The Lowdown
Alright, this is Rusty, and I’m looking at the next couple of weeks for Aberystwyth harbour trap. I gotta be straight with you – it’s grim. The whole 16-day window is a write-off for any decent paddle. There’s not a single session that’s worth getting wet for. The energy is just pathetic, barely cracking double digits (1) for most of it, and the biggest combined energy we see all period is a weak 50 on the 20th of August, which is still tiny. It’s one of those blank runs that happens here, and it’s a stubborn one.
The water is weirdly warm for this time of year, clocking in at 67°, which is a full 6° above the norm – that’s very unusual. But that’s the only interesting thing.
Let’s run through the pain. Saturday 8th through the whole first week? Nothing but poor surf. We’re talking knee-high dribble at best, with onshore or cross-onshore breezes messing up what little bump there is. The 12th of August morning has a moment of glassy conditions with a 0.7ft leftover from a WSW swell, period 10 seconds, but even that combined energy is only 10 – it’s just a lake with a ripple. Not worth paddling for.
The 15th of August afternoon sees a bit of a spike with a 3ft NNW windswell, but the period is a shocking 4 seconds and the wind is a moderate 12 mph cross-onshore. It’s going to be a choppy, weak mess. The 20th of August has the biggest swell of the whole run, 3ft from the W, period 5 seconds, with a 9 mph onshore wind. The combined energy is 50, which is still weak. It’ll be a messy, blown-out shorebreak.
The last few days of the run, 22nd and 23rd of August, see a 16-second and 15-second period swell creep in, but it’s barely 0.3ft. That’s a long-period groundswell with zero height. It’ll just be a surge, not a wave.
Honestly, save your wax. The entire 16 days are a bust. The setup here is more interesting for a kite surfer than a paddle surfer on those bigger, windier afternoons, especially the 15th and 20th. But for a surfboard? Nothing. Stick to the skatepark.
Rusty.
