The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming up for The Reef in Culebra.
Honestly, mate, it’s a tough read for the next couple of weeks. We’re looking at a run of poor surf conditions that stretches all the way from now, Tuesday the 4th of August, right through to the very end of the 16-day window. There are really no standout sessions on offer here, so if you’re itching for a paddle, you might want to keep your expectations in check.
For the first week, the surf is tiny. Through Tuesday and Wednesday, we’re dealing with weak energy – the combined swell energy is barely crawling, sitting between 36 and 79. The swell height is under 3ft, coming out of the ENE, with a short, weak period of just 5 to 7 seconds. Winds are mostly cross or cross-off, but it’s not enough to make anything worthwhile. The water temperature is sitting at about 84°, which is pretty normal for this time of year.
Thursday the 6th through to Monday the 10th sees a slight lift in energy – we get into the low triple digits (113 to 166), but the swell stays small, between 3ft and 4ft, and still that short period around 6 to 8 seconds. Winds stay cross or cross-off, but the wave comment keeps calling it poor surf conditions. It’s just not coming together. If you’re a beginner, the small size is safe enough, but the quality isn’t there.
The second week, from around Wednesday the 12th of August onward, the swell actually starts to build noticeably. By Thursday the 13th, the combined energy climbs to 261 and the swell hits 6ft. Friday the 14th brings 6ft with energy up to 369, and by Saturday the 15th we’re seeing 7ft with energy at 489. That’s a solid, moderate wave energy pulse. The direction holds from the E to ENE, period slowly creeping up to 8 seconds. But here’s the kicker – the winds stay strong, around 18 to 22 mph, and they’re mostly cross or creating a lumpy cross-chop. For a reef break, that’s messy. At 7ft, this is getting into expert territory due to the power, but the lack of clean wind means it’s not a good bet. It’s actually the kind of setup that looks more interesting for kite surfing than paddle surfing on those bigger, wind-affected days.
After that, the energy tails off quickly. Sunday the 16th drops to 5ft and energy 171, and by Monday the 17th we’re back down to 4ft. The last couple of days, Tuesday the 18th and Wednesday the 19th, fade into tiny, weak surf again.
Overall, there isn’t a single day I’d point to and say “that’s the one.” The best on offer, relatively speaking, is probably the Friday the 14th or Saturday the 15th, when the swell is biggest, but the wind is going to ruin it. If you’re determined, those mornings might offer a cleaner window with cross-off winds, but it’s a long shot.
Stay patient, mate. It tends not to stay this flat and poor for long, and forecasts can change.
Rusty.

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.
