The Lowdown

Alright, surfers, Rusty here. Let’s be straight with you about the next couple of weeks down at Constantine Bay. It’s a bit of a mixed bag, and honestly, for a while there, we’re in for a pretty flat and messy run. But hold on to your boards, because there’s a serious pulse of swell trying to show up at the very end of the window – it’s a long way out, but it’s got some real potential.

Right now, and for the next few days, it isn't pretty. The water’s a warm 67° – that’s a solid 4° above the norm for this time of year, which feels more like a bathtub than the Atlantic. We’ve got weak, short-period swell rolling in, but the wind is all over the place. Friday the 14th and Saturday the 15th are a write-off – onshore and cross-shore winds, lumpy and choppy, with only about 3 ft of messy swell. The energy is weak, with combined swell readings around 102 to 129. It’s not worth getting wet for, to be honest.

Sunday the 16th drops off further, down to 2 ft, and the following Monday isn't much better. We’re looking at a real flat spell here, a few days where you’d be better off doing anything else. The swell direction is straight onshore, which just adds to the mess.

Things pick up a little around Tuesday the 18th as a new pulse of short-period swell arrives, but the wind turns onshore again, gusting to 19 mph, so it’s going to be blown out and sloppy. We see some more energy on Wednesday the 19th, with the swell reaching about 5 ft, but it’s coming from the WNW with a short period of 6 seconds and a cross-onshore wind. The combined energy gets up to 220, but it’s all surface chop. Not a classic.

The first real glimmer of hope comes on Saturday the 23rd. We’ve got a clean, glassy morning with a gentle offshore wind from the ENE. The swell is small, only about 3 ft, and the period is a poor 6 seconds, so it’s not going to have much push. But the conditions will be clean. The combined energy is a weak 93. It’s surfable, but you’ll be working for it. That afternoon we get a moderate offshore breeze, but the swell drops off.

The following days stay pretty small and wind-affected. The 24th brings strong offshore winds, which makes it clean but hard to paddle into, and the swell is tiny. It’s not until the very end of the forecast that things get interesting. On Thursday the 27th, we’ll see the swell start to build, hitting 7 ft in the afternoon, but the period is still short.

Now, here’s the one to keep an eye on. Friday the 28th. That’s when a serious, long-period groundswell is forecast to roll in. We’re talking a solid 16 ft to 18 ft swell from the west with a period jumping up to 12-13 seconds. The energy readings are massive – 7613 to 9075 – this is a powerful swell. The wind is looking cross-offshore, which would keep it clean, but with this much size and this kind of period, Constantine Bay, being a beach and reef setup, is going to be for very experienced surfers only. This is a heavy, powerful swell, well over the 8 ft mark, so it’s expert territory. And being a beach break, a long-period groundswell like this can break a bit too straight, making it tricky. Saturday the 29th will still have plenty of size, around 13 ft, but the wind turns more cross-shore and it starts to get lumpy.

So, to sum it up: the next week and a half is mostly flat or messy. Don't get your hopes up. But that Friday the 28th is the standout – a real winter-style slab of a swell, promising but a long way out. Keep an eye on the charts, because if that wind holds, it could be a day for the big-wave crew.

Stay stoked.

Rusty.

Information about the Constantine Bay Surf forecast

The above surf forecast table for Constantine Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Constantine Bay can be found by selecting the local surf guide option on the grey menu. Our Constantine Bay 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 (Constantine Bay) 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 Constantine Bay 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.

Constantine Bay is 7 km (4 miles) from Padstow. If you plan a holiday in North Cornwall, look for hotels and other accommodation in Padstow. Padstow has rooms for a wide range of budgets as well as car hire and transport links.
