The Lowdown
Alright folks, Rusty here. Gotta be straight with you – the next 16 days for Rabbit/Manana Island are looking pretty grim. I’m not seeing a single window where the stars align, and that’s a tough call to make.
The whole stretch is dominated by a persistent ENE wind that just won’t let up, keeping everything cross-onshore or cross-shore and messy. The water temp is sitting at 80°F, which is about average for this time of year, so at least you won’t be freezing while you’re getting frustrated.
We start off on Sunday, August 2nd, with a 7ft swell from the ENE, but that 25 mph cross-onshore wind turns it into a complete mess. The energy is moderate (847), but it’s not worth paddling out for. That pattern holds through the first week. Monday the 3rd has 5ft to 5ft, still cross-onshore and choppy. Tuesday the 4th sees the swell drop to 4ft to 5ft, and the period lengthens to 11 seconds, which would normally be a nice groundswell, but the wind is still cross-on, so it’s a choppy, energy-sapping session. The energy is moderate (379-452). Wednesday through Friday of that first week are just more of the same: dropping swell heights, short period, and onshore wind. The energy drops off to weak levels (78-97) by Friday the 7th.
The second week doesn’t get any better. From Saturday the 8th, the swell picks back up to 5ft to 6ft, but the wind stays strong, and the period is short at 7-8 seconds. The energy climbs back into the moderate range (237-349), but it’s all wind chop. The weekend of the 9th has a risk of thunderstorms on top of the messy surf. By the time we get to the 13th and 14th of August, the swell is solidly over 7ft, hitting 8ft in places, with strong energy (417-696), but it’s accompanied by a brutal 25-28 mph cross-shore wind. At 8ft, this is expert-only territory anyway, and with that wind, it’s just a washing machine. Honestly, the whole setup looks more interesting for kite surfing than paddle surfing.
There are no standout days here. Not a single moment where the wind goes light or offshore to clean things up. It’s a long, blank stretch. For an exposed spot like this, it tends not to stay this poor forever, but for this forecast window, I’d save your energy and wax. Check back with me later.
