The Lowdown
Right then, let's have a look at what's cookin' for Poldhu Cove.
To be honest, mate, it's a bit of a rough patch we're lookin' at. The forecast is a long, drawn-out affair of poor surf conditions and messy breezes. There's no standout session worth gettin' your wetsuit wet for, so we're talkin' about a 16-day period with nothin' you'd want to paddle out for.
The water is a touch warmer than normal, sittin' around 65°, but that’s small consolation when the waves are so ordinary. The first glimmer of anything even remotely surfable doesn't show up until Sunday the 6th of September. That Tuesday the 25th and Wednesday the 26th are a total write-off with tiny, weak swell. The energy is pitiful—just 148 (weak) on Tuesday, droppin' to 68 and then 50—with a 2 ft to 2 ft West swell and onshore junk winds. On the 27th, the swell picks up a bit, but the onshore wind ruins it. The 29th and 30th are just wild with storm winds. We see a big spike of energy on Saturday the 29th, blastin' 558 (moderate), then a whopping 1060 (strong) on the afternoon, but that's a 10 ft onshore mess with a near-gale cross-onshore. Totally blown out. This carries on for days—big swell but with onshore or cross-onshore winds wreckin' every session from the 1st to the 4th of September. The energy is poundin'—989 (moderate) and 785 (moderate)—but it's all onshore junk.
The first real hint of a clean-up comes Saturday the 5th of September, with a fresh cross-offshore wind, but the swell has dropped to a mellow 4 ft at 11 seconds. That is a solid, long-period groundswell, but with only 397 energy, it's not a big day. Then, on Sunday the 6th of September, we finally get a true window. The morning brings glassy conditions—a slight SSE wind, dead flat, 2 ft West swell with a 9-second period. The energy is only 90 (weak), and the notes say "surfable waves but very ordinary conditions." It's nothin' to shout about—just a tiny, clean ankle-snapper for a patient soul on a log. That's the best of a bad bunch. After that, it goes straight back to messy on the 7th with an 12 ft beast and 25 mph onshore wind, so no dice.
So, bottom line: You're waitin' a long time. The best you'll get is a quiet, glassy little number on the morning of Sunday the 6th of September. For everyone else, the whole period is a bust. The break is inconsistent at the best of times, and this is one of those times.
