The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’.
So, we’re looking at a pretty drawn-out run of small, weak swell. The wave energy is low, around 265 (combined energy of all swells directed here) on Wednesday, and it barely gets its head above water for the next week and a half. The water is a balmy 73°F, which is 7°F warmer than normal for this time of year – that’s pretty unusual, feels more like a bath than the ocean.
We’ve got a solid gap of poor conditions at the start. The first real glimmer of something decent won’t come until Saturday morning, September 19th. That’s a full 10 days away, so we’ve got a long stretch of flat, junky surf to get through. The mornings are your only real chance, as the afternoons are mostly blown out by onshore westerlies.
Topaz Street is the only break on the cards. It’s a beach/jetty setup, fairly consistent but on the beginner side. The swell is tiny, 2ft from the SSW, with a very long period of 18 seconds. That long period is a double-edged sword here – it’ll have some push, but it’s prone to breaking a bit straight and fat on a beach break. The real standout window is the morning of Saturday, September 19th. The wind goes glassy, dead calm, and the combo of that clean face and the long-period groundswell should make for the cleanest, most user-friendly waves of the whole forecast. The crowd potential is there, but it is what it is.
The next best window is the morning of Monday, September 21st. The swell bumps up to 3ft from the SW, with a solid period of 17 seconds, and the combined energy climbs to 401 (combined energy of all swells directed here). The wind is a clean cross-offshore from the SE, which will keep the faces tidy. This is a slightly bigger, more energetic option than the 19th, but still small. It’s the best of the second week, but it’s a long way out and the models might shift.
For the rest of the run, expect mornings with tiny, weak swells and cross-off breezes, but the afternoons are a waste of time. The setup is more interesting for a kite surfer than a paddle surfer on most days.
Rusty.
