The Lowdown
G’day, this is Rusty. Look, I’ve been staring at the charts for Constantine Bay (beach and reef setup) and the next couple of weeks are a proper mixed bag. The first week is a bit of a grind with mostly small, weak swell and pretty ordinary conditions. There’s a nice pulse of energy building for Friday the 21st and Saturday the 22nd, but by Sunday it gets messy again. Let’s break it down.
Right now, Tuesday the 11th, it’s tiny – we’re looking at 1ft from the WNW with a short 8-second period. Combined energy is real weak (29). The wind is a cross-off from the SE, so the surf is clean but there’s just no power. Water temp is about average for the time of year. Don’t bother paddling out.
Wednesday the 12th, the swell bumps up a bit to 3ft from the W with a 10-second period, combined energy ticking up to 126 (moderate). Morning’s got a light NNE cross-off, so it’s clean, but the wave quality is only “very ordinary.” Afternoon turns cross-on from the NNW with small wind ripples. Still not great.
Thursday the 13th, swell holds around 4ft from the W with an 11-second period, combined energy moderate to strong (267). But the wind is a cross-shore from the NNW, so it’s a bit choppy. Not the day to get excited.
Friday the 14th, we’re down to 3ft from the W with a 9-second period. Morning has onshore wind from the WNW, and the afternoon gets a moderate cross-onshore chop. Weak and messy.
Saturday the 15th, 3ft from the W with 8-second period. Morning is clean with a cross-off from the N, but the energy is only moderate (149). Afternoon gets choppy with a 25 km/h NNW cross-on.
Sunday the 16th, it’s dropping fast – 2ft with a 7-second period. Not worth a mention, really.
Monday 17th through to Thursday 20th, it’s all small – between 1ft and 3ft – with a mix of clean mornings and lumpy afternoons. The combined energy mostly stays below 100 or just barely into three digits. Very average.
Now, here’s where it gets interesting. Friday the 21st of August is the standout. Overnight, a 6ft swell from the WNW with a 7-second period rolls in, and combined energy jumps to 411 (strong). The morning is glassy – calm conditions with a slight air from the SE. That’s going to be clean, punchy surf at low tide on the banks. By the afternoon, the swell bumps to 7ft from the W with an 8-second period, combined energy at 598 (strong), and a light SSE cross-off wind. Very good conditions for intermediate to advanced surfers. It’s a bit big for beginners at 7ft, but if you’ve got the skills, this is the pick of the whole forecast. Crowds are possible here – it can get busy.
Saturday the 22nd keeps the swell up around 7ft from the WNW (7-second period) in the morning, with strong energy (478), but the wind swings onshore from the WSW, so it turns into a bumpy mess. Afternoon is the same story with stronger WSW wind.
From Sunday the 23rd right through to Wednesday the 26th, the swell drops off hard – back to 3ft or smaller, with onshore or cross-onshore wind and very poor conditions. Not worth the wetty.
So, overall, you’ve got a long stretch of flat to weak surf until that one proper swell on Friday the 21st. If I were you, I’d circle that Friday morning – glassy, clean, 6ft WNW swell at Constantine. That’s the one to plan for. After that, the window closes fast. This is Rusty, signing off.

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.
