The Lowdown
Right then, let's have a look at what's on the table for Crantock over the next couple of weeks. I'll be honest with you, it's a bit of a rough start. We've got a solid run of swell coming in, but the wind is just not playing ball for most of it, making for pretty ordinary conditions.
For the first week and a half or so, we're looking at a lot of cross-shore and onshore winds, mostly from the west and northwest. The swell hangs around between 3ft and 8ft, nothing too crazy, but that wind makes everything lumpy and choppy. The combined energy in the water is moderate to strong, hitting between 149 and 843 (moderate to strong wave energy), so there's plenty of push, it's just not clean. You'll see a few days in there where it's just messy. Not the kind of stuff you want to be paddling out into unless you're after a fight.
Then, around Wednesday the 23rd, we finally get a bit of a turnaround. The wind swings around to the southeast, going offshore. That's the key. On the morning of the 23rd, we get a clean 6ft swell from the west with a short period of 7 seconds, and the conditions are labelled "clean" and "surfable". It's not world-class, but it's a start. The real standout, and the one I'd mark on your calendar, is the afternoon of Monday the 23rd of September. We've got a 7ft westerly swell, a gentle offshore wind from the southeast, and the model is saying "expect good surf conditions". That's the best call in the whole run. The water temperature is running about 3° warmer than average at 64°, so a little extra warmth in the water for that session.
After that, the offshore winds hang around for Thursday the 24th, but the swell drops back to 4-5ft, and the wind gets a bit stronger, so it's less appealing. Then it's back to messy conditions with onshore winds for the rest of the period into the second week.
So, to wrap it up: don't bother for the first week and a half. The only real, proper standout is the afternoon of Monday, 23rd September. It won't be huge, but it'll be clean and fun. Get on it.

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.
