The Lowdown
Rusty here again, same story, different numbers. We’re in for a quiet couple of weeks at Aberystwyth harbour trap, a little reef spot that can fire, but it’s gonna take a while.
The first real hope hits on the 24th of September. Thursday morning brings a 5.2ft swell from the WSW at 6 seconds. The energy is solid at 176, but the cross-shore breeze will have it messy.
The one to circle on your calendar is the morning of the 25th of September. That’s the winner. We’ve got a clean 5.6ft of WSW swell with a 7-second period, and the wind is offshore from the ESE at 6 mph. It’s going to be glassy, clean, and the energy is strong at 255. This is the window for an intermediate surfer to get some proper, groomed waves. Just a heads-up, this place can get busy, so get there early.
The afternoon of the 25th keeps the good vibes with glassy conditions and a 4.6ft swell from the WSW, still worth a paddle.
But before that, mate, it’s a brutal stretch. From now until the 23rd of September, you’re looking at a flat, windy mess. We’re talking tiny 0.3ft bumps with strong, messy onshore winds. It’s all just drift and chop. Don’t bother until that 25th of September rolls around.
