The Lowdown

Alright, let’s get into it.

We’re looking at Constantine Bay here, a beach and reef set-up that’s exposed to the west. The water is sitting at 66°, which is about 4° warmer than usual for this time of year – that’s noticeably warm, you’ll feel it.

Honestly, the next week and a half is a bit of a write-off. The surf is small, the wind is messy, and the quality just isn’t there. We’ve got a long stretch of poor conditions from Tuesday the 11th right through to around the 19th of August. The waves are tiny, often under 3 ft, and the wind is either cross or onshore, making it choppy and uninviting. There’s a brief moment on Wednesday morning the 12th with a light NNE breeze and a clean 3 ft of swell, and Wednesday afternoon turns glassy with 3 ft, but the wave energy is still weak (126 and 139) and the conditions are described as “very ordinary.” Not worth paddling out for.

The surf really picks up from the 20th of August, but it comes with a catch. Thursday the 20th sees a solid 10 ft swell from the WNW, with a period of 8 seconds and a massive combined energy of 1228. That’s strong, powerful surf, but it’s also big and cross-onshore with a light breeze. The tide looks questionable too. This is expert-only territory – if you’re not comfortable in heavy, choppy, overhead waves, stay on the beach. The afternoon stays similar at 10 ft and 1130 energy.

The standout window, and the only one I’d really get excited about, is Sunday the 23rd of August. The morning shows an 8 ft WNW swell with a clean SE cross-off breeze, energy at 754 – that’s solid. But the afternoon is the real gem: 7 ft from the WNW, with a clean ESE offshore wind at 12 mph, and the conditions are described as “expect good surf conditions.” That’s a proper window. The swell is still big enough for intermediates, but with that offshore wind, Constantine Bay will be clean and well-shaped. Keep in mind the period is only 8 seconds, so it’s a windswell, not a long groundswell, but with the right wind it’ll still offer some fun, punchy waves.

After that, it tails off quickly. Monday the 24th and Tuesday the 25th are back to poor conditions, with onshore winds and lumpy, messy surf.

So, bottom line: get ready for a long flat spell, then a big, lumpy pulse mid-week, and your best bet is the afternoon of Sunday the 23rd at Constantine Bay. That’s the one to circle.

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.
