The Lowdown
Alright folks, Rusty here. Let's have a look at what's on offer for the next couple of weeks.
To be straight with you, this is a tough stretch for Crantock (Cornwall). The whole 16-day window is a bit of a write-off for a decent paddle. The swell is there at times, but the wind just won't play ball, keeping things messy and unsurfable. The real kicker is that the river mouth setup here is sheltered, and the optimum swell direction is west, but we're getting a lot of onshore and cross-shore wind from the wrong angles, which chops everything up. The first real glimmer of anything half-decent doesn't come until Sunday the 20th of September, but even that is marginal. We've got a week of poor conditions before that.
Looking at the first part of the period, starting Sunday the 13th, it's a no-go. We've got a cross-swell from the west around 5 ft, but with a 12 mph cross wind, it's just a lumpy, choppy mess. The combined energy is moderate (448), but it means nothing with that wind. The water temp is 64°, which is a touch warmer than normal for this time of year, but you won't be in it for long. This pattern of poor surf continues right through Monday and into Tuesday the 15th. Tuesday sees a jump in size, with 7 ft of onshore wind and a short period of 8 seconds, but the wind is fresh onshore, so it's blown out. This continues into Wednesday the 16th with 6 ft and more onshore wind, giving moderate wave energy (821). Thursday the 17th is the same story – 8 ft, but onshore wind, short period, and messy. Friday the 18th is a mess with a 25 mph cross-wind.
The one day that might offer a chance is Sunday the 20th of September. Early morning we see a cross-offshore wind from the SSW at 12 mph, which will clean things up. The swell is 5 ft from the WNW with a 10-second period. The combined energy is a solid 531. It's only a marginal call, but it's the best of a bad bunch. The tide might be a factor, and it's only a '1' out of 10, but if you're desperate, that dawn patrol could be worth a look for a few clean ones.
After that, it's back to poor conditions through the next week. We get a run of clean, cross-offshore winds from the 24th to the 27th, but the swell drops right off to nothing – 1 ft to 2 ft. There's no energy in the water (combined energy in the 30s and 40s). It's flat. The morning of Sunday the 27th is glassy, but again, only 2 ft of weak, useless swell. Then the wind comes back onshore hard that afternoon.
So, the bottom line is: save your energy. There's one marginal morning on the 20th, but that's it. The rest of the 16 days is a write-off. It's one of those blank runs that happens. Forecasts can change, but as it stands, I'd be looking for other hobbies for a couple of weeks.
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.
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.
