The Lowdown
Alright, Rusty here, and I’ve been staring at the charts for Poldhu Cove. Let’s break it down.
Right off the bat, the water’s sitting at about 64°, which is a touch warmer than usual for this time of year – nothing freaky, just a little blanket on the water. But that’s about the only easy-going thing, because for the first full week, we’re pretty much locked out of anything decent. The wind is howling from the west and southwest, cross-onshore and choppy, messing up the 5ft to 8ft swells we do get. It’s a choppy, lumpy mess out there for most of the first week.
Now, there is a real standout. Saturday the 5th of September, morning session. That’s the one to circle. We’ve got a 6ft groundswell rolling in from the west with a very long 12-second period. The energy is solid – moderate to strong in the 800-range (804). But the kicker? The wind goes glassy. Dead calm. That west swell, with those long waits between sets, will be peeling nice and clean. It’s an inconsistent break here, so you’ll have to be patient, but when those sets come through, it’ll be worth the wait. Expect a few other locals out, but it won’t be a zoo.
After that, it’s back to messy, windy conditions for most of the week, but keep your eye on Monday the 14th. The morning is looking clean again with a 5ft west swell and a 10-second period. We get a nice cross-offshore breeze from the north-northeast, which should scrub up the faces proper. The energy is moderate (428). The Tuesday morning after that, the 15th, is also looking good – another glassy morning with a 4ft west swell and clean faces.
Honestly, the real winner is that Saturday morning. It’s not huge, but when you get glassy conditions and a long-period groundswell at an inconsistent spot like Poldhu Cove, you take it. The Monday the 14th is a solid backup plan. The rest of the fortnight is mostly blown out or too weak to get excited about.
Rusty, signing off.
