The Lowdown
Alright, Rusty here again. Let’s break it down for The Reef in Culebra. I gotta be honest, it’s a grim forecast. This spot is usually reliable, but for the whole 16-day window, there’s nothing but poor surf conditions on the cards.
We start on Wednesday afternoon, August 5th. The swell is a weak 2.6 ft from the NE, with a short period of 6 seconds, and an onshore cross wind ruining what little shape there is. The energy is barely there (53). That’s the story for a while. We’re stuck with a steady easterly breeze, often 15-20 mph, keeping the surface lumpy and cross-chop. The swell sits between 3.3 ft and 4.3 ft through the first week, but it’s all short-period, weak energy from the NE and E. The water is a warm 84°, which is about average.
The only real change is when the swell size picks up. By Thursday the 13th, we see 5.9 ft, and by Friday the 14th, it hits 6.9 ft from the E, with the energy jumping into the strong range (488). But that’s still blowing 22 mph cross, so it’s messy and lumpy. That size is for experts only. This pattern of bigger but choppy surf continues through the weekend and into the next week, with wave heights between 5.9 ft and 6.6 ft and high energy (400-500), but the wind never cleans it up.
By the 20th, the swell tanks to a tiny 1.3 ft with almost no energy (29). With constant cross winds and poor quality, this whole run is a bust. To be honest, with that wind and chop, this setup looks way more fun for kite surfing than for a paddle out. There’s no standout day here.
