Alright folks, Rusty here. Let’s have a look at what’s on the cards for Fishermans (Rhiw).
To be straight with ya, it’s a pretty bleak run for the next sixteen days. There’s no real surf to get excited about at all. We’re looking at a big fat gap of flat, clean conditions and tiny, unrideable dribble. Don’t bother checking the beach for any real waves until we get deep into the second week, and even then, it’s not going to be any kind of proper session. The signals are weak across the whole period; the swell is basically absent, with the combined energy topping out at a meagre `66` (moderate) for a brief moment, but with the wind blowing hard and wrong. After that, the energy drops right back to `2` or `0` for days on end.
The first real chance of a ripple comes around Friday morning, July 3rd, but it’s a piddly `1 ft` from the SW with a short period of `6` seconds and a howling onshore wind. It’s a total write-off. This theme of small, windy, and poor continues straight through until the middle of the month. The water temp is about average for this time of year, not that you’d be in a hurry to get out there in these conditions.
Around Sunday, July 12th, we get a very brief window of clean, glassy conditions on the morning of the 13th, but that’s because there is literally no swell—a flat zero. On Monday afternoon, July 13th, we see something from deep in the ocean, a `14` second period groundswell from the SW, but it’s only `0.3 ft`. The combined energy is still poor at `18`, so it’s more of a visual curiosity than a wave you can surf. The wind on that afternoon is a gentle cross-shore, causing a little chop, so even that tiny pulse is messy.
From there on, it’s more of the same: tiny swell windows with onshore winds, or strong cross-offshore winds on flat days. The last day in the outlook, Saturday, July 18th, is a total blowout with strong cross-onshore winds and lumpy water. There isn’t a single standout session in the entire 16-day run. If you’re desperate, keep an eye on the 13th for that long-period bump, but don’t hold your breath. For now, it’s a waiting game.
Rusty.
