The Lowdown
Alright, Rusty here. Let's talk about what's happening at The Reef in Culebra.
Honestly, it’s a pretty grim stretch ahead. We’re looking at a long, long run of flat or poor conditions. The surf just isn't cooperating for paddle surfing. There's a big gap of days with next to nothing rideable.
The first real pulse of energy shows up around Friday morning, August 14th. We get a bump of 6ft from the East, but it's got a short, weak period of just 7 seconds and the wind is a nasty cross-shore, making it lumpy. The combined swell energy is moderate, around 410, but it’s messy. This is a beach and reef setup, and with that wind, it’s honestly more interesting for a kite surfer than for a surfer.
This pattern of poor quality continues straight through the weekend. By Sunday, August 16th, the swell is trying to push 8ft from the East, but with a 25 mph cross-shore wind and storm risk, that’s expert territory only, and even then, it’ll be a washing machine. The energy is strong at 627, but it’s just not surfable.
We finally get a break from the wind on Monday the 17th, with a clean, cross-off breeze, but the swell completely vanishes, dropping to 1ft. It stays tiny for days.
The only thing that looks even close to a standout, and I'm using that term loosely, is around Tuesday, August 25th. We see 5ft swell from the East, with a period of just 6 seconds, but the wind turns cross-off and clean. The energy is moderate at 166. It’s still short-period chop, but at least the surface will be clean. The Reef is very consistent, so it's a spot that usually has something, but the quality is poor throughout the entire 16 days. For this area, a blank run like this can happen, but it tends not to stay poor for long.
Keep your eyes peeled, but for now, the boards are staying in the car.

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.
