The Lowdown
Alright, Rusty here again, switching it up to feet and miles. It's a grim outlook for Rabbit/Manana Island over this stretch. Basically nothing worth rushing out for.
Tuesday, September 8th, has our best shot with a 6 ft swell from the ENE and offshore winds from the SSW at 19 mph in the morning, giving us a clean window. Combined energy is moderate at 799. Water temp is average for this time of year at 81°F, nothing strange there. Still, the surf is marginal and tricky with the tide.
From Wednesday the 9th, it's all downhill. The whole week through the 15th is a write-off – onshore slop, cross-chop, and dwindling swell. Winds are fresh and gusty, and wave heights drop below 3 ft. Not worth your time.
A bit of energy returns around September 17th with a 5 ft swell from the ENE and combined energy hitting 593, but it's still blowing 19-22 mph cross-shore. The quality is total trash – "lumpy cross-chop" is the phrase. That pattern holds through the 20th. This is more of a kiteboarding setup than a surf one.
The final days, September 22nd and 23rd, bring a 2-3 ft, long-period groundswell from the NNW with 13-15 second intervals, but the wind hasn't let up – 19-22 mph cross-on from the ENE, trashing any potential. No standout sessions anywhere, folks.
Keep the board bagged up. It'll turn around eventually.
Rusty.
