The Lowdown
Right then, folks. Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
Alright, straight up, I'm looking at a pretty grim picture for Porth Ceriad over the next 16 days. We're staring down the barrel of a long, quiet stretch. The first couple of weeks are basically a write-off, with nothing but tiny, weak dribbles and flat spells dominating the forecast. The water's sitting at 67°, which is a good 7° warmer than you'd expect for this time of year. That's a proper anomaly, feels like we're in a bathtub, but it doesn't help the waves.
There's a gap of nothing worth mentioning from now right through to the end of July. We're not talking about a proper wave until a pulse shows up on Sunday the 26th of July. Even then, it's not great. The morning will see a 4 ft swell from the SW, but with a short, weak period of 6 seconds and a cross-off wind from the NW. The combined energy is only moderate at 109, so it's got a bit of push, but it's messy. By the afternoon, it drops back to 3 ft. The rest of the week is a write-off again, with more onshore slop and nothing but wind.
So, what's the best on offer? Honestly, there's no standout. The only session that might be worth a paddle is on the morning of July 26th. The swell is over 5 ft, so it's a bit much for beginners, but the wind is cross-off, which will keep it cleaner than the rest of the junk. The short period means it'll be a bit fat and crumbly, though. It's not a day for the history books, but if you're desperate, you'll get a few. The rest of the window is a total blank. Porth Ceriad is a fairly consistent spot, so this is a particularly poor run. Forecasts can change, but for now, I'd be doing something else.
Rusty.
