The Lowdown
Alright, mate, Rusty here. Let's be straight with you – it's looking pretty bleak on the surf front for the next couple of weeks. I’ve scanned the forecast for Aberystwyth harbour trap, and honestly, there isn't a single moment where I'd tell you to grab your board with a grin. It's a proper flat spell, and we're just going to have to sit tight.
The water temp is sitting at 65°F, which is a whopping 5°F warmer than usual for this time of year. That's a seriously warm ocean for September, so at least if you do get out for a paddle, you won't need a thick suit.
Right, we're starting now, and there's nothing to start with. The coming days are a write-off. Friday the 4th sees some lumpy, cross-onshore slop with swell energy only around 106, and it just gets worse. We're looking at a gap of several days here where you'd be better off doing anything else.
We get a tiny teaser on Monday the 7th. The morning shows a pulse of long-period swell at 14 seconds with moderate energy of 253, but it's completely ruined by a strong cross-onshore wind. It's a classic case of a bit of raw power with nowhere to go in clean conditions. The swell direction is from the west, but it's just not coming together.
The following week is more of the same. There's a bit more size around Tuesday the 15th – we're talking 6ft of westerly swell – but it's short-period, wind-blown stuff with energy of 340. It will be lumpy and messy, offering no real shape. For a reef break like this, you'd want it clean and lined up, and it's just not going to happen. And honestly, anything over 5ft like that with this wind is going to be a challenge for anyone, not just the beginners.
There is one tiny spark of hope on Friday the 18th. The morning shows 5ft of WNW swell with a clean, offshore east wind. The energy is weak, only 139, but for a moment, it might just have a bit of shape. It’s more of a “maybe” than a “go”, and it’s a long way off, so don't hold your breath.
Honestly, the setup looks more interesting for the kite surfers than for us paddle surfers out there. All that wind and chop with no clean swell is their playground, not ours. It's a frustrating outlook, but a blank run like this is more normal for the area than we'd like to admit. Forecasts can change, so we'll keep an eye on it, but for now, my advice is to find a nice pub and enjoy the warm weather.
Rusty, out.
