The Lowdown
Alright folks, Rusty here again. Let’s lay it out plain and simple for the next couple weeks. It's all about The Slot, and honestly, we're gonna have to pick our moments.
The first real window is Tuesday morning, September 8th. We're looking at waves around 3ft from the south, with a 12-second period. It's dead flat glass, with a light breeze, so the surface is going to be clean. Water is reading 61°, which is a touch warmer than normal for this time of year. This is the best clean look we've got early on. The afternoon goes marginal, so the early session is the one.
From Wednesday the 9th through the weekend, it gets smaller and choppier. There’s some long-period energy (19-second swells) but the height is tiny, only about 1ft to 3ft. It's not going to have any power. Winds turn cross-onshore or even strong cross-shore, especially on Saturday the 12th when it blows 25 km/h. Sunday afternoon brings a bump to about 5ft, but it’s short-period windswell, and it'll be a washing machine. That whole stretch from Saturday midday through Sunday afternoon is a complete mess. If you've got a kite, this might be more your speed.
Monday the 14th, things calm down. There’s a glassy morning with 4ft waves from the west-northwest. The period is short, only 8 seconds, so it won’t be the most powerful, but the clean conditions will make it workable.
Looking way out, around the 21st of September, there’s a hint of something better on the horizon. It’s a long way off, so don’t get too excited, but there’s a forecast for a glassy morning with 3ft waves, a long 17-second period, and moderate energy. On a reef, that long period is a huge plus for shape, but with that size, it could be pretty soft. It’s a promising thought, but treat it as a “we'll see.”
The days in between are mostly small and junky. Waves hover around 2ft to 3ft with a lot of cross-onshore wind. You'll have to be a detective to find a clean one.
So, my call: Get out there Tuesday morning (Sept 8) for the best early surf. The morning of the 14th is your backup plan. That 21st date is a long-shot dream that might just line up, but let’s not count on it just yet.
Keep an eye on the ocean.
Rusty.
