The Lowdown
Alright folks, Rusty here with a look at what’s ahead for us. To be straight with you, the next couple of weeks are a proper mixed bag, with a fair bit of wind and chop to sift through. We’ve got some clean windows, but you’ve gotta pick your moments. The first real opportunity doesn't show up until the 15th.
Let’s kick it off with the standout. The best of the best looks like the 19th of September down at Poldhu Cove. Saturday morning is looking promising with a clean 5 ft swell from the west, a period of 11 seconds, and a cross-offshore breeze from the east (12 mph) that should keep things tidy. The combined swell energy is solid at 498 (moderate). Then the afternoon cleans up even more. Glassy conditions, a 4 ft west swell with 10-second period, and a light cross-offshore breeze from the ESE (9 mph) – the report says "clean" and "expect good surf conditions." That's the one to mark in your calendar. It’s not huge, but the quality is set to be excellent. The water temp is running about average for the time of year, so no surprises there.
Before that, the 13th of September – Sunday – has a moment. The morning shows a 5 ft west swell with a nice 10-second period and it’s near glassy (3 mph cross-shore). The energy is respectable at 433 (moderate), but the call is only "marginal," so keep your expectations in check.
Now for the bigger stuff. The 16th of September sees a pulse jump to 10 ft from the west with a 10-second period, and the energy rockets up to 1737 (very strong). But it comes with an onshore wind, making it one for the experts only, and even then, it’ll be a mess. A couple of other days, like the 23rd of September, serve up a 7 ft west swell with 11-second period and a massive 1107 energy (strong), but again, you’re battling a fresh cross-offshore breeze that’s too strong for good shape.
The rest of the window is mostly filled with poor surf conditions: onshore winds, chop, and smaller swells. There are a few days with clean wind but tiny waves. The 22nd of September, for instance, has perfect offshore wind but only 1 ft to 2 ft of swell.
Since Poldhu Cove can be inconsistent, don't be disheartened if it takes a while to fire. But when it’s on, like that Saturday the 19th, it’s a beauty. Do be aware that crowds are possible on the better days.
Stay patient and keep an eye on that 19th.
Rusty.
