The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Fishermans (Rhiw). I gotta be straight with you, it’s looking like a tough run.
The water temp is sitting around 63°, which is a touch warmer than normal for this time of year, so at least the wait won’t be a cold one.
Over the next week and a half, we’re looking at a proper dry spell. From now through until around the 31st of July, there’s nothing doing – just flat, weak dribble with scores of zero across the board. Winds chop and change, but with no swell to work with, it doesn’t matter. There’s a couple of glassy mornings, but on a flat ocean, that’s just a good day for a paddle, not a surf.
We finally get a pulse of something on Saturday the 1st of August. The morning is still messy with a light cross-onshore and tiny 1 ft swell, but the afternoon shows a bit more life. Swell jumps to 5 ft from the SW with a short, weak period of 5 seconds, and the combined energy hits a moderate 126. The wind goes cross-off from the NNW, so conditions should be clean. But that short period means it’ll be a bit lumpy and weak – it's a beginner-friendly height, but don't expect much push.
Sunday the 2nd of August sees the swell drop back to 2 ft with onshore winds in the afternoon, so that window of surf is pretty narrow.
After that, it’s back to tiny, weak junk for the rest of the outlook. There are a couple of clean, glassy mornings on the 3rd of August and the 7th of August, but with swells under 2 ft and energy readings in the single digits, there’s just nothing to surf.
Honestly, the only real standout window in the whole 16-day period is that Saturday afternoon, 1st of August. It’s not going to blow anyone away, but it’s the best we’ve got. If you’re a beginner looking for a clean, manageable wave, that’s your shot. Anyone else might want to save the energy.
Rusty.
