The Lowdown

Alright, grab a coffee and settle in, ‘cause the next couple of weeks here in Culebra are looking like a bit of a mixed bag, and honestly, a little frustrating at times. We’ve got some swell on the horizon, but the wind is going to be a constant battle, keeping things from really cleaning up as much as we’d like. The first few days are a write-off, with hardly any energy and then when the swell does show up, it’s often coming with a messy cross-shore or onshore breeze. It’s not a total disaster, but you’ll need to pick your moments.

The only real break on the menu is The Reef (Culebra). It’s a very consistent reef setup that’s exposed to the north, so it catches a bit of everything. The water temp is sitting right around 84°, which is bang on average for this time of year, so no surprises there.

Right out of the gate, Tuesday the 11th is a no-go. We’ve got a risk of thunderstorms and a stiff 19 mph cross-shore wind just ruining any chance of clean surf. Swell is a pathetic 5 ft from the ENE with only a 6-second period, and all that combined energy is a weak 166 – just not worth paddling out for.

Wednesday and Thursday the 12th and 13th are even smaller – we’re talking ankle-snappers of 0.6 ft to 1 ft. The wind eases up enough to be cross-offshore in the mornings, making it glassy clean, but there’s just no push. The combined energy is only 11 to 19, so you’d be floating around more than surfing.

Now, here’s where it gets interesting, but also a bit frustrating. From Friday the 14th right through Sunday the 16th, the swell picks up significantly. Friday morning sees a 7 ft east swell (period 7 seconds, combined energy 453 – moderate) and by Sunday afternoon we’re looking at a solid 8 ft swell from the E with a period stretching out to 10 seconds and a combined energy of 1170, which is getting into strong territory. That’s proper groundswell energy. The catch? The wind is a relentless cross-shore to cross-onshore, blowing 19 to 25 mph. It’s going to be lumpy, messy, and cross-chop central. For a reef, this is going to be a bumpy, washing-machine ride. I’d say this is more of a kite-surfing situation than a clean paddle session. The swell size over 8 ft on Sunday also means this is strictly for experts only, and with those onshore winds, it’s going to be a battle. For a brief window Monday the 17th, the wind swings to a cleaner cross-offshore from the SE, and the swell drops back to a more manageable 4 ft to 5 ft from the ENE (period 9-10 seconds, combined energy 303-332). That’s the standout window – decent, punchy waves with clean faces. But it’s brief, and crowds are possible here, so get on it early.

After that, we drop right back into a flat spell. From Tuesday the 18th all the way through to Monday the 24th of August, it’s tiny to non-existent. Swell heights are mostly below 3 ft, periods are short (5-8 seconds), and combined energy is mostly under 100. The wind is often clean and cross-offshore, but there’s nothing to ride. It’s a long, dry gap of almost a week with no worthwhile surf.

Finally, we get a little bump back on Tuesday the 25th of August, with a 5 ft east swell (6-7 second period, combined energy 206 to 223). It’s moderate, but the wind is a cross-shore again, so it won’t be glassy. It’s better than nothing, but not a standout.

So, to sum it up: the only real standout is Monday the 17th for a short clean window of chest-to-head-high waves. The weekend of the 14th to 16th has the size, but the wind kills it. The rest is a long wait for something worth paddling for.

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.
