The Lowdown
Alright, let’s get stuck in. Constantine Bay has been on a bit of a promise this past week, and honestly, it’s been a frustrating run for most of it. We’re looking at a real dry spell to start, so don’t get your hopes up for the next few days.
The opening of this window is a no-go. Through the 24th and into the 25th, there’s barely a ripple. We’re talking about ankle-slappers of 0.6ft to 2ft, and even though the mornings are clean with that offshore breeze, there just isn’t enough energy to push a surfboard. The combined energy is weak, in the 17 to 63 range, so it’s flat, plain and simple. The water temp is 65°F, which is a touch warmer than usual for this time of year, but it won't make up for the lack of waves.
We stay in the doldrums for a few more days. There's a slight bump to 3ft on the 27th, but it’s messy and short-period. Thursday afternoon brings a bit more size, around 3ft, but it’s onshore and choppy, and the score is still a zero. We’re looking at a long, flat stretch here, with a few hours of clean, glassy conditions on Friday the 28th morning, but the swell is still only 3ft and weak. It’s just not enough. You’d be fighting for a gutless wave.
The weekend is where it goes properly wrong. Saturday the 30th sees some bigger swell push in, but it’s all wind and rain, and the energy is just a mess. Sunday the 31st is a big one, with a solid 10ft of west swell pumping in, but it’s marred by strong, onshore winds. The combined energy jumps to 2206, which is strong, but the quality is shot. The beach and reef at Constantine will be a washing machine, closing out and blown out. Don't even think about it. This looks more interesting for the kite surfers than the paddle crew.
The first week of September is a write-off. The surf stays onshore and lumpy, or just poor. Swell hangs around the 3ft to 6ft range, but the wind and short periods keep it ugly. By the 4th and 5th, there’s more size, up to 6ft, but it’s accompanied by fresh cross-onshore winds and lumpy conditions. The energy is moderate to strong, but it’s all for nothing.
Then comes the real tease. On the 7th of September, over a week away, the forecast shows a proper, groundswell pulsing in. We’re talking a massive 15ft of west swell with a very long 17-second period. The combined energy is huge, over 10,000. This is the standout of the entire window. But here’s the problem: the wind is onshore. It's a big, powerful, and potentially dangerous wave. This is strictly for experts only – over 8ft is big territory, and a 15ft groundswell on a beach-and-reef setup can be a beast. This is promising, but it’s a long way off, so I’d take it with a pinch of salt right now. We’ll have to see if the wind backs off. If it does, Constantine Bay could be absolutely firing, but if it stays onshore, it’ll be a close-out fest for the kamikazes. There’s a slight letdown on the 8th, with 8ft and cleaner conditions, but it's still out of the average surfer's league.
So, there you have it. A long, drawn-out flat spell, followed by a week of messy, blown-out conditions, and then a potential monster at the end that will likely require a bigger pair of balls than most. Don’t box this one in your diary just yet.

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.
