The Lowdown

Right then, let’s have a look at what’s on the table for the next couple of weeks. To be straight with you, I’ve got to be honest: this is a pretty bleak stretch for Poldhu Cove. There’s no real standout day here, not a single one I’d call a classic. The whole 16-day window is basically a write-off for decent waves. We’ve got a lot of days where the swell is tiny, the wind is all over the place, or the conditions are just plain messy. There’s a long gap from now until the end of the month where you’d be wasting your time.

Let’s run through it. Starting off, Friday the 21st of August, we’ve got a bit of swell around 4ft from the west, but the wind is a moderate cross-off from the north at 15 mph. The combined energy is weak at 247, and the report says it’s poor. That sets the tone. Saturday and Sunday don’t get any better, with swell dropping right off to 2ft or less. Then we hit a real doldrum period from Monday the 24th right through to the end of the month. The swell stays under 3ft, and when it does push up a bit mid-week, like Wednesday the 26th with 5ft from the south, it’s accompanied by fresh onshore winds or even storm risks, making it a total mess. The combined energy gets up to 437, but with an onshore wind and a short period of 7 seconds, it’s just a lumpy, choppy disaster. That pattern basically holds – some moderate energy but always with the wrong wind direction. Friday the 28th sees 6ft from the WSW but with a strong cross-shore wind at 28 mph. Not for paddling.

There’s a brief flicker of hope on Thursday the 3rd of September. The swell is tiny, just 1ft from the SSW, but the period is a long 15 seconds. The wind goes glassy in the morning. That’s about the cleanest it gets, but with that combined energy at just 82, it’s barely a ripple. A long-period, tiny swell like that might show a little shape on the right bank, but it’s a gamble. The next day, Friday the 4th, is similar – clean but tiny.

Then, right at the very end of the window, on Saturday the 5th of September, we get the closest thing to a session. The swell is 5ft from the southwest, with a period of just 5 seconds – so a short, weak windswell. But the wind is actually offshore from the ENE at 12 mph, and the combined energy is a moderate 149. It’ll be clean and a bit more pushy than the rest, but that short period means it’s not going to have any power or shape. A real waiting game.

So, what’s the best on offer? Honestly, there isn’t one. If you had to pick something, that Saturday the 5th is the only day with offshore wind and some size, but it’s still a very ordinary, weak windswell. For the rest, you’re looking at flat spells or blown-out junk.

Information about the Poldhu Cove Surf forecast

The above surf forecast table for Poldhu Cove provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Poldhu Cove can be found by selecting the local surf guide option on the grey menu. Our Poldhu Cove 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 (Poldhu Cove) 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 Poldhu Cove 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.
