The Lowdown
Right then, let’s have a look at what’s on the cards for Culebra. The Reef is a very consistent spot, exposed to the north, and it takes a solid east-northeast swell to really fire. Over the next 16 days, we’re looking at a pretty grim run, to be honest. The wind is mostly a problem – a persistent easterly breeze, often cross-shore, keeps things lumpy and messy. There’s a real gap in quality surf on offer here.
The first sign of anything worth a paddle is not until Tuesday, the 18th of August. The swell is tiny, just 2ft from the east, but the wind swings around to a light sea breeze and then goes light offshore on the Tuesday afternoon. The conditions turn clean. The combined energy of all swells directed here is weak (158), so it’s not going to be powerful, but for a small-wave session, it’s the cleanest it gets. The water temperature is about average for the time of year.
Then it pretty much drops off again. The rest of the week into the weekend is small, with poor surf conditions and messy cross-shore winds. The swell is too small and the wind too strong to make anything of it.
So, the standout, if you can call it that, is the afternoon of Tuesday, 18th August. The Reef (Culebra) will have tiny, clean waves. It’s nothing to get excited about in terms of size, but it’s the only window where the wind behaves. The rest of the period is a write-off for decent surf. If you’re desperate for a paddle, that’s your only real shot.
