The Lowdown

G’day, Rusty here. Look, I’ve gotta be straight with you – the next 16 days for Rabbit/Manana Island are a real battle. The wind is almost never on our side, and the surf quality is stubbornly poor. There’s no standout session, no magic window. It’s a tough run.

We start off on Tuesday, 21 July with a clear sky but a cross-shore breeze at 12 mph swinging cross-on. Swell is a weak 5 ft from the ENE at a short, choppy 7 seconds. The water’s sitting at 80°, which is about average for this time of year. The combined wave energy is a moderate 218, but the conditions are just messy. That afternoon, the wind picks up to 16 mph and goes cross-on, making it worse.

Wednesday 22 July is more of the same – winds are a fresh 22 mph, cross-shore in the morning, cross-on in the arvo. Swell bumps up slightly to 5 ft, but the period is still a short 7 seconds, giving us a lumpy, cross-chop. Energy climbs to 309, but it’s not doing us any favours.

Thursday 23 July sees the swell hit 7 ft, but it’s still that short-period ENE windswell. The wind is a fresh 22 mph cross-shore, so the surface is lumpy and messy. 360 energy, but it’s a write-off.

Friday 24 July brings rain showers in the morning and a strong breeze at 25 mph. The cross-shore wind is carving the surface up. Swell is 6 ft, energy 378, but it’s horrible.

Saturday 25 July looks similar – 7 ft swell, ENE, 8-second period, and a fresh cross-on wind. Energy hits 595, but it’s all wind-chop.

Sunday 26 July offers a tease: the swell drops to 4 ft, but the period stretches to a very long 16 seconds – that’s real groundswell. The energy skyrockets to 1119, which is strong. But the wind is still a fresh 19 mph cross-on from the NE, so it’s a lumpy, bumpy mess. That long-period swell needs a clean face, and it’s not getting it here.

Monday 27 July is the only day that gets a marginal score. Morning sees a 5 ft swell from the E with a 14-second period, and the wind is cross-shore at 19 mph. Energy is 1178. It’s still lumpy, but maybe, just maybe, there’s a half-decent wave in there if you’re desperate. The afternoon goes back to cross-on.

The rest of the run is a blur of fresh to strong cross-on winds, lumpy seas, and poor surf. From 28 July through to 5 August, every session is rated poor. The swell direction stays stubbornly ENE or NE, never matching the break’s optimum NNE direction. The wind never gives us a break.

There’s a brief moment on the morning of Thursday 30 July where the wind drops to a light 6 mph, but it’s still cross-on, and the swell is 6 ft from the ENE with a 10-second period. Energy is 755. Still marginal, still not worth paddling out for.

The long-range bits in the second week – like the 7 ft ENE swell on 4 August with a 13-second period and 1376 energy – are just more of the same: cross-on wind ruining the surface.

Honestly, if you’re a kite surfer, the strong cross-onshore winds and lumpy conditions might be your thing. For paddle surfing, it’s a long, bleak stretch. The only upside is that Rabbit/Manana Island is naturally exposed and fairly consistent, so it won’t stay this bad forever. Forecasts can change. But right now, I’d save your energy.

Rusty.

Information about the Rabbit/Manana Island Surf forecast

The above surf forecast table for Rabbit/Manana Island provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Rabbit/Manana Island can be found by selecting the local surf guide option on the grey menu. Our Rabbit/Manana Island surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Rabbit/Manana Island) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
