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.

A general guide to surfing at Rabbit/Manana Island can be found by selecting the local surf guide option on the grey menu.

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.
