The Lowdown
Alright, let’s get into it. Looking at the full 16-day picture for Constantine Bay, and I’ll be honest with you—it’s two completely different stories. The first week is a write-off, but there’s a solid window in the second week that’s worth planning around.
Right now, through the 20th, it’s ugly. Swell is running from 5ft to 7ft, but the wind is ruining every session. It’s cross-onshore, onshore, and lumpy. No two ways about it. The combined wave energy is moderate, readings from 407 to 968, so there’s push, but it’s messy. Periods are all over the place, from short 7-second wind slop to some 13-second groundswell, but the surface is so chopped up it won’t matter. Skip it.
Things start cleaning up on the 21st. Monday morning, the swell drops to 3ft from the W with a 12-second period, and we get that magic word: glassy. SE wind at 3 mph. Energy is weak at 235, but it’s clean. Not a standout, but it’s a start.
The 22nd is similar, 3ft W at 10 seconds, glassy again in the morning. Still small, but clean. Good for a longboard.
Now, the real highlight is further out, so pay attention. Wednesday the 23rd morning is the best of the whole run. Swell pushes to 4ft from WNW with a 14-second period, and the energy jumps to 867—that’s solid, moderate-to-strong. Morning is glassy with a NNE wind at 3 mph. This is the one to circle. Constantine Bay (Cornwall) is a beach and reef setup, and with this longer period groundswell, the reef sections could be fun. At 4ft, it’s still manageable for intermediates, not too big. The afternoon gets a bit iffy with a light cross-onshore and swell up to 6ft, but the morning is the magic window.
After that, the 24th and 25th are also worth your time. The 24th is smaller, 4ft WNW at 12 seconds, clean with a cross-off ESE breeze in the morning. The 25th is the other standout: 4ft WNW with a 13-second period, and a clean cross-off SSE breeze all day. Energy is at 537 in the morning, solid moderate. This is the kind of clean, lined-up surf that makes you want to clear your schedule.
The 26th drops off, 3ft in the morning, still clean, but the afternoon gets ordinary. From the 27th on, it fades hard. We’re down to 1ft to 3ft, and the wind swings to a strong cross-off ESE, but the swell just dies. Energy readings from 51 to 240 show it’s weak. You’ll be floating more than surfing.
Water temp is about average for this time of year. A shorty or 3/2 will do.
So, to sum it up: the next week is a loss. Don’t bother. The best bets are clear—Wednesday the 23rd morning for the biggest, cleanest swell, and Friday the 25th for quality clean waves. Those are your standouts. The rest of the second week is small and fading. Patience is key, but when it turns on, it’ll be worth it.
Rusty out.

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.
