Alright folks, Rusty here. Let's have a look at what's on the table for the next couple of weeks, but I gotta be straight with you—it's a lean stretch ahead.
Right now, there's absolutely no surf worth paddling out for at Fishermans (Rhiw). The whole 16-day forecast is filled with flat spells and tiny, weak, choppy waves. We're talking a lot of zeros on the energy scale, and the swell that does show is tiny and short-period—rubbish. The water's sitting at 62°F and it's a touch warmer than usual for this time of year, but that's about the only highlight.
We kick off Saturday, July 4th, but don't get excited. It's a total write-off: 3 ft of weak, cross-onshore slop at 6 seconds from the WSW, with the combined energy barely registering at 56. The wind is a fresh 19 mph from the SW, making it lumpy and horrible. Saturday afternoon is even worse with 4 ft but an even shorter 5-second period and the same mess. Sunday the 5th is more of the same—tiny 2 ft and 2 ft waves, still cross-onshore. Monday the 6th drops to a measly 1 ft. The combined energy plummets to just 8.
Tuesday the 7th morning goes glassy, but there's only 1 ft of 4-second junk with a combined energy of 7. Not worth getting wet for. From Wednesday the 8th right through to Sunday, July 19th, we see a long gap where there's essentially nothing. Most days show zero swell or just a tiny 0.3 ft Western swell, with combined energy values of 0, 1, or 2—barely a ripple. The wind does go offshore or clean a few times, and glassy conditions pop up on the 8th afternoon and 13th morning, but there's no wave to ride. A very long-period groundswell from the West on the 13th afternoon gives us a period of 19 seconds, but the height is only 0.3 ft with a combined energy of 12. That 19-second period would be unreal for a point or reef, but there's zero power behind it. It's a tease.
Honestly, this is a blank run for the area. There isn't a single standout window in the whole 16 days. If you're itching to get in the water, maybe check the kite gear because with these conditions, even the surfless breezes look more promising for that. Otherwise, hold tight—forecasts can change, but right now, the coffee shop is the place to be.
Rusty.
