The Lowdown
Alright, let’s talk about Constantine Bay. It’s a beach-and-reef setup, and it’s very consistent, so it’s always got a shot at something. But to be honest, looking at the whole 16-day window, it’s a frustrating run. The water’s sitting right around average for this time of year, so nothing weird there.
The start is pretty flat. From Saturday the 8th of August right through until late on Sunday the 10th, there’s barely a ripple – just tiny, poor quality waves. Monday the 10th morning offers a glimmer, with a clean 1ft cross-off wind, but it’s weak and the period is a short 8 seconds, so the shape isn’t there. The combined energy is a measly 40 (weak). Not worth getting out of bed for.
We hit a bit of a lull again until the morning of Wednesday the 12th. That morning sees a jump to 3ft from the west, with a 10-second period, but the wind is howling cross-off at 25 mph. The energy climbs to 125 (moderate), but it’s messy and poor. Still no good.
Thursday the 13th of August is the first real standout. The morning brings 4ft of west swell, with a period of 11 seconds – that’s groundswell, and it’s got some push. The combined energy hits 275 (moderate). The wind is a light cross-shore, so it’s not clean, but it’s the best looking day in the first week. The waves will be a bit sectiony, but for an intermediate, it’s a go. But keep in mind, with the longer period, it might break a bit too straight for the beach, so look for a bank.
The next few days are a write-off, with onshore winds and dropping energy. Then Monday the 17th of August brings a pulse. The morning sees 4ft, and the afternoon hits 5ft, both from the west, with a cross-onshore wind. The energy is up to 310 (strong) in the afternoon. It’s messy though – lumpy and choppy. This is a powerful, reachy wave, but only for the experienced. The 9-second period is short enough to keep it manageable.
The biggest swell of the whole period hits on Tuesday the 18th of August. We’re looking at 8ft from the west-northwest, with energy reading 784 (strong) in the morning and 987 (strong) in the afternoon. That’s a lot of water moving. The wind is cross-on, so it’s ugly, but the sheer size will test the experts. This is not for beginners. For anyone looking for a tow-in or a big-wave session, this is the window. It’s a raw, powerful day.
After that, it drops back down. The very end of the run, on Saturday the 22nd of August, sees a 6ft west-northwest swell with a short 7-second period, and onshore wind, making it a windy, weak mess.
The absolute best of the lot is Thursday the 13th of August. It’s the most balanced day – decent size, good period, and the lightest wind. For a surfer, that’s the one to circle. The second standout is the big Tuesday the 18th, but only for the hardcore crew. The rest? It’s a classic summer run of poor conditions being masked by clean air. There’s a long gap of nothing from the 15th to the 16th, and then again from the 19th to the 20th. It’s a tough 16 days, but the swell is always trying to show up. It’ll turn.

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.
