The Lowdown
Alright, folks, Rusty here. Let’s look at what we’ve got for the next 16 days. It’s been a quiet stretch, and unfortunately, we’re staring down the barrel of a long, slow run. The first real chance of a wave doesn’t show up until August 29th, so we’re looking at a solid 11-day gap with nothing worth paddling out for. Barely a ripple.
The first sniff of action comes Saturday morning, August 29th, at Surfside Jetty. We’re talking about a 3ft swell from the SSW with a 17-second period. That’s a proper long-period groundswell, meaning there’ll be energy in the water, but it’s prone to closing out on a beach break. The combined energy is moderate (624) and the water is a touch warmer than average for this time of year. The wind is light, coming cross-on from the SSW, so it’ll be a bit lumpy. The jetty can help focus that swell, but with the crowds *often* around and the break being inconsistent, it’s a gamble. The tide is a factor too, so it’s marginal. If you’re desperate, this is your window, but don’t expect perfection.
Sunday morning, August 30th, is a similar story: 3ft from the SSW, 15 seconds, and a bit more energy (461). Still light cross-on wind. It’s a repeat of the day before, maybe a touch smaller. Still marginal.
Looking further out, we get a weird shift on Tuesday morning, September 1st. The swell jumps to 4ft, but it’s from the WNW with a short, weak 7-second period. That’s windswell, not groundswell, so it’s all chop and no shape. The combined energy is moderate (465), but the quality is poor. The wind is light cross-on, but with that period, it’s a messy, bumpy affair. Not recommended.
The best of a bad bunch is probably Wednesday morning, September 2nd. A 2ft swell from the SSW with a very long 17-second period. The combined energy is moderate (492). The wind is light cross-on. It’s still small, and the long period means it’ll be a bit fat and slow, but it’s the cleanest option on offer. Still marginal.
Honestly, this is a tough run. The surf is small, the wind is rarely offshore, and the quality is poor. With the break being *inconsistent* and the crowds a regular thing, there’s not much to get excited about. For the next two weeks, keep your expectations low. If you’re a kiter, the moderate winds and decent swell energy on some days might look more interesting than it does for us paddle surfers.
Rusty.
