Alright folks, Rusty here. Let's take a look at what's on offer at Fishermans (Rhiw) over the next couple weeks.
Honestly, I gotta level with you—this stretch of the forecast is looking pretty bleak for us. The swell window is just not cooperating, and we've got a long stretch of flatness and poor conditions to deal with. We kick off on Saturday, July 4th, with a weak 4ft swell from the SW, but that's about 5 seconds of period and a stiff 19 mph cross-onshore wind. The water's a touch warmer than usual at 62°F with a 4°F anomaly, which is notable, but the combined energy is just a paltry (51). That's not surfable, it's just messy.
We then hit a massive dead patch. From the 5th of July all the way through to the 18th of July, there's simply no worthwhile swell. We're talking over two weeks of zero to tiny, short-period bumps (0.3ft or less), and the best we get is some glassy mornings like on Wednesday, July 8th, or Friday, July 10th, but with no waves to speak of. You could paddle around in the calm water, but you aren't catching anything.
Finally, on the 19th of July, a pulse of 2ft swell shows up from the ESE with a short 4-second period and light cross-shore winds. The combined energy is weak (14). This is a little windswell bump, but with that period, it's gonna be choppy and weak. It's not a standout in any sense—just the only thing on the board. Honestly, for this area, a blank run like this is more normal than not. The setup is more interesting for kite surfing than paddle surfing right now. I wouldn't hold my breath.
Rusty.
