The Lowdown
Alright folks, Rusty here. Let’s get straight into it. We’re looking at Rabbit/Manana Island, and I gotta be honest with you – it’s a tough stretch ahead. The entire 16-day window is looking pretty grim. There’s no standout, no real window where everything clicks. The wind is a problem, the swell is messy, and we’re coming up empty.
The water is sitting at 79° on the first day, which is about average for this time of year, so no surprises there.
From Wednesday the 15th right through to the 29th, it’s a long, dry spell. The surf is there, but it’s poor. We’re seeing a constant cross-shore or cross-onshore wind, mostly from the ENE or NE, blowing at 9 to 22 mph. That’s going to keep the surface chopped up and lumpy. The swell is small, mostly around 3 ft to 5 ft, with a short period of 6 to 8 seconds – that’s just windswell, bumpy and weak. The combined energy stays in the low to moderate range, mostly between 134 and 385, which tells you there’s not much grunt in the water.
There is a little flicker of hope way out around Sunday the 26th. We get a long-period groundswell sneaking in from the E at 4 ft to 4 ft, with a period of 16 seconds. That’s proper energy, and the combined energy jumps to 714 and 819 – that’s a solid push. But here’s the catch: it’s still cross-on or cross-shore wind at 15 mph, so the surface won’t be clean. That long period will also make it break straight and close out on a beach break. Rabbit/Manana Island is exposed, and a NNE swell is the optimum, but this is coming from the E. It’s a marginal call at best, and the forecast gives it a low score. It’s a shame, because if the wind was offshore, it could be a fun session.
The 30th is similar – a bit of ENE swell, but again, cross-shore wind and a short period of 6 seconds. It’s just not clicking.
Honestly, there’s nothing here I’d recommend paddling out for. The setup is more interesting for kite surfing than paddle surfing given the persistent cross-breeze and bumpy surf. A blank run like this can happen, but forecasts can change, so keep an eye on it.
Rusty.
