The Lowdown

Alright, this is Rusty. Let's be straight with you – the next couple of weeks aren't looking great for a paddle. We've got a solid 16-day window here, but the first real surf worth talking about doesn't show up until Monday the 3rd of August. Before that, it's a whole lot of nothing – tiny, weak, and messy. From Thursday the 30th right through Sunday the 2nd, the swell is miniscule, with heights barely scraping 2ft and combined energy struggling to hit double digits (3-15). The wind is all over the place, mostly cross or onshore, so it's a flat spell you'd be better off spending doing something else.

So, the only spot on the cards here is Fishermans (Rhiw). The water is sitting at 62°F – a touch warmer than normal for this time of year, which is a nice little bonus.

The first hint of something rideable comes on Monday the 3rd. The morning sees a 1ft SW groundswell with a 9-second period, so there's a bit of push behind it. The combined energy jumps to 32, which is still weak but a clear step up from the flatness. The wind is a light breeze from the ENE, blowing cross-offshore. That's clean. The afternoon holds similar 1ft swell from the WSW with 30 energy and a light N breeze. It's still tiny, and the spot is a reef that's fairly exposed to the SW, so it'll be small and clean but not exactly firing. It's a beginner-friendly wave, so for the absolute beginners, this is your window.

Tuesday the 4th is much the same story – 1ft, 8-second SW swell, light winds. The combined energy drops back to 16 in the morning. It's a consistent, clean option for a learner.

Wednesday the 5th is a standout in this otherwise bleak run. The morning brings a glassy, near-flat ocean with a 1.0ft SW swell. The combined energy is only 9, but the wind is a whisper from the SSE – glassy. That's a rare treat. The afternoon stays clean with a light cross-off breeze. For a tiny wave, you can't ask for better conditions, but it's still small.

After that, from the 6th of August onward, it really falls apart. The swell gets smaller and the wind gets stronger. By Thursday the 8th, we're looking at onshore gales hitting 19-22 mph with zero swell. The combined energy drops to zero. It's a total write-off. The wind is fresh and onshore right through to the 14th, with only a few moments of clean, cross-off wind on the 12th afternoon, but even then, the swell is only 1ft and the energy is a measly 7. It's just not happening.

Overall, the best on offer is the Monday 3rd through Wednesday 5th, but even that is for the absolute beginner or someone who just wants to be in the water. If you're looking for anything with real push, you're out of luck. This is a tough stretch.

Rusty.
