The Lowdown
Alright folks, Rusty here. Let's have a look at what Constantine Bay has in store for us over the next couple of weeks. I'll be straight with you, this isn't going to be a classic run, but there might be a couple of windows if you're keen.
Right now, the water is feeling incredibly warm for this time of year, sitting about 3° above normal at 67°. That’s a proper anomaly.
We are looking at a long stretch of pretty average conditions kicking off. Sunday the 16th is a write-off with tiny, onshore slop. Monday the 17th and Tuesday the 18th see a bit more size, with the swell hanging around 3ft to 4ft from the WNW, but the onshore winds are just going to ruin it – messy, lumpy, and choppy. It's not worth paddling out for.
The week gets worse before it gets better. From Wednesday the 19th through to Friday the 21st, the swell jumps up a notch – we’re talking 6ft to 7ft from the west – but the onshore winds are strong, hitting 19 to 22 mph. The wave energy is moderate to strong (303 to 594), but the quality is terrible. It's going to be a washing machine. On Thursday the 20th, you've got rain showers to deal with as well.
We finally get a bit of a wind switch around Saturday the 22nd and Sunday the 23rd. The wind swings to a cross-offshore direction from the NE and N. The swell drops right back to tiny, pathetic 1ft to 2ft stuff from the north, and the period is super short (5 seconds). It’s clean, sure, but there’s just no power.
Monday the 24th and Tuesday the 25th are more of the same – clean but flat with wave energy barely registering (28 to 62). You'd be better off having a paddle on a sup than catching a wave.
The swell tries to rebuild around Wednesday the 26th and Thursday the 27th. We get some 4ft to 5ft swell from the west, and wave energy starts to creep back up (155 to 228), but the wind is mostly cross or cross-on, so it’s going to be choppy again.
Now, if you were hoping for a big finish, the last few days look wild but not surfable. On Friday the 28th, we’re looking at strong onshore winds (28 mph) and lumpy 5ft surf. Then Saturday the 29th brings the biggest, most powerful swell of the whole forecast – a 10ft west swell with a combined energy of 1366! That is serious, but the wind is howling onshore at 22 mph. Unless you are an absolute expert looking for a fight, this is going to be a brutal, blown-out mess. It looks more interesting for a kite surfer than a paddle surfer. By Sunday the 30th and Monday the 31st, it’s still big and onshore, so forget about it.
The Verdict: Honestly, there are no real standouts in this 16-day stretch. The conditions just never seem to align properly. The cleanest windows are the 22nd through 25th, but there’s no swell to ride. If you’re desperate, the best of a bad bunch looks like Wednesday morning the 26th at Constantine Bay. The swell is 4ft from the west with moderate energy (155), but the wind is a gentle cross-on, so it will be fairly choppy. It’s not good, it’s just the least bad option.
Stay tuned, things can change. 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.
