The Lowdown
Alright, folks, let's take a look at what's on the table. I'm gonna be straight with you – it's a lean run for Fishermans (Rhiw). This is a reef break, pretty exposed to a SW swell, but the whole 16-day window is a struggle. We're looking at a long stretch of poor surf, so if you're itching for a paddle, you might want to find something else to do.
The first week is a write-off. From Thursday the 6th right through to at least the middle of the month, the swell is tiny and the wind is all over the shop. We're talking waves mostly under 3 ft, with a combined swell energy that barely gets into double digits – the biggest we see early on is a measly 65 (weak energy). Thursday morning has a little 4 ft WNW windswell, but it's a 5-second period and a 16 mph cross-wind, so it's just a mess. The water temp is sitting at 63 °F, which is a touch warmer than normal for this time of year.
The second half of the month doesn't get much better. We get a few cleaner moments around the 16th and 17th with some cross-offshore breezes, but the swell is still tiny. Sunday the 16th afternoon has a 4 ft SW swell with a clean 12 mph NNW cross-offshore wind – that's about as good as it gets, but it's a short-period 5-second wave, so the energy is weak (68). It's not going to be a proper ride. By the 19th, a long-period 16-second groundswell shows up, but it's only 0.3 ft. That's practically flat, even if the wind goes glassy. The 20th and 21st just have more onshore gales and tiny waves.
There is simply no standout session in this outlook. Nothing is worth highlighting. It's one of those periods where the ocean just isn't cooperating. Don't hold your breath for a change; forecasts can shift, but as it stands, this is a dry spell.
