The Lowdown
Right, folks. Rusty here. Let’s be straight with you: for the next couple of weeks, Fishermans (Rhiw) is in a proper funk. We’re looking at a long, dry stretch with hardly a ripple worth paddling for. The first real hope doesn’t show up until Tuesday, July 28th, and even that’s a scrappy affair.
The big story is the huge gap. From now, Sunday the 19th, right through until Tuesday the 28th, it’s a flat-out, nine-day blank. No rideable swell, just tiny dribbles with periods as short as 3 seconds. The wind is mostly cross-off, which is a shame because there’s nothing to use it on. The water is sitting at a very warm 64°, which is much warmer than normal for this time of year, but that’s small comfort when there’s no surf.
Alright, the first sign of life comes on Tuesday, July 28th, morning. A weak SW swell pushes in at 3 ft, but it’s wind-affected with a short 6-second period from a fresh cross-shore breeze. The combined energy is weak (51), so you’re looking at lumpy, blown-out closeouts. The afternoon cleans up a touch with the wind going light onshore from the SW, but that swell drops to 3 ft and the energy ticks up to moderate (103). Still, it’s a messy, short-period swell – not a standout.
Wednesday the 29th sees the swell fade back to 1 ft, with a messy cross-shore wind and a period of just 5 seconds. Energy is pitiful (6). Not worth a drive.
Then, on Sunday, August 2nd, we get a tiny pulse. A 2 ft SW swell with a 5-second period arrives in the morning. The wind is a clean cross-off from the N at 12 mph, so it will be clean, but the combined energy is only 27 – weak. This is a knee-high dribble at best, with a short period that won’t hold open. The afternoon drops to 2 ft.
The best of a bad bunch is probably Tuesday, July 28th afternoon, purely because it has the most energy (103) with a 3 ft west swell. But it’s onshore wind and short period, so it’s a washing machine. If you’re desperate and have a beater board, you might find a few closeout wedges. For everyone else, this is a two-week write-off.
Rusty, signing off.
