The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Crantock over the next couple of weeks.
Right off the bat, I gotta be straight with you – this is a lean stretch. The entire 16-day window is a bit of a write-off for proper surfing. We’ve got a long run of days where the conditions just aren’t coming together. The swell is small and weak, and the wind is almost always onshore or cross-onshore, leaving the waves choppy and messy. There’s no real standout window, and the data shows a whole lot of "poor surf conditions" across the board.
The water temp at Crantock is running at 66°, which is a touch warmer than normal for this time of year, so that’s a small comfort if you’re just going for a paddle.
Let’s walk through it. The first few days, from Saturday the 15th through Monday the 17th, we’re looking at weak swell around 2 ft to 3 ft from the W, with periods around 7 to 8 seconds. The wind is blowing from the N and NW, making it cross-onshore and choppy. Combined swell energy is barely scraping into the low hundreds or even below – just 117 (ft) on Saturday morning, dropping to a paltry 35 (ft) by Sunday afternoon. Not worth getting wet.
Tuesday the 18th and Wednesday the 19th are more of the same: 3 ft of weak, short-period W swell, but the wind is still on it from the WSW or WNW, and the energy figures are low at 95 (ft) and 131 (ft) respectively. A bit of light rain on Tuesday doesn’t help the vibe.
Now, Thursday the 20th sees a bit of a bump in size – swell hits 6 ft from the W – but the period is still short (8 seconds) and the wind is a fresh 19 mph cross-onshore. The energy jumps to 480 (ft), but it’s just a messy, lumpy, blown-out mess. That’s too big for beginners and not clean enough for anyone else. Friday the 21st is similar, with 4 ft to 4 ft swell and energy in the 200-300 (ft) range, but still cross-onshore winds. It’s a no-go.
The weekend of the 22nd and 23rd drops back to tiny surf – 1 ft to 2 ft – with a bit of a longer period on the 23rd (11 seconds), but the wind is all over the place. There’s a brief moment on Sunday morning the 23rd with a fresh offshore from the E, but the swell is only 1 ft, so it’s clean but flat. The energy is just 93 (ft). You’d be better off with a longboard and a lot of patience.
The following week, from Monday the 24th onward, brings a new swell from the N and NNW, but with it comes strong winds. Monday the 24th has 6 ft to 6 ft of short-period N swell, but a 25 mph cross-onshore wind makes it a total mess – energy is 249-294 (ft), but it’s more of a kite-surfing setup than a paddle-surfing one. Tuesday the 25th through Wednesday the 27th drops back to 1 ft to 4 ft, still with onshore to cross-onshore winds from the NNW. Choppy, lumpy, and not worth the effort.
Finally, there’s a glimmer on the last few days – Friday the 28th and Saturday the 29th. The swell is tiny, only 1 ft to 2 ft from the W, with periods around 8 to 9 seconds, but the wind finally goes light and offshore from the SE and ESE. The energy is low – 32 (ft) to 58 (ft) – but the conditions are clean. If you’ve got a log and you’re desperate, Saturday morning the 29th could give you a few glassy, knee-high runners. Sunday the 30th also looks clean with cross-offshore winds from the E, but again, the swell is only 2 ft to 2 ft.
So, the cold truth is there are no good surf options in this 16-day window. The swell is either too small, too short-period, or blown out by onshore winds. For a spot like Crantock, which is a river mouth and fairly sheltered, a blank run like this is more normal than you’d hope. The breaks are fairly consistent here, so it tends not to stay poor for long, but this forecast is a dud.
If you’re a kite surfer, the days with stronger wind and bigger, choppier waves (like Thursday the 20th and Monday the 24th) might look interesting, but for a paddle surfer, it’s a hard pass.
Stay patient, lads. The surf will come back.
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.
