Table - best surf conditions forecast for The Reef (Culebra) over the next 16 days.
Alright, Rusty here. Let’s be real about the next 16 days for The Reef in Culebra. It’s a grim outlook, plain and simple. This reef break is usually reliable, but the wind is going to ruin the party. There’s a constant, stiff breeze out of the east or east-southeast, either cross or cross-off, just tearing up the surface. The water is at 83°F, which is right around average for this time of year, so that’s not the issue.
Starting Sunday, July 12th, and through the whole first week, it’s just bad. The combined swell energy is weak, like 108 on Sunday morning, and the swell is a short-period, wind-blown 4ft from the east. A 30 km/h cross-shore wind is making it lumpy and choppy. It’s all “poor surf conditions,” and that’s the truth.
We get a little pulse around July 18th. On Saturday the 18th, the combined energy hits 156, with 5ft of east swell and a 6-second period. The wind is still a fresh 30 km/h, but it’s cross-off, so the surface might be a bit cleaner. The swell direction is east, which isn’t the optimum north swell for this spot, so the shape won’t be great. Still a fresh breeze, so no glassy conditions. This is the best of the worst.
The strongest push is on July 20th. Monday shows 5ft of east swell with a 7-second period, and the combined energy is 247. That’s moderate energy, but it's still short-period. The wind is a moderate 25 km/h cross-shore, so expect lumpy, choppy waves. The swell is over 5ft, so it’s not for beginners, but it’s not huge. Tuesday the 21st drops off fast to 3ft.
After that, it’s a long, dead gap from the 22nd through the 27th, with tiny, weak swell and strong, messy winds. The whole setup is better for a kite than a paddle.
The only days you might even consider it are the 18th, 19th, and 20th of July, and even then, it’s a compromise. The conditions are poor, the wind is a problem, and the swell direction is off. It’s a dry spell for this area, and it’s going to stay that way.
