The Lowdown
Alright, Rusty here again. Let’s call it like it is – we’ve got a proper flat spell coming up. The only break in the game is Aberystwyth harbour trap, and the outlook is a tough one. The water’s running much warmer than usual for the season, at 20°, but that’s where the good news ends.
Over the full 16 days, from July 14th to the 29th, there’s nothing worth paddling out for. Every single entry is flagged as poor surf conditions with a zero score. Wave heights are a measly 0.3ft to 3ft at best, with weak combined swell energy (6 to 66) and short periods under 8 seconds. The wind is mostly cross-off or cross-on, and the few glassy moments happen when there’s no swell at all.
You get a tiny pulse on the 27th and 28th of July, with a 3ft swell from the WSW and a 6-second period, pushing the combined energy up to 66. The wind is cross-off or glassy, so it’d be clean, but with that little height and a short period, it’s just not going to wrap in properly. It’s a frustrating run.
For this area, a stretch like this is more normal than unusual. Don’t hold your breath. Forecasts can always shift, but for now, the racks are staying dry.
Rusty.
