The Lowdown
G’day, Rusty here.
Alright, let’s be straight with you—this 16-day window is a tough one. We’ve only got one half-decent window at Crantock, and it’s way off in the distance. The entire first week and a half is a write-off thanks to messy, blown-out conditions and onshore slop. Don’t even bother looking at the water until Saturday the 5th of September.
That Friday the 4th is still a complete mess—strong cross-shore and cross-onshore winds up to 28 mph, with lumpy 6 ft to 7 ft swell. Not worth a look.
But then, Saturday the 5th of September is where it gets interesting. That morning, a tiny 3 mph east breeze bumps in, giving us clean conditions at Crantock. The swell is a solid 5 ft out of the west with a 11-second period (good groundswell), and the combined energy is moderate at 521. It’s a river break, fairly consistent, and as a beginner-friendly spot, it’ll be clean and fun for a longboard or a foamie.
Then Saturday afternoon really stands out. The wind swings offshore from the southeast at just 6 mph—absolutely glassy. Swell jumps to 10 ft out of the west-southwest, but the period drops to 8 seconds, so it’s a bit of a windswell lump. Still, with that offshore wind and a combined energy of 1186 (strong wave energy), it’ll be a handful but rippable for anyone with some experience. That 10 ft is too big for beginners though—this one’s for the crew who can handle it.
The water temperature is 65°F, which is a touch warmer than normal for the time of year—a nice little bonus for the session. Crowds are likely here as it’s often busy, but with conditions that clean, it’s worth sharing the lineup.
After that brief window, Sunday the 6th onwards falls back into messy cross-shore winds and lumpy chop. Swell hangs around 6 ft to 4 ft, but the wind kills it. From the 7th through the 11th of September, it’s all onshore or cross-onshore junk—periods around 8 to 10 seconds but the wind just ruins any chance of clean faces.
So here’s the takeaway: you’ve got a long dry spell until Saturday the 5th of September. That’s your one real shot. Saturday morning for the mellow crew, Saturday afternoon for the rippers. After that, it’s back to waiting.

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.
