The Lowdown

Alright, crew, Rusty here. Let's be straight with you: the next two weeks at Constantine Bay are looking pretty grim if you're after a proper surf. We've got a lot of wind and messy conditions on the way. It's one of those stretches where you're better off saving your energy for something else.

The water is sitting at 66°F, which is a good few degrees warmer than normal for this time of year – that's a bit of a bonus if you're just having a splash about. The surf itself is just not there for a while. We're looking at a solid run of days where the quality is just too poor to get excited about. The wind is mostly onshore or cross-onshore, chopping everything up. There is some energy around, but it's not doing us any favors.

The first chance of scoring anything clean at Constantine Bay (North Cornwall) comes on the morning of Friday the 21st. It's small though, maybe 3ft of west swell at 8 seconds, and the energy is weak at 138. The wind will be a light cross-offshore breeze from the NNE, which will keep it clean, but it's really just a dribbler for a longboard. Not much to get your heart racing. Thursday the 20th sees a jump in energy to 600 by the afternoon, but a fresh cross-onshore wind ruins it.

The weekend drops right off. Saturday the 22nd has a tiny 1ft west swell, and Sunday the 23rd is nearly flat with a 0.7ft southwest groundswell. The period is long at 14 seconds, but there's no power behind it at all. The water will be clean, but you'd be hard-pressed to find a wave that stands up. It's a real weekend for the beach, not the lineup.

The following week stays pretty much the same – nothing worth calling in sick for. Monday the 24th is nearly flat and glassy early, but it's just nothing doing. We see a bit more swell push through mid-week, but the wind is all over the shop. By Thursday the 27th, it's small and westerly, with onshore breezes again.

Now, look ahead at your own risk. The last couple of days of August and into the 1st of September are where it gets serious. There's a big pulse of west swell on the horizon. The morning of Tuesday the 1st of September shows a hefty 8ft of west swell pushing up to 10ft in the afternoon. The wave energy is going through the roof, hitting a very strong 2066. But here's the catch – it's all wrapped in cross-onshore winds. At that size, and with that wind, Constantine is going to be a full-on, expert-only, lumpy mess. If it cleans up, it could be a proper session, but as it stands, this looks like it's set up more for the kitesurfers than paddle surfers. That’s just the way it’s looking.

So, to sum it up: the next week is flat and messy, and the big swell at the end of the window is too blown out to surf comfortably. It's a real barren run. But a place this consistent can turn around quick, so keep your eyes on the charts.

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.
