The Lowdown
Alright, let’s talk about Poldhu Cove (Poldhu-Cove) in feet and miles. The water’s a touch warmer than usual, sitting around 64°.
Honestly, the first week and a half is rough. Nothing worth paddling for until Wednesday the 16th of September. Wednesday morning sees head-high-plus swell, about 7ft from the west, with a light offshore breeze from the NNW. The swell energy is moderate to strong (1104), but the whole thing is only rated marginal. That afternoon, the wind turns bad.
After that, it’s a mess – strong winds, lumpy sea, and poor conditions all around. There’s a pulse of 6ft west swell on Sunday the 20th with a long 14-second period and strong energy (1186), but the cross-shore wind keeps it from being clean. Still too dicey.
The only real standout, and the one day you should circle in red, is Monday the 21st of September. Monday morning is a beauty. The wind goes dead flat – glassy – and you’ve got a nice 4ft west swell with a 13-second period. Energy is moderate (594). This is the only window in the whole 16-day forecast that’s expected to be good. Poldhu Cove can be a bit inconsistent, and it’s fairly exposed, liking a southwest swell more than this west one, but with zero wind, you’ll get some clean, lined-up waves. It’s a fun size for most surfers. After that morning, the swell fades.
The end of the month is tiny – 1ft or less. Clean, but flat.
So, to sum it up: nine days of mostly junk, one glassy morning on Monday the 21st, then a slow fade to nothing.
Rusty.

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.
