The Lowdown
Alright, it’s your local surf reporter Rusty here to guide you through the outlook for Constantine Bay (beach and reef). This spot is a classic exposed west-coast setup, usually picks up a lot of swell but it can get messy with the onshore winds. The water’s sitting at around 66°F, feeling a touch warmer than normal for this time of year.
Honestly, the next couple of weeks are a tough watch for quality surf. We kick off on Tuesday 18 August with some small, weak, onshore junk – 6-second period, moderate energy and messy conditions. Nothing to get excited about, that's a hard skip.
Wednesday 19 August stays average; the swell’s still short-period and the wind is howling from the west, blowing straight onshore again. Thursday 20 August brings a bit more size, swell hitting 7ft from the WNW with moderate to strong combined swell energy (654), but the wind swings cross-onshore, making it choppy and sloppy. Not really worth paddling out for.
We finally get a tiny window of light on Friday 21 August in the morning. It’s small, 3ft, with a period of 8 seconds but we get a cross-offshore breeze from the NNE, keeping it clean. It’s only marginal and worth a paddle if you’re desperate for a few small waist-high waves. The rest of the weekend gets shaky again.
Friday afternoon, Saturday, and most of Sunday are let-downs with onshore winds, fading swell, and short-period slop. By Monday 24 August the swell just about disappears – 1.0ft and glassy early but hopelessly small.
Tuesday 25 August afternoon sees a pulse of 5ft west swell at 10 seconds with a fresh cross-offshore breeze, giving clean conditions. The combined energy jumps to 369, which is moderate. This is the most interesting day of the window in the first week but it's still not a standout.
For the second week, things go a bit wild but not good. From Wednesday 26 August through the 1st of September, we get a series of stronger onshore and cross-onshore winds, often fresh to strong, with messy condos. Swell picks up to 8ft by Tuesday 1 September (795 and 857 energy) but the NW wind is cross-onshore and rough – that’s expert-level size but blown to bits, ugly, and only for the brave. That setup actually looks more interesting for kite surfing than a paddle session.
There’s no true standout – no magical day where everything lines up well. If you’re picking, Friday 21 August morning is the cleanest micro-wave window, and Tuesday 25 August afternoon gives you the best chance at some chest-high, clean lines with that cross-offshore breeze. Other than that, it’s a long stretch with a heap of no-go days. Welcome to late summer at Constantine Bay.
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.
