The Lowdown

G'day, I'm Rusty. Let's look at what's on offer down at Fishermans (Rhiw) over the next couple of weeks.

Honestly, the first week and a bit is a write-off. We're looking at poor surf conditions for days on end. The swell is small, short-period, and the wind is mostly cross-on or onshore, mushing everything up. The first time we see a glimmer of hope is on Friday the 11th of September. That's when a real pulse of energy arrives. The combined swell energy jumps to a moderate 502 in the morning, climbing to a strong 372 in the afternoon. We're talking about 8 ft of swell at first, coming from the WSW with a short 7-second period, so it won't be the cleanest, but the wind finally swings offshore, and that makes all the difference.

The standout here is undoubtedly Sunday the 13th of September. The afternoon session is the best bet of the whole outlook. You've got a solid 7 ft swell from the WSW, and the combined energy is a strong 329. But the real beauty is the wind – it's a light, offshore breeze from the NW, going clean across the reef. That's going to make Fishermans (Rhiw) look absolutely perfect, with clean faces and good shape. For this break, with its optimum direction being SW, this is a real aligned pulse. It's a quiet little spot, so crowds are only a sometimes thing, which is a bonus.

After that, there are a few more blown-out days, but we do have one more interesting one further out. On Wednesday the 16th of September, the morning shows a massive 8 ft swell from the SSW with a combined energy of 758 – that's very strong. But the wind is cross-off from the NW, so while it'll be clean, that size and short period (7 seconds) will be a heavy, draining wave for experts only. The afternoon picks up a bit more period (9 seconds) but gets messy with a strong cross-shore.

So, to sum it up: with water temps about a degree and a half warmer than average for the time of year, the first proper surf doesn't really get going until the second week. The true standout is Sunday the 13th of September, afternoon session at Fishermans – get that in the diary as a promising one, but remember it's a long-range call.

Rusty.
