The Lowdown

Alright, Rusty here. Let's have a look at what's on offer for Fishermans (Rhiw) .

Straight up, this is one of those outlooks where you're going to want to keep your longboard on the rack for a good while. There's a massive gap of poor conditions stretching from now right through the first week. We're talking about a solid 10-day stretch where it's just not happening. The swell is tiny and gutless, the wind is all over the shop, mostly onshore or cross-onshore, and the water is a touch warmer than normal for this time of year at 64° in the surf zone, which is nice, but it doesn't make up for the lack of waves.

From Thursday August 27th, we start off with knee-high dribble. A 0.3 ft swell from the southwest with a 12-second period sounds long on paper, but the energy is a pathetic (11) and it's barely making it in. Friday the 28th is a little better, with the swell bumping up to 2 ft but the period drops right off to 6 seconds, making for weak, fat waves. The winds are a mess through the weekend and into the start of September. We get a bit of a pulse on Monday the 31st of August with a 4 ft swell from the WSW, and the combined energy jumps up to a moderate (459), but it's still a cross-shore mess with a cross-chop. It's not worth paddling out for.

Then we hit Tuesday the 1st of September and the whole thing just drops away again, back to nothing. There's a brief moment of hope on Saturday the 5th of September when a 7 ft swell from the WSW shows up with a solid (428) energy score, and it gets a score of 1 out of 10, which is the best we see. But the wind is a light cross-onshore, creating small wind ripples, and the Sunday morning after that looks a bit cleaner. However, the swell drops fast. That 7 ft wave is really the only standout in the whole 16 days, and even then, it's a marginal call. For an exposed reef spot like this, you need the wind to be right, and it's just not for most of the period.

Honestly, there is no day I’d get excited about. The best option, if you were desperate, would be the morning of Saturday the 5th of September. It's the biggest swell of the run with that moderate to strong wave energy (428), coming from the WSW. Remember, this is an exposed reef, so a longer period swell like this from the SW is what you want, but the period is only 7 seconds, so it won't have that proper groundswell grunt. The wind is a light cross-onshore, which is better than a full-on howler but not ideal. Given the crowds are listed as "sometimes," you might have a bit of company if the forecast holds. But this is a long way out, so take it with a grain of salt. For the rest, it's a washout. Keep an eye on the forecasts, because things can change.

Rusty.
