The Lowdown
Alright, let’s get into it. To be straight with you, the next couple of weeks are looking pretty grim for The Reef (Culebra). We’re looking at a run of small, weak surf with a lot of cross-shore wind messing things up. There’s really nothing on the table that’s going to get the heart rate up for a while.
The first stretch, through the coming week, is mostly about tiny, short-period swell. We’re talking around 1ft to 4ft, with periods mostly in that 5 to 9 second range – just not enough push or shape. The wind is mostly cross or cross-off, which keeps things clean at times, but the waves are just too small and gutless to bother with. The shelter here means we’re not seeing any real size, and the energy is weak, with combined swell energy often in the 20s, 30s, or 60s. It’s a whole lot of nothing.
There’s a slight bump in energy around the 27th and 28th where the combined energy gets up into the 140s, 150s, and even 217 on Monday the 28th morning. But the wave height is still only 2ft to 3ft. Yeah, there’s a bit more push in the water, and the period stretches to 10-12 seconds which gives it a touch more quality, but it’s still well below what you’d call a surfable wave here. That NNE/N direction is also not ideal for this spot; it’s exposed to the north, but it’s just not lining up.
To be honest, the only time things look halfway decent is Thursday the 24th afternoon. We get a bit of offshore wind, clean conditions, and a small 2ft swell from the ENE. It's surfable, but “very ordinary” is about the best you can say for it. It’s one for the longboard or a SUP if you’re desperate, but it’s not going to be memorable.
After that, we’re back into the same pattern of small, weak, cross-shore surf right through to the end of the forecast. Nothing on the horizon that suggests any real groundswell filling in. It’s a flat, quiet spell for this stretch of coast.
So, bottom line: if you’ve got better things to do for the next couple of weeks, go do them. The Reef (Culebra) is going to be a whole lot of looking at the ocean and not much riding. I’ll be keeping an eye out, but this one’s a write-off for now.

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.
