The Lowdown
Alright, Rusty here. Let’s take a look at what’s happening at The Reef (Culebra). Right off the bat, I gotta tell ya, it’s a tough stretch ahead. We’ve got a long, long gap of flat or junky conditions before we see anything worth paddling out for.
The forecast kicks off Monday the 10th of August, but honestly, don’t even bother for the first week. From Monday through to the following Monday the 17th, the surf is mostly poor. We’ve got a bit of energy, but the wind is howling from the east and cross-shore, making a proper mess of things. Swell heights bounce around from a tiny 0.7ft up to 7ft on Friday the 14th, but with that wind, it’s just lumpy cross-chop. The combined energy hits a moderate 617 on that Friday morning, but it’s all for nothing with the conditions.
There is a little hint of something on Tuesday the 18th of August. The morning looks clean with a gentle cross-offshore breeze from the ESE. The swell is a meek 3ft from the ENE with a short period of 9 seconds, and the combined energy is only 202 – that’s weak to moderate. It’s surfable, and I mean *just* surfable. It’s the only window in the whole 16 days that gets a passable nod. This is a reef break, so it handles that short-period stuff a bit better than a beach, and with that light offshore wind, it’ll be glassy. The crowd situation? It’s “sometimes” busy here, so you might have a few friends out, but on a day like this, I wouldn’t expect a pack.
After that brief tease, it’s back to square one. From Wednesday the 19th right through to the end of the forecast on Tuesday the 25th, the swell totally drops out or gets hammered by strong winds. We’re talking tiny 0.3ft to 3ft waves with poor conditions. The wind cranks up again on Monday the 24th with a near gale from the NNE at 31 mph – that’s a blown-out mess if I’ve ever seen one.
So, the only standout, and I mean your *only* real shot, is Tuesday morning the 18th of August. It’s not gonna be epic, but it’ll be the cleanest wave of the month. If you’re keen, that’s your session. Otherwise, it’s a long two weeks of watching the ocean do nothing good.
Rusty.
