The Lowdown

Alright folks, Rusty here. Let’s get straight into it for this stretch.

First off, I’m not gonna sugarcoat it – this is a tough outlook. We’re looking at a 16-day window starting now, and the first recommendation is essentially a no-go. For the first week, the combined swell energy is anemically low, reading between 0 and 7 (7 is weak), and the actual rideable wave heights barely register. It’s a long, flat spell. The first sign of anything that might be called a wave doesn’t show up until the 23rd of July, and even then it’s tiny. There’s a bare patch of several days there with no real surf to speak of.

The only spot on the radar is Fishermans (Rhiw). It’s a reef break that’s fairly consistent, but it’s not living up to that right now. For a beginner-friendly reef, it’s a shame, but the swell just isn’t there. Water temp is about average for the time of year, so nothing out of the ordinary for a wetsuit.

The best we’ve got in this whole period is a tiny window on the 25th of July. Saturday morning, we see a 2ft swell from the SW, with a short period of 5 seconds. The combined energy is still only 24 (weak). The wind is cross-off from the NNW at 19 mph, which will keep things clean. It’s small, but it’s the biggest bump in the whole forecast. The afternoon drops to 2ft, still clean. For a beginner break, this is about as good as it gets here, but it’s a far cry from a standout.

After that, it fades back into the doldrums. The 27th of July Monday morning goes glassy, but the swell is a pathetic 1ft at 5 seconds with 6 energy. It’s clean, but it’s barely surfable.

Bottom line: Don’t get your hopes up. The 25th of July Saturday morning is the only time you’d want to paddle out, and that’s only if you’re desperate or learning. The rest of the 16 days is a write-off for any decent waves. It’s just one of those spells.

Stay patient, Rusty.
