 0.3m. It's a total grind.
The first real sign of life – and I'm being generous – pops up on the morning of Tuesday the 25th of August. The wind turns cross-offshore from the SSE, and the swell jumps to 2.3m from the WSW. That's a serious size, with a combined energy of 845 (moderate), and it's a handful. For a river mouth like Crantock, that's for experts only. Beginners, don't even think about it; 2.5m is the limit, and we're close. The plus side is it's clean, but it's a marginal call with questionable tides.
We get a few more days of average, onshore junk after that, but the morning of Thursday the 27th of August has a little something. The wind goes glassy, dead calm, which is a huge plus. The swell is 1.4m from the WSW, so it's a manageable size, but the period is short at 7 seconds. The combined energy is 264 (moderate), so there's some push. It'll be surfable, but nothing special. Still, a glassy morning at Crantock is always worth a look.
The last little highlight is the morning of Saturday the 29th of August. Another glassy morning with calm winds, and a 0.9m swell from the SW. The energy is low (119), but it'll be clean. Again, very ordinary waves, but the clean conditions will make it feel a bit better.
So, bottom line: don't get your hopes up. There's no standout session. The best bet is to check the morning of the 27th for that glassy, clean 1.4m, but keep your expectations dialed way back. The water is running a touch warmer than normal for this time of year, at 19°.
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.
