The Lowdown

Right, pull up a rock and listen. It’s Rusty here, and I’ve got to be straight with you – the next two weeks are a bit of a lean stretch for Fishermans (Rhiw). We've got a long, dry spell ahead with barely a ripple, but there are a few whispers of something at the very end worth keeping an eye on.

Let’s start with the grim bit. From Wednesday the 29th of July right through to Thursday the 6th of August, you’re looking at a blank run. Even if you’re the most optimistic surf-starved soul, there’s nothing doing. The swell is tiny – 1ft to maybe 2ft – with a rotten, short period (4 to 5 seconds) and poor energy readings (5 to 18). Dead low energy. Most of the time we’ve got onshore winds out of the SSW, so it’s messy. We do get a window of clean, cross-off weather on the 1st and 2nd of August, but the swell’s so weak and small it's not even worth getting the board wet. The water temp is about average for the time of year at 17°, nothing special.

Then we roll into Friday the 7th of August, and things finally start to look a little more interesting. The combined swell energy jumps right up to 600 (moderate to strong wave energy), and we’re looking at a solid 8ft swell from the SW, with an 8 second period. That’s a proper size – only for the experts, mind you. If you’re a beginner, give this one a miss, as that’s pushing 8ft. The wind on Friday morning is cross-shore from the WNW at 9 mph, which is clean enough, but it’s a bit bumpy with a cross-chop. The tide and conditions look questionable, so it’s more of a “look at it from the cliff” kind of day than a paddling one. Still, that’s the standout for the whole 16 days in terms of pure size.

Following that, Saturday the 8th and Sunday the 9th of August offer some small relief. Swell drops to 4ft to 4ft (WSW/SW, 8 second period) with combined energy around 133 to 162. The winds are light and cross-off on Saturday afternoon and Sunday morning, giving you clean waves. It’s not epic, but it’s “surfable but ordinary” – you could get a few foam climbs if you’re keen.

Through Monday the 10th to Wednesday the 12th of August, we’re back to small, clean conditions (2ft to 4ft, 7 to 8 seconds). The winds remain cross-off and offshore, but the energy is dropping back down to 50 to 131. It’s not going to blow you away, but for a longboard or a twinny, it’ll be okay. A few ordinary waves to be had.

In short: there’s a massive flat spell right now until early August, then a brief but significant swell on the 7th for the experts, followed by a week of small but clean dribble. The standout is that Friday the 7th – the only true size in the whole outlook.

Stay patient, and keep watching the charts.

Rusty.
