The Lowdown
Right then, let’s have a look at what’s coming up for Poldhu Cove over the next couple of weeks.
Honestly, it’s a pretty grim start. We’ve got a solid run of poor conditions stretching right through the first week and beyond, with hardly anything worth paddling out for. The wind is mostly cross or cross-onshore and often fresh, with lumpy, choppy surf. The water is sitting at 64° for now, a touch warmer than normal for the time of year, but that’s about the only nice thing to say.
The only real glimmer in this whole 16-day window lands on Monday the 21st of September. Monday morning, the wind goes glassy – dead calm, just a slight air moving – and the swell is a clean 4ft from the west with a long 13-second period. The combined energy is moderate at 501. That’s the standout. It’s not big, but with glassy conditions and that long-period groundswell, it’ll be clean and lined up. Just remember, this spot is inconsistent and fairly exposed to the south-west, and with the optimum swell coming from the south-west, it’s a promising but distant call. Crowds are possible there sometimes, so you might not have it all to yourself.
Before that, Wednesday the 16th morning shows a bigger 7ft west swell with a very long 11-second period and clean conditions, but the energy is strong (1086). That’s expert territory at that size, especially with a cross-offshore wind. It’s only a 1 out of 10 on the forecast, though, so it’s marginal at best. Tuesday the 22nd and Wednesday the 23rd have some clean cross-off winds and 4ft to 6ft swell, but the periods are short (6 to 7 seconds) and the energy is weak to moderate, so you’re looking at weak, fat waves.
After the 21st, it drops right off again. By the 25th of September, we’re down to 0.7ft swell from the west-south-west with a 16-second period – barely a ripple, energy at just 48. And then it’s tiny, clean but tiny, all the way to the end of the outlook on the 28th.
So, there’s a long gap of poor surf, one promising Monday morning, and then nothing again. For the area, this kind of blank run is fairly normal, but forecasts can change.

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.
