The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s coming up for Crantock.
To be straight with you, the next ten days or so are a bit of a struggle. The wind is mostly onshore or cross-onshore, and the surf quality is pretty ordinary. There’s a run of poor conditions from now until the middle of the month, with only a few glimmers of hope. The water temperature is sitting at 65°, which is a touch warmer than normal for this time of year, so that’s nice for the skin.
The first real standout I can see lands on Tuesday the 15th of September. The morning kicks off with a clean 3ft swell from the west, with a period of 11 seconds, and a gentle offshore breeze from the southeast. The combined energy of all swells is moderate (227). This is a proper groundswell, and with that offshore wind, the waves will be clean and lined up. The afternoon is even better with 4ft and a moderate offshore breeze, giving you clean, surfable waves. The crowd factor here is "often", so expect some company, but it’s a river mouth break, so it can handle a few. The swell direction is west, which matches the optimum for this spot.
Looking further out, the next highlight is on Saturday the 19th of September. The morning is glassy, dead calm, with 3ft of swell from the west-northwest at a 10-second period. The combined energy is moderate (252). This is a rare treat – flat calm and clean. It’s a small wave, but for a longboard or a funboard, it’ll be a dream. The afternoon gets a light cross-onshore breeze, so the morning is definitely the window.
Then, on Monday the 21st of September, we get a gentle offshore breeze from the east-southeast with 3ft of swell from the west at a 10-second period. The combined energy is moderate (179). This is a clean, gentle session. The following morning, Tuesday the 22nd, looks similar with a light offshore breeze and 3ft of swell. Again, small but clean.
There is a bigger pulse of energy on the 23rd of September, with a 3ft swell from the west-northwest and a very long period of 14 seconds, giving a combined energy of 448. That’s moderate to strong energy. But the wind is cross-onshore, so the quality will be compromised. It’s not a standout.
So, for the whole 16-day window, the best on offer is Tuesday the 15th of September for the best combination of size, clean wind, and decent period. The Saturday morning glass-off on the 19th is a real close second for the pure clean conditions.
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.
