The Lowdown
Alright, let’s get into it. I’m lookin’ at Crantock, a river mouth setup that’s usually pretty sheltered, and the pick for beginners when it’s on. The water’s runnin’ a touch warmer than normal for this time of year, about 66°F, which is a degree or so above average.
Right now, there’s a long stretch of pretty ordinary conditions. From Wednesday the 19th of August right through the rest of the month, it’s mostly poor with gnarly onshore winds, chop, and lumpy lines. The energy’s there at times, like on Thursday the 20th with a 7ft west swell and a 9-second period, and combined energy of 718, but the wind is straight onshore at 19 mph, so it’s messy. You’ll see a few days with clean cross-off winds from the east from the 24th to the 26th, but the swell’s barely a ripple, 0.7ft to 2ft, with combined energy down in the teens and twenties. That’s not worth paddling out for.
The first flicker of hope comes on Thursday the 27th of August. There’s a 3ft west swell, 10-second period, with clean offshore winds from the SSE at 12 mph. The combined energy’s 249, so it’s moderate, but the wave comment says “surfable waves but very ordinary conditions.” It’s a minor window, not a standout.
September opens with a bit more size but rough wind. On Monday the 31st of August and Tuesday the 1st of September, there’s a 6ft to 7ft west swell, 9-second period, and combined energy around 580 to 599, but the wind’s cross-on at 12-16 mph, making it choppy. Not the clean stuff you want.
The real standout, though, is Thursday the 3rd of September. That afternoon, Crantock will see a solid 8ft swell from the west-southwest, 9-second period, and combined energy of 1304 – that’s strong wave energy. The wind’s a fresh cross-off from the SSE at 19 mph, so it’ll be clean. That’s a big wave, more for experienced surfers, and the period’s short so it’ll be a bit lumpy. Still, it’s the best option in the whole outlook. Just keep in mind that’s a long way out, so forecasts could shift.
Otherwise, the 16-day window is pretty sparse. There’s a big gap of poor surf from now until the 27th, and then another quiet spell before the 3rd of September. It’s not a classic run, but that one Thursday afternoon could be a treat.

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.
