The Lowdown
G'day, Rusty here, and I've gotta be straight with you—this forecast is a bit of a tough one. For the whole 16-day window, Crantock is the only spot on the radar, and it's a real struggle. The water's sitting at 65°, which is a touch warmer than normal for this time of year, so at least you won't be freezing your backside off while you're waiting for waves that aren't really there.
Right, let's get into it. For the next week and a half, it's pretty grim. From Wednesday the 26th of August right through to around Saturday the 5th of September, the surf is just no good. The wind is often howling out of the west or southwest, creating a messy, choppy surface. The swell is there, but it's short-period junk, mostly under 9 seconds, and the combined wave energy is weak to moderate (between 42 and 794). The first real glimmer of hope isn't until Sunday the 6th of September. That morning and afternoon, we finally get a clean setup with a moderate offshore wind from the southeast, and a 6ft swell from the west with a 10-second period. The combined energy is a solid 518—moderate, but with good energy. This is your standout window. The offshore wind will groom the faces nicely, making it a great session for a beginner-friendly spot like Crantock, just be aware that crowds are often here. That swell is a bit short for a full-on groundswell, but it'll be clean and fun. Things then drop off quickly on Monday the 7th of September, with a smaller 5ft swell and a drop in quality, and after that, it's back to poor conditions through to the end of the forecast on the 10th of September.
So, in short, there's a big stretch of nothing from now until the 6th of September. The only real opportunity is that Sunday the 6th of September at Crantock with light offshore winds and a clean 6ft swell. Mark it in your calendar, but don't hold your breath for the rest of the run.
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.
