Alright, Rusty here. Let’s have a look at what’s on the cards for Fishermans (Rhiw).
Honestly, mate, this is a pretty bleak run. We’ve got a solid 16-day window ahead, but the first week and a half is basically a write-off. There’s a gap from now, starting Monday 6th July, all the way through to the morning of Friday 17th July where you’d be hard-pressed to find a wave worth paddling for. The combined wave energy is stuck in the low double and single digits – 11 to 16 – which is barely a bump. The swell is tiny, usually 0.3ft to 2ft, with short, weak periods. The wind is mostly onshore or strong cross-offshore, and the surf report just keeps saying “poor surf conditions.” It’s a proper flat spell.
From the morning of Friday 17th July, we start to see a flicker of life. The swell bumps up to 2ft from the SW, but with a short 5-second period and energy only at 16, it’s still pretty average. The wind is a fresh cross-offshore, so it’ll be clean, but there’s just no push. This continues through to Monday 20th July afternoon. That Monday afternoon is the first time we get a bit of hope: the swell jumps to 4ft from the SW, with a 5-second period, and the combined energy hits 77. That’s still weak wave energy, and the wind is a moderate cross-offshore. It’s clean and glassy-looking, but that short period means it’ll be a bit crumbly and fat on the reef. It’s the best of the bunch, but not a standout.
Tuesday 21st July morning fades back to 2ft and 42 energy with a stiff cross-offshore wind. The window closes with nothing special.
Look, there’s no true standout here. The only day that might give you a few grovelly rides is Monday 20th July afternoon. The swell is only 4ft and coming from the SW, which matches the optimum direction for the reef at Fishermans. The wind is cross-offshore, so it’ll be clean, but the short period means the waves won’t have any real shape or power. It’s not one for beginners – that size is manageable, but the short period and reef bottom can make it tricky. For the rest of the period, you’re better off finding a different hobby.
Rusty, signing off.
