The Lowdown
Alright, let’s talk about Crantock. Honestly, the next week and a half is a bummer. We’ve got a long stretch of onshore breeze and weak, messy swell. Not much to get excited about until we get deeper into the run.
The first real chance of a paddle comes on the morning of Wednesday, August 12th. The swell is tiny, just 0.7 feet from the west, with a 10-second period. The energy is weak (104). But the wind is glassy, and for a river break like this, that’s the whole game. It’ll be clean as a whistle. The water temp is about average for the time of year. Don’t expect much, but it’s the first surfable wave in a while.
After that, it’s back to the same old story of onshore winds and choppy, small waves until the end of the week.
Then we get a big one. On Tuesday, August 18th, the swell comes roaring in. The morning has 8-foot waves from the west with a 9-second period, and the energy is a strong 1064. That’s a lot of water moving. By the afternoon, it’s pushing 10 feet from the west, with energy at 1509. That’s for experts only. The wind is onshore, though, so it’s going to be a messy, powerful beast. For a river break, that’s a washing machine. It’s honestly a better setup for a kite surfer than a paddle surfer.
The standout session, the one to circle on the calendar, is the morning of Thursday, August 20th. The swell has dropped to a much friendlier 4 feet from the west, still with a good 9-second period. The energy is moderate (268). The magic is in the wind: a light cross-offshore breeze from the SSE. That’s going to give you clean, lined-up waves. This is the only time in the whole 16 days where the wind and swell come together for something good. That’s your session.

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.
