The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Fishermans (Rhiw). I gotta be straight with you, the next couple of weeks are looking pretty grim. The chart is a sea of flat lines and poor conditions, so we're in for a real dry spell. The water is sitting at 63°, which is a touch warmer than normal for this time of year, so at least you won't be freezing if you get in.
We kick off on Monday the 27th of July, and it's not pretty. Tiny swell around 2ft from the WSW, with a hopelessly short period of just 5 seconds. The wind is a nasty cross-onshore, making it choppy and messy. The combined energy is a pathetic 29 (weak). It's a no-go.
Tuesday the 28th sees a slight bump in size to 4ft from the SW, but the wind is still onshore, and the period is still a rubbish 5 seconds. The energy is still weak at 60. Not worth getting wet.
The rest of the week and into the first few days of August is a total write-off. Swell drops to nothing, barely 1ft, with periods of 4 or 5 seconds. The wind is either onshore or cross-shore, and the energy is basically zero. We're talking about a gap of several days here with absolutely nothing worth paddling out for.
Saturday the 8th of August is the only glimmer in this whole forecast. The morning is still a mess with a cross-shore wind, but the swell actually shows up. We're looking at 5ft from the west, with a period of 6 seconds. The combined energy jumps to 149 (moderate), which is the most we've seen all period. The real kicker is the Saturday afternoon session: the wind drops to glassy, and with that 5ft of west swell, it's the only time the report says "surfable waves." It's not gonna be a classic – the period is still short, and it'll be a bit fat and dumpy on the reef, but it's the only show in town. The water will still be a touch warmer than normal.
After that, it's back to the doldrums. The 9th of August has a fresh offshore wind, but the swell is gone again at 2ft, and the energy is weak. The rest of the run into the second week is just tiny, weak, and messy.
So, to sum it up: the one and only standout is the afternoon of Saturday the 8th of August. It's a long way off, so don't get your hopes up too much, but if that glassy wind and 5ft west swell holds, it's the only time you'll want to paddle out. For everything else, leave the board in the shed.
Rusty.
