The Lowdown
Alright, let’s talk in feet and miles. Rusty here, with the lowdown for Poldhu Cove.
Honestly, this forecast is a bit of a bummer for the next couple of weeks. We’re looking at a solid 9-day dry spell from the start through to the 20th of September. The wind just won’t play ball—mostly onshore or cross-onshore, and pretty breezy, turning what swell there is into a lumpy, choppy mess. Frustrating to watch, that’s for sure.
The one day that stands out, and it’s the real highlight, is Monday the 21st of September. The swell drops right off, but the conditions become bloody lovely. That morning you’ve got a clean 3ft from the West with a proper 13-second period—that’s long-period groundswell with some push. Wave energy is moderate at 353, and a 12 mph offshore breeze from the Northeast will have the face of those waves glassy. It’s an inconsistent spot, so you’ll be reading the ocean between sets, but the quality will be worth the wait. Expect good surf conditions. The afternoon gets even cleaner: a tiny 3ft wave, but with only a 3 mph offshore from the NE and energy at 275, it’ll be almost dead glass. Small, but as clean as you could hope for. That Monday is the only true window here. Water temp is about average for this time of year, so your usual spring suit will be fine.
After that, from Tuesday the 22nd onward it’s mostly small stuff—waves under 2ft and very weak, with the wind switching about. A couple of clean afternoons on the 24th, but with swell barely reaching 2-2ft, there’s just not enough to ride. The last few days get windy and lumpy again, finishing with a bit of a swell jump on the 27th but with strong onshore wind ruining it.
Rusty.
