The Lowdown
Alright, mates, Rusty here, and I’ve been staring at the charts for our patch. I’m not gonna sugarcoat it – it’s a grim outlook. The next sixteen days are looking like a write-off for any decent surf. We’re in for a proper flat spell.
It starts with a long wait. From the 30th of July through the 1st of August, there’s nothing worth talking about. Tiny, weak waves of 0.3ft to 0.5ft from the WSW and NW, with periods so short they’re just wind slop. The wind is messy, mostly cross-onshore, and the combined energy is pathetic, sitting at 7 to 9 (7-9). It’s a no-go.
Then we hit the big empty. From the 2nd of August right through the 11th of August, the swell just disappears. You get a few scraps of 0.3ft to 0.6ft, but the energy is almost zero, hitting single digits (1-2). The wind is often clean, and on the 5th of August afternoon we even get a glassy calm, but there’s absolutely nothing to ride. That’s a solid week-plus of nothing. The only blip on the radar is the 3rd of August, with a 0.6ft swell from the WSW and a period of 9 seconds, giving us a combined energy of 16 (16). Still too small to call it surfing.
The only, and I mean *only*, chance of a paddle comes right at the tail end. On the 12th of August, we see a tiny 0.6ft swell from the WSW with a period of just 4 seconds and a combined energy of 2 (2). The wind is light and cross-shore, so it’ll be clean but laughably small. The 13th and 14th of August are even smaller, with glassy conditions but waves that are barely a ripple over your ankle.
So, for the entire 16-day window, there are no standouts. No session to get excited about. If you’re absolutely desperate, the best of a very bad bunch might be the 3rd of August morning at Aberystwyth harbour trap (Wales). The swell is a weak 0.6ft from the WSW, but the period stretches to 9 seconds, giving it a bit more shape than the rest. The wind is a clean cross-offshore from the ENE, and the combined energy is 16 (16). But honestly, it’s still a knee-high novelty. Don’t hold your breath.
This is just a classic summer flat spell for this area. It’s a tough one, but things can change. For now, it’s a long wait for a proper wave.
Rusty.
