The Lowdown
Right, let’s have a look at what’s on the table for Fishermans (Rhiw) over the next couple of weeks. I’ll be straight with you – it’s a tough run.
Overall, this stretch is looking flat as a pancake for days on end. We’ve got a real dry spell here. From now through the end of July and well into the first week of August, the wave energy is barely registering, with combined swell energy hanging around 0 to just 9 (weak). It’s a prolonged gap with no real surf to get excited about.
Let’s walk through it. Thursday the 23rd through to Friday the 24th, we’ve got zero swell showing, just tiny 0.3ft waves on the Friday with a 13-second period, but that’s from the west with a cross-off N/NW wind. It’s clean, but there’s no push. Saturday the 25th kicks up a little to 2ft–3ft, but that’s a short-period 4–5 second windswell from the W/WSW, and the wind is a messy cross-onshore, making it choppy and lumpy. Not worth paddling out.
Sunday the 26th through to Wednesday the 31st is a real slog. Swell stays tiny, mostly 0.3ft to 2ft, with periods between 4 and 6 seconds. The wind does go cross-off or light on a few days, giving clean conditions, but there’s simply no wave height to work with. The combined energy is next to nothing – values like 5, 3, 2, and 8 (weak). You’d be bobbing around with no ride.
Thursday the 1st of August brings a bit more wind, but the swell is still just 0.3ft–0.7ft, and it’s cross-onshore or onshore. On Sunday the 2nd of August, we finally see a pulse: 4ft swell from the west with a 5-second period, and the combined energy jumps to 111 (moderate). But look at the wind – it’s a moderate cross-onshore and choppy, so that lumpy, messy wave won’t be clean. It’s more interesting for kite surfing than paddle surfing, to be honest.
Monday the 3rd of August gives us a clean morning with a light offshore NE wind at 2ft, but it’s a short 6-second period and only 17 energy (weak). Not enough to call it a go. The rest of the first week of August fades right back to nothing.
The only flicker of hope, and I mean the faintest one, is around Sunday the 2nd of August morning, when that 4ft west swell shows up. It’s the biggest of the whole run, but with the wind cross-onshore and choppy conditions, it’s not a standout. It’s just the best of a bad lot.
Given the near-total lack of consistent swell and the poor quality forecast, this is a blank run for the area. It tends not to stay poor for long, and forecasts can change, but right now there’s nothing to recommend.
Take a break, lads. The ocean’s having a nap.
