The Lowdown
Alright, let’s get this straight. Looking at the next sixteen days, the honest truth is that Fishermans (Rhiw) is going to be mostly a flat, blown-out mess. I’ve got no good options for you in this whole window. It’s a blank run, plain and simple, and for this stretch of coast, that’s not all that unusual.
The pattern is pretty bleak. We start off with tiny, weak surf. August 1st has a mere 1ft of weak southwest swell with a short 5-second period, and the wind is all over the place, so it’s not doing us any favors. The next few days aren't any better. Through the 2nd to the 4th, we’re looking at ankle-biters under 2ft. There’s a moment on the morning of the 4th where it goes glassy, but with wave energy down at 21, it’s dead calm and flat. Not worth paddling out for.
There’s a slight pulse of energy around the 5th, with the swell bumping up to 3ft. The period is a weak 6 seconds though, and it’s cross-onshore, making it a crumbly, messy closeout. The 6th cleans up a bit with a cross-offshore breeze, but the swell drops back down to 2ft. It’s surfable for a beginner at best, but it’s not something I’d get excited about. The energy is still weak at 47.
We get a sniff of longer period swell on the 7th, with a 12-second period, but it’s only 0.3ft. That’s just a pulse of energy with no size behind it.
The middle of the month sees a slight increase in size but zero quality. On the 11th and 12th, we get up to 3ft and 4ft of swell, but it’s all short-period windswell from the southwest with onshore winds. It’s going to be lumpy and jumbled. Doesn’t matter if it’s 4ft if it’s breaking like a washing machine.
The last few days of the forecast are just a write-off. From the 13th onward, we have strong to gale-force winds howling onshore. The 13th sees 28 mph winds with just 1ft of swell. That’s a complete blowout. The 16th is even worse with 31 mph near-gale winds. It's going to be a total ocean.
Now, if you’re a beginner, there’s nothing here for you either. The only time it gets over 5ft, which is getting too big for you, is non-existent. The bigger swells we see are still under that mark but are made horrible by the wind.
Honestly, the only thing this forecast is good for is looking at from the shore with a coffee. With that much onshore wind and a beach setup, the conditions look far more interesting for a kite surfer than anyone on a paddleboard. Save your energy. The ocean will come back around, it always does.
