The Lowdown

Alright, Rusty here. Let’s have a look at what’s coming down the line over the next couple of weeks.

To be straight with you, this is a tough stretch for Fishermans (Rhiw). The first proper surf on offer doesn’t kick in until the 28th of September, which is a full ten days away. We’ve got a long stretch of slim to none before that, with only minor, messy, or flat days in between. If you’re desperate for a paddle, you’ll be waiting a while.

The best of the whole run looks like it’ll be Monday the 28th of September. That morning, we’ve got a pulse of swell pushing in around 10ft from the WSW, with a combined energy reading of 1093 – that’s some serious power. It’s a touch cross and a bit messy that morning, though. But by the afternoon, the wind swings NE, turning offshore, and the swell drops back a bit to 8ft, still from the WSW and with energy down slightly to 1037. That afternoon window is your standout: clean conditions, solid but not stupid-big size. That’s big enough to be expert territory at over 8ft, so know your limits. The water temp is sitting at 63°F with a positive anomaly of 3°F, so noticeably warmer than average for this time of year – a nice bonus.

The following morning, Tuesday the 29th, still has some decent leftovers around 6ft from the W, but the wind is more cross-off and the energy has dropped a lot, down to 238. It’s surfable, but not a patch on the day before. Afternoon holds another glassy 6ft spell, but again the punch is gone. After that, it fades right back into small, onshore mush.

Crowds at Fishermans (Rhiw) can show up sometimes, so on that standout Monday afternoon, you might have company. But with good surf so scarce, it’ll be worth the squeeze.

Alright, that’s the tale for this stretch. Better luck next time, maybe.
