The Lowdown
Alright, this is Rusty. Let's get real about the waves coming up. I'm looking at the whole forecast and, honestly, it's a tough one for Culebra. The entire 16-day window is a bust. There are zero surfable options on offer. Not a single decent wave in sight.
We're looking at a massive gap of flatness from now all the way through the forecast period. The swell energy is barely registering. For instance, on Saturday afternoon, the combined energy of all the swells coming into The Reef is a weak 55, and it only goes downhill from there. Most days, you're seeing energy readings that are more like a washing machine than an ocean swell – stuff like 57, 64, and even dropping to a pathetic 9 at one point. The swell heights are tiny, mostly floating between 0.3 ft and 2 ft, and the periods are either short or come from directions that don't match up with The Reef's north-facing exposure. The winds are cross-off, sure, but with barely any swell to work with, clean surf conditions just mean clean flat water.
It’s a blank run, and honestly, for this area, that's not unheard of. It tends not to stay this poor for too long, and forecasts can change, but right now, there's nothing to recommend. Don't even bother paddling out; it's a write-off until something changes.
Rusty.

Further information to help with frequently asked questions about our surf forecast for The Reef (Culebra) may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
