The Lowdown
Alright folks, Rusty here. Time to look at what’s coming down the pike for The Reef at Culebra.
Honestly, it’s a pretty quiet picture across this whole 16-day window. We’ve got a long stretch ahead with no real standout swells, so we’re looking at mostly small, weak, and choppy conditions. The first actual surf recommendation doesn't pop up until September 1st, and even then, the energy is only at a weak 47. The water temp is sitting around 85°F, which is about average for this time of year.
Let’s break it down. From Tuesday the 1st through Thursday the 11th, it’s a grind of small, weak surf. The swell never really gets above 4ft, with periods shorter than 8 seconds, so the energy is mostly in the double digits to low triple digits. The wind is almost always a cross or cross-off breeze from the east or southeast at 12 to 19 mph, which means it’s going to be a bit bumpy and not very clean. The best part of this stretch is that the cleanest conditions pop up on a few mornings with the cross-off breeze.
Now, for those paying attention, the surf does show a pulse around Thursday the 10th of September. We see a 6ft swell from the east on Thursday morning, with a combined energy of 259. The wind is cross-off and clean, but the period is short, around 6 seconds. Later that afternoon, it drops to 5ft but the period bumps up to 8 seconds, giving us 338 energy. That’s moderate wave energy. While the size might be tempting, the short period and the cross-shore wind mean the shape won't be anything special, so I wouldn't call it a standout.
Then, there’s a little spike in energy on Wednesday the 16th of September. The morning shows a 4ft east-northeast swell with a 9-second period and a combined energy of 335. The wind is cross-off and clean, which is good, but the swell is still fairly short-period and the wind is cranking at 19 mph. It’ll be a bit of a battle for the takeoff.
Overall, the best bet, if you’re desperate, would be the morning of Saturday the 5th of September. We’ve got a tiny 3ft swell from the east, but the period is only 8 seconds, so it’s not going to have much push. The wind is cross-off and clean, which is the one major positive. It'll be a tiny, clean wave for a log or a mid-length, but not much else.
The truth is, there’s one day that stands out as the best on offer. If you’re an intermediate surfer looking for a cleaner wave, focus on Wednesday morning, September 16th. The 4ft swell from the ENE with a 9-second period and combined energy of 335 is the biggest, cleanest window we get. The cross-off breeze at 19 mph will make for a bumpy surface, but the clean conditions out of the ESE could offer a few better lines. It’s not classic, but it’s the pick of a pretty limp bunch.
So, no real fireworks for Culebra in this outlook. Keep an eye on the charts, but don’t bet the farm on this one.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
