The Lowdown
Alright, Rusty here. Let’s take a hard look at what’s cooking for this stretch. We’ve only got one spot on the menu for the whole 16 days, and I gotta be straight with you – it’s a tough beat.
The whole window starts quiet and stays rough for a long stretch. For the first week, we’re looking at a run of poor conditions at Rabbit/Manana Island. There’s consistent swell, but it’s all cross and cross-onshore wind hammering it. The water temp is 81°, which is bang on average for the time of year – nothing unusual there.
The earliest any light appears is way out on Saturday, September 12th. That morning, the wind goes light and cross-off, and the swell sits at 6 ft from the ENE. It’s clean, with a long period of 12 seconds, and the combined energy reading is 782 (moderate). This is the one standout in the whole outlook – a proper groundswell with clean conditions. The crowds at this spot are sometimes a factor, so expect company. That ENE direction lines up nicely with what this break likes. For an intermediate, that’s a solid morning.
After that, the surf fades again. The morning of Monday, September 14th shows glassy conditions with a 4 ft ENE swell, period around 8 seconds, and a low energy reading of 241 (weak). It’s a small, clean dad-wave session. Not a standout, but a nice little window if you’re desperate for a float.
Beyond that, the wind picks back up and it’s back to messy, lumpy, cross-onshore junk through to the end of the forecast. No more standouts.
So, bottom line: if you’re hanging for something half decent, circle Saturday September 12th morning and maybe the 14th morning. The rest? It’s a write-off.
Rusty.
