The Lowdown
Alright, Rusty here, havin’ a look at the charts for the next couple of weeks. Honestly, I’ve got to be straight with you—this is a tough one to get excited about. The whole 16-day window is one long, flat, and frustrating gap. There’s absolutely no surf on offer that’s worth paddling out for. The only spot in the mix is Fishermans (Rhiw), a reef break that’s rated as beginner-friendly, but the ocean just isn’t cooperating.
From Tuesday, July 21st, right through to Wednesday, August 5th, the swell is almost non-existent. We’re talking tiny dribbles of 0.3ft to 1ft at best, with the combined energy of all swells barely registering (1 to 36). The period is all over the place, but it doesn’t matter—it’s all too small. The water temperature is sitting at 63°F, which is a touch warmer than normal for this time of year with a 4°F anomaly, but that’s about the only interesting thing happening.
For a few moments, like Friday afternoon, July 24th, you get a glassy, flat ocean with a tiny 0.3ft, 13-second groundswell from the west (combined energy of all swells directed here: 4), but it’s just not enough to break properly. There’s a bit of a bump on Saturday, July 25th, with a 3ft, 4-second windswell from the WSW, but the wind is a lumpy 19 mph cross-onshore, making it a total mess. Later on, Sunday, August 3rd, there’s a brief moment of glassy conditions with a 0.7ft, 8-second swell from the WSW (combined energy of all swells directed here: 6), but again, it’s just flat.
This is a lean period for the area. It’s one of those blank runs that happens. The forecasts can change, but for now, don’t even bother waxing the board. The key takeaway: there is no standout, no hidden gem, and no reason to get wet. Save your energy.
