The Lowdown
Alright, grab a coffee and let’s talk about what’s ahead for Crantock (River). To be brutally honest, the next 16 days are a real mixed bag, and I’m not gonna sugarcoat it – the waiting is the hardest part. We’ve got a good stretch of nothing but poor conditions kicking off on Wednesday, 26 August, with a weak, short-period swell from the west. The swell is tiny, around 2ft, and the wind is blowing offshore from the SSE, keeping the surface clean, but the energy is weak (62). It’s a skunk session, to be honest.
The rough stuff continues through Thursday and Friday. The swell starts to build a little, but the wind is swinging to the SW and cross-shore, making for a lumpy, messy surface. The energy is still very weak for most of that time. By Saturday, 29 August, the swell is getting bigger – 6ft in the morning and 8ft in the afternoon – but the wind is howling with a strong breeze from the WSW, creating a messy cross-chop. The combined energy is picking up (362 then 1133), but the conditions are poor. This is more of a kite surfing show than a paddle session.
Sunday, 30 August, sees a cleaner swell (6ft, W, 10-second period) with a cross-offshore wind, but the energy is moderate (682). The chance of a thunderstorm is a buzzkill, but the surf might be the cleanest we’ve seen in a few days. Still, it’s not a standout.
The start of the new week, Monday, 31 August, and Tuesday, 1 September, bring a bigger swell (7ft), but it’s onshore or cross-onshore with a W wind, so it’s a choppy mess. The energy is strong (615, 573), but it’s not clean. The wind stays onshore for the next few days, keeping the quality low.
Now, here’s the one bright spot in the whole window. Friday, 4 September morning. The swell is a solid 5ft from the west with a nice 10-second period, and the wind is dead calm – glassy conditions. The water is about average for the time of year, nothing crazy. The combined energy is moderate (463). This is the only time the guidance says "expect good surf conditions". It’s a river break, so it can handle that long-period groundswell well, shaping up nice lines. But, it’s a river mouth, so it can get a bit fickle. Crowds are a possibility, but it’s a Friday, so you might get lucky. This is the only real window of quality.
After that, the wind kicks back in and the swell drops. The second week has a few flashes of potential, like the morning of Monday, 7 September, with a massive 12ft swell from the west and a clean cross-offshore wind, but the energy is extreme (2310). That’s expert territory, and it’s only a marginal call. The rest of the week is back to choppy, lumpy stuff.
So, in plain speak: hold out for the morning of Friday, 4 September. That’s your best bet. Everything else is either blown out, too small, or too raw. The river can be a magical spot, but it’s gonna need a lot of patience this time around.

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.
