The Lowdown
Right, grab a coffee, 'cause I'm gonna level with you. The Reef (Culebra) is our only game in town for the next 16 days, and honestly, it's a rough stretch. The pattern is one of long, drawn-out flatness. We've got a bit of a pulse right at the start, then nothing but tiny dribble for a solid week and a half. A blank run like this is pretty normal for the area when the trade winds lock in and there's no solid north or north-east groundswell in the mix. The water's sitting at a warm 85°F, which is about average for this time of year, so at least you won't need a thick suit.
Sunday morning kicks things off with the best we'll see. Swell is a messy 5ft from the NE at a short 8 seconds, but the energy is moderate at 380, so there's something to push around. The problem is a 16 mph NE wind is blowing cross-onshore, making for some real choppy conditions. It's not great, but it's the biggest it's going to be. By Sunday afternoon, the wind swings SSE and goes offshore, cleaning it right up. The swell bumps up to 7ft from the ENE with a slightly better 10-second period, and the energy jumps to 880. That's a notable pulse, but it comes with a "risk tstorm" warning, so you'll be dodging rain. That afternoon window is the standout of the entire forecast, but it's still a marginal call with questionable tide.
From Monday morning, the 31st of August, it's a steep drop-off. Swell sizes sink below 5ft, and by Tuesday the 1st of September, we're looking at waist-high slop and smaller. The wind stays moderate and mostly cross-off or cross, keeping the surface clean enough, but with combined energy dropping to two-digit figures like 42, there's just no grunt. The following week, through to the 14th of September, is a write-off. We're talking ankle-snappers with swell heights under 2ft and energy readings mostly below 100. The wind remains a steady fresh breeze from the ESE, keeping things clean but offering no power. There's a tiny flicker on the 11th of September with energy creeping up to 144, but at 2ft, it's still a knee-high dribbler.
So, the one true standout is Sunday afternoon, the 30th of August. The Reef will have some size, the wind will be offshore and clean, and it's a very consistent reef setup. But it's only for intermediate and above; that 7ft swell is solid. For the rest of the 16 days... leave the board at home. If you're absolutely desperate, the clean but tiny conditions from Monday the 31st onwards might be okay for a longboard and a lot of patience, but don't expect any real waves.

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.
