The Lowdown
Alright folks, Rusty here. I’ve had a good look at what’s coming up for us at Fishermans (Rhiw), and honestly, it’s one of those stretches where the ocean just isn’t playing ball. This is a reef break that’s fairly exposed to the SW, perfect for when a decent south-west groundswell lines up, but we’re looking at almost two weeks of real struggle.
There’s not a single standout session in the whole 16-day window. The first recommendation on the cards isn’t until Saturday the 25th of July, and it's a bit of a non-starter right from the off. We’re looking at a weak SW swell of just 3 ft, with a short period of 4 seconds. The combined wave energy is only 30 – that’s barely a ripple. To make matters worse, a cross-on shore wind from the WSW at 12 mph is going to have it choppy and messy. Even the water, sitting at 63°, is a touch warmer than normal for the time of year.
From there, it’s a long, bleak run. We skip the rest of July and into August with nothing but “poor surf conditions” flagged. Every day is a write-off. There's a bit of a tease on Thursday the 30th of July morning, where we get clean conditions with a light cross-offshore breeze from the NW, but the swell is a pathetic 2 ft. Then again on Friday the 31st of July morning, you’d get dead glassy conditions with zero wind, but still only 2 ft of weak SW swell (22 energy). It’s clean but completely flat – not worth paddling out for.
The whole first week of August is the same story. The swell tries to bump up a little on Saturday the 1st of August with a 4 ft SW swell (84 energy), but a cross-on wind from the south at 9 mph ruins any chance of shape. We get a brief window of cleaner conditions on Wednesday the 5th of August morning with a light cross-offshore NNW breeze, but the swell drops right back to 1 ft. It’s just not happening.
The period from the 5th of August onward really drops off a cliff. Swell heights barely hit 0.3 ft, and the energy values are in single digits. Even the few clean or glassy moments don't matter, because there's nothing to ride.
The only session that even looks surfable is Sunday the 9th of August morning. Swell bumps up to 4 ft from the WSW (94 energy), and while the period is short at 5 seconds, it’s the biggest we’ve seen. But again, it’s a fresh cross-shore wind from the WNW at 18 mph, which will make it lumpy and cross-chop. That setup might actually be more interesting for a kite surfer than a paddle surfer.
So, the bottom line: the forecast is a blank run. For a break that is fairly consistent, it’s a weird quiet spell, but it happens. Forecasts can change, but right now, save your energy.
Rusty.
