The Lowdown
Alright, Rusty here. Let's have a look at what we've got on the cards for Poldhu Cove over the next couple of weeks.
Straight up, it's a grim start. The first four days are a write-off. Strong onshore winds, messy conditions, and the wave quality is just not there. You wouldn't want to be out there. Give it a miss.
Things start to look a little more promising towards the end of the first week. Saturday the 5th of September has a small window in the morning. We're looking at a 4ft swell from the west with a 10-second period, and the wind is light and cross-offshore. The combined energy is moderate (297), and the forecast says clean. It's not going to be huge, but it'll be the first sign of life. The water temperature is about average for the time of year, so nothing unusual there.
Sunday the 6th drops right off, with tiny swell. Not worth the paddle.
Then, hold onto your board. The standout is shaping up for Friday the 11th of September. The morning session has the makings of something special. We've got a solid 7ft swell pushing in from the west, and the wind is forecast to be glassy – dead calm. That's a huge positive. The combined wave energy is strong at 773. The waves will be clean and well-shaped. This is the one to circle on your calendar. It's the best on offer by a long shot.
The afternoon of that same Friday is bigger, hitting 8ft from the west, but the wind turns cross-shore and the conditions get a bit messier. That size is pushing into expert-only territory anyway.
The following week, the long-range outlook is more uncertain. There's a chance of some clean, offshore winds around Tuesday the 15th of September, with a 4ft west-southwest swell and a long 12-second period. The energy is moderate (382), and with a gentle offshore breeze, it could be fun. But it's a week and a half out, so treat that as a hopeful possibility rather than a guarantee.
All in all, it's a slow start, but that Friday the 11th has the potential to be a cracker. Poldhu Cove is an inconsistent spot, so when the stars align like that, you gotta be ready.
Rusty.
