The Lowdown
Alright, grab a seat and listen up. I'm lookin' at the next couple of weeks here, and I gotta be straight with you – it's a tough stretch. The good news is, we've got one break that's our best bet, but you're gonna have to be patient. We're talking about The Reef (Culebra).
Right now, water temp is sitting at 84°F – that's about normal for this time of year, so no surprises there.
The first few days are a write-off. We're looking at tiny, weak waves with poor surf conditions. The wind is mostly cross or cross-off, but the swell just isn't there. Wednesday afternoon through to the following Monday morning is all flat and messy. You'd be better off doing something else.
Around Sunday, August 30th, things start to get interesting. We've got a moderate swell energy (527) building with a 5ft swell from the ENE. That's a solid size, but it's a short period (9 seconds) and the wind is cross-shore, which will chop it up. It's still a "poor surf conditions" call, so don't get too excited. The afternoon of the 30th is the only flicker of hope, with a "marginal" rating. Swell drops to 4ft, still from the ENE, but the period stretches to 11 seconds and the wind goes cross-off, cleaning it up. The Reef is a consistent spot, and it's exposed to the north, which is the optimum direction. The combined energy is moderate (372), so there's some push. But the quality is still a question mark.
After that, it's back to small and weak for the rest of the run. There's nothing else that stands out.
So, here's the deal: The only real shot to get wet is the afternoon of Sunday, August 30th, at The Reef (Culebra). Expect 4ft from the ENE with a cross-off wind. It's not a classic, but it's the only game in town. Be ready for it, but don't hold your breath for the rest of the month.

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.
