The Lowdown
Right then folks, Rusty here. Gotta be straight with you – this next couple of weeks at Constantine Bay is a real mixed bag of frustration and promise. We’re looking at a long, long stretch of messy conditions before things finally clean up.
The opening period is a write-off. From Friday the 11th right through to Monday the 21st, the onshore winds are just relentless. It's a solid block of cross-on or onshore breezes, churning up a chop that leaves the waves looking more like washing machines than surf. Sure, there's swell out there, with combined wave energy sometimes climbing into the moderate range (257 up to 669), but it’s all wind-battered and lumpy. You’ll see chest to head-high sets on Sunday the 13th (5 ft) with a nice 10-second period from the west and a clean offshore wind, but it’s a fleeting moment with marginal tides, and the afternoon reverts to slop. For a spot like this, when the wind is wrong, it’s just wrong.
Then, right at the tail end, there’s a glimmer. On Tuesday the 22nd, the whole picture flips. We're looking at a beautiful, clean morning with a light offshore from the northeast at 9 mph on about waist to chest-high swell (4 ft) from the west. The combined energy is a solid 312 – decent, not huge, but with that glassy feel you just have to wait for. The crowd factor here is listed as ‘sometimes’, so you might have company, but with conditions that clean, it'll be worth it.
The standout, if you can hold out, is Thursday the 24th. The morning session is where it’s at: a solid 6 ft of west swell, clean as a whistle with that cross-offshore breeze from the southeast at 16 mph. The combined energy hits a beefy 1055, which is a proper powerful groundswell. The period is a moderate 9 seconds, so it won't be too walled, but with that directional goodness and clean faces, Constantine will be showing its best side. After a solid ten days of rubbish, that morning is the one to circle on your calendar. Just be aware that the crowds are a possibility.
For the rest of that final week, the 26th looks clean but small, with just waist-high lines. You could get a longboard out, but the real quality has passed.
So, the long-range promise is there, but it’s a patient man’s game. The first ten days are a hard pass. The 24th morning is your golden ticket.
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.
