The Lowdown
Right folks, Rusty here. Let's take a look at what's on the cards for the next couple of weeks down at Poldhu Cove.
First thing to say is, it's a bit of a slow burner. The first recommendation doesn't pop up until the morning of Sunday the 7th, and even then, it's a tough call. The setup is a bit of a mixed bag, so we're in for a patient wait.
The first real action that catches my eye is the Monday morning of the 8th of September. We've got a 7ft swell rolling in from the W, with a period of 10 seconds – that's a decent groundswell that'll have some push. The combined energy is a solid 1367 (moderate to strong energy), and the best part? The wind is from the NNW, a clean offshore breeze that'll have the faces looking smooth. It's a morning session, for sure, before the wind swings around in the arvo. This is the standout of the first week.
Now, the best on offer across the whole 16-day window? That's got to be the morning of Tuesday the 16th of September. The numbers are good – a 6ft swell from the W, with a 10-second period, and the combined energy is a healthy 630. But the real story is the wind: a dead calm, glassy morning. Absolutely zero wind. For a fairly exposed spot like Poldhu Cove, that's a gift. The waves will be clean, peaky, and have plenty of shape. It's a bit of a wait, but if you're keen, that's the one to circle on the calendar. It's a promising long-range call, but keep an eye on it.
The week before that, on the 15th of September, the Tuesday morning and afternoon both have a clean cross-off breeze from the NNW and some swell, around 5ft to 6ft, but the scoring is marginal. It's a worthwhile backup option if the glassy day doesn't pan out.
The water temp is about average for this time of year, nothing to write home about. Just your standard wetsuit job.
Poldhu Cove is inconsistent, so you'll be waiting for sets. And when it's good, the crowds can turn up, so expect company if you score that glassy morning.
Alright, that's the long and short of it. A bit of a slog to start, but there's some real promise in the second week. Keep your eyes on that Tuesday the 16th.
Rusty.
