The Lowdown

Alright folks, Rusty here. Let’s get straight into it.

To be brutally honest, the next 16 days are looking pretty grim for Crantock. There’s no standout surf on offer anywhere in this window. The forecast is littered with poor surf conditions, backed up by dirty wind directions and messy seas. We’ve got a long, painful gap right through from now until the very last day with nothing worth paddling out for. The only flicker of something useable comes right at the start, but even that is a stretch.

Thursday morning, August 20th, sees the biggest swell of the early period, with a 7ft west swell rolling in. But don’t get excited—the wind is howling from the WNW at 19 mph, straight onshore, trashing any chance of a clean wave. The water temp is sitting at 66°, which is a touch warmer than normal for this time of year. Combined wave energy is moderate at 718, but with that wind, it’s just a messy, blown-out washout. Not a surfer’s window.

We then hit a dead zone. From Thursday afternoon all the way through to the end of the month, conditions bounce between messy cross-onshore winds, tiny swells, and high winds. Friday the 21st through to the 31st offers nothing that’s even remotely surfable. Small 0.7ft to 2ft swells with long periods up to 14 seconds on the 23rd and 24th might look interesting on paper, but the energy is pitiful—reading between 29 and 36—and the wind is all wrong. It’s a total blank run.

The most notable event arrives on Saturday, August 29th. We get a proper pulse of energy—an 12ft west swell in the afternoon, with combined energy hitting a very strong 2290. That’s serious power. But the wind is firing from the west at 19 mph, cross-onshore, turning it into a lumpy, nasty mess. With that size and wind, this is expert-only territory and honestly looks more interesting for kitesurfing than a paddle session. You’d be mad to try and surf it on a standard board.

The first hint of clean conditions appears on Tuesday morning, August 25th, with a fresh offshore wind from the southeast at 22 mph. But the swell is a pathetic 1ft. Clean, yes, but unsurfable. That’s the story right through to the end of the forecast on Friday, September 4th—wind shifts briefly improve, but the swell stays small or, when it does pick up, the wind turns against us.

Bottom line: Crantock is locked into a long, poor run. There’s not a single recommended session in the entire 16 days. The forecasts can change, but right now, leave the boards in the shed.

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.
