The Lowdown
Alright, let’s get into it. The next 16 days are looking pretty grim for The Reef (Culebra). We’ve got a long stretch of nothing but poor surf, so let’s break it down.
The pattern is clear: we’re dealing with a persistent easterly trade wind setup that’s going to keep the ocean messy and the waves uninviting. The energy is weak, and the swell direction is just not working for this spot. It’s a reef break too, so when it’s cross-shore and lumpy, it’s not really a fun time. The water temp is 84°, which is about average for this time of year, so at least you won’t need a wetsuit.
From Tuesday afternoon through the following week, we’re looking at a gap with no real surf worth paddling out for. The swell is small, mostly under 3ft, with short periods around 6-8 seconds. The combined energy is weak, mostly in the 40s to 150s range. The wind is a problem, blowing cross or cross-off mostly, but it’s making things choppy. Don’t be fooled by the "clean" labels on some of the mornings; that’s just the cross-off wind, but the swell is still poor and weak.
By the time we get to the second week, around the 14th and 15th, the swell does pick up a bit, with heights over 5ft and even reaching 7ft. The energy jumps to strong levels, hitting 328, 349, 512, and 515. But before you get excited, the wind is still blowing strong and cross-shore, making it rough and lumpy. This is not the clean, powerful swell you want. It’s more of a messy, blown-out situation. On the 15th, it’s over 6ft, which is getting too big for beginners anyway, and with that cross wind, it’s only going to appeal to the experts, and even then, it’s marginal.
There’s a brief drop on the 18th, where the swell just vanishes, with only 0.7ft of wave and a long 10-second period. That’s a dead period. Then it comes back up a little on the 19th, but it's still nothing special.
Honestly, I can’t point to a single standout day here. The whole 16-day window is a write-off for decent surf. The break is very consistent, but the conditions are consistently bad. If you’re desperate, maybe the mornings on the 6th or 8th with a clean cross-off wind and waist-high waves might give you a few grovelly ones, but that’s scraping the barrel. The long-range stuff on the 14th and 15th has size, but it’s not going to be clean. With this much cross-shore wind and a beach/reef setup, it might be more interesting for the kite surfers than us paddle surfers.
It’s a poor outlook, plain and simple. Sometimes you get a blank run like this. It’s not unusual for the area. The swell direction is just wrong, and the wind isn’t helping. We’ll have to wait for the pattern to shift.

Information about the The Reef (Culebra) Surf forecast
The above surf forecast table for The Reef (Culebra) provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at The Reef (Culebra) can be found by selecting the local surf guide option on the grey menu. Our The Reef (Culebra) surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (The Reef (Culebra)) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
