The Lowdown
Alright, let’s get into it.
Honestly, the next couple of weeks are looking pretty grim for a proper surf here. We’ve got a long stretch of poor conditions ahead, with a lot of cross-onshore wind and lumpy, choppy surf. It’s not going to be pretty for a while. You’re gonna have to be patient.
The first real chance of anything decent is on Friday the 21st. The morning is looking like the cleanest option we have for a while. It’s small, about 3ft, but the wind is light and cross-offshore, so it could be glassy. Energy is weak, only 195 units, but at least it’s surfable. The wave period is 8 seconds, so it’s a bit short, but for a wave this size, it might be okay. Crantock is a sheltered river mouth, so it can handle the less-than-ideal winds better than more exposed spots. But, honestly, it’s still pretty ordinary conditions. Don’t expect much.
Then we slide back into a real dead zone. From Saturday the 22nd through to Monday the 24th of August, the swell just dies off. We’re talking tiny, weak waves with nothing but cross-onshore winds, and even the energy readings are in the double digits – 119, then 97, then down to a pathetic 22. It’s flat, mate. Not worth paddling out. Don’t bother.
There’s a slight blip on Tuesday the 25th with a bit more energy (233 units) and a clean offshore wind in the morning, but the waves are still small, around 4ft. It could be a fun little morning session for a beginner or someone on a log, but it’s not going to be a standout. The period is a bit better at 10 seconds, so there might be a bit more push.
The late-week storms kick in from Wednesday the 26th, with strong winds hitting. By Saturday the 29th, the swell bumps up to 6ft, and the combined energy jumps to 550 units, which is a moderate push. But the wind is dead onshore, making it a lumpy, messy mess. With that size and conditions, it’s not looking like a friendly surf, and it’ll probably be a washing machine out there. This is more of a kite-surfing day than a paddle-surfing day, to be honest.
The following week just carries on the same theme. We see a bit of size around the 31st of August and the 1st of September, with 5ft, 5ft, and 6ft swells, and the energy is moderate. The winds are mostly cross-offshore or cross-shore, which is a bit better, but the overall quality is still poor. The waves are short-period and won’t have a lot of punch. It’s all a bit meh.
The only true standout in this entire 16-day stretch is Friday the 21st in the morning. It’s not big, but the clean, light offshore winds make it the most inviting option. The rest is a waiting game.
This is a tough run for the area, but this kind of flat, windy spell isn’t unusual. The charts can change, so keep an eye out, but as it stands, there’s nothing epic on the horizon.

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.
Crantock is 2 km (1 miles) from Newquay. If you plan a holiday in North Cornwall, look for hotels and other accommodation in Newquay. Newquay has rooms for a wide range of budgets as well as car hire and transport links.
