The Lowdown
Alright crew, Rusty here again. Let’s break down the same stretch but in feet and knots.
Things are looking rough for Rabbit/Manana Island. Starting Thursday, September 3rd, there’s a messy cross-onshore breeze blowing at 25 knots from the ENE. The swell is a lumpy 7ft from the same direction, but with a short, weak period of only 7 seconds, and the combined energy is a moderate 561. It’s just poor, choppy water – not worth the hassle.
That same brown-soup pattern drags through Friday, Saturday, and into Sunday, September 6th. The wind eases a bit, but stays cross or cross-onshore, keeping the surface bumpy. Water temp is about 80°, which is normal for the season. Nothing to write home about.
Now, Monday, September 7th, the swell really starts to pump. The afternoon shows a solid 10ft from the ESE, with a period of 8 seconds and a very strong combined energy of 1886. The wind actually turns cross-offshore and cleans it up, but here’s the catch – it’s flagged as too big for this break. That’s expert-only territory, and even then, it’s a gamble. Not for the average surfer.
Tuesday, September 8th, is the one bright spot. The morning offers a 5ft ENE swell, with a decent 11-second period, and the wind shifts to a clean offshore from the S at 15 knots. The combined energy is a moderate 664, and conditions are expected to be very good. This is your best bet. The afternoon drops to 4ft and lighter offshore wind, but still clean. If you’re picking a session, this Tuesday morning is it.
After that, it’s back to the grind. From Wednesday, September 9th, through the end of the forecast, we’re looking at a mix of poor-to-marginal conditions. The swell pulses up again with some long-period energy (12-14 seconds) around the 11th and 12th, bringing 6ft to 7ft swells, but the wind is cross or cross-onshore, so it’s lumpy and messy. The final week is more of the same – moderate energy, short periods, and onshore breeze. There’s a brief flicker on Friday, September 18th, with a 3ft, 12-second swell and light cross-shore wind, but it’s only marginal.
Bottom line: the first week is mostly a washout. If you’re itching for a paddle, get out Tuesday morning, September 8th, for the cleanest, most rideable waves. After that, it’s a long wait for anything half-decent.
Rusty.
