The Lowdown
Right, pull up a stool, grab a coffee. Rusty here, and I've been staring at the charts for The Reef (Culebra) for the next couple of weeks. Got to be straight with you – it's a bit of a frustrating picture for this spot.
Alright, let's look at the overall pattern. Right now, there's barely a ripple. It's dry. We're looking at a long stretch of tiny, useless surf from today through the first week of September. The water's sitting at a warm 85°, which is about normal for this time of year, so that's a small comfort, but the waves just aren't there. We have a big gap of no recommendations for over a week. Then, there is a brief moment of hope around the 10th of September, but the whole run is plagued with onshore or cross-off winds and the quality is just not there for a good paddle session. It's a tough one.
The only real pulse of energy comes on Thursday, September 10th. For the morning session, The Reef will see some head-high to maybe a foot overhead swell pushing in from the East at 6 ft with moderate combined energy (417). That's the biggest we see, but we’re dealing with a short-period swell of only 7 seconds which makes for weak, lumpy waves. Plus, there's a fresh cross-off breeze from the ESE, which will keep the surface clean, but the wave shape will be disappointing. It’s a shame, because that pulse has some energy in it, but the quality is poor. To be honest, with that wind and a short-period, messy swell, this setup looks a lot more interesting for kite surfing than a proper paddle session.
Sunday, September 6th is the next best, but that's only a slight improvement. You're looking at chest-high waves from the East, 4 ft in the morning with a long period of 10 seconds, giving that pulse some proper energy (301). The wind is cross-off from the SE, keeping it reasonably clean. It's described as marginal though, so don't get your hopes up. It might be okay for someone who just wants to get wet.
The rest of the run is flat. From now right through until that 6th of September, it's tiny, and then after that 10th pulse, it drops straight back into the doldrums. If you're after a proper surf, this isn't the window for The Reef. Sometimes you get these blank runs and it's just how it is here.
Stay tuned, forecasts can change, but for now, maybe find something else to do with your time.

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.
