The Lowdown

Alright, gather 'round and listen up. Rusty here, lookin' at the charts for the next couple of weeks. I gotta be straight with you, it's a rough stretch.

First thing you need to know: the water's sitting at 80°F, which is pretty much spot on for this time of year, so no surprises there.

The pattern is stubborn. For the next ten days, we're staring down the barrel of a strong, persistent trade wind setup. That ENE flow is just relentless, and it's wrecking what could be some decent swell. The whole period is a grind of lumpy, cross-onshore, messy conditions. The swell energy is there, sure, but it's all wind-chop. We're looking at a solid block of poor surf from now all the way through to the 4th of September, with energy readings climbing from 377 up to a massive 1464 by the afternoon of the 4th, but it's all blown out.

Then, on September 5th, things get interesting, but intense. That Saturday morning, the swell pumps up to 10ft at 9 seconds from the E, with a huge energy reading of 1490. The wind is a cross-shore from the E at 19 mph. The notes say the swell might be too big for this break, which is Rabbit/Manana Island. That's a big call. For experienced surfers only that morning. The afternoon cleans up nicely with a gentle cross-offshore breeze, but the swell drops to 8ft. It's a short window. The next day, the 6th, has a bigger groundswell of 7ft at 12 seconds, but the wind is back on it, turning it lumpy again.

The real standout, if you can wait, is Tuesday, September 8th. The morning is a write-off with a howling onshore, but the afternoon flips completely. We get an 8ft swell from the E, and a gentle offshore wind from the SSW. That's the magic combo. The guidance says it's excellent for experienced surfers. That's our best bet, but it's a long way off, so take it with a grain of salt.

The morning of September 9th also looks tidy with a 7ft swell and a cross-offshore breeze, but it's a quick window before the trades return.

After that, from the 10th onwards, it's just a slow fade-out. The swell drops, the wind stays messy, and the energy readings fall back to the 200-500 range. A real bummer of an end to the forecast.

It's a grind, folks. The only real hope is that Tuesday the 8th afternoon window. Mark it, but don't book the trip just yet.

Rusty.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Rabbit/Manana Island may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
