Right, folks, Rusty here. Let’s have a look at what’s on the cards for Culebra.
Well, honestly, it’s a tough stretch. The whole 16-day window looks pretty grim for good surf. The issue is that the wind is stubbornly pumping from the east and east-southeast, blowing a fresh 18 to 22 mph nearly every day, which is right across the face of the reef. That cross or cross-off wind is just ruining any chance of clean lines. The few little pulses of swell that show up, mostly from the east, just don't have any quality to them. The first few days are a complete write-off.
The first real movement we see is on Sunday, July 5th, with the swell bumping up to around 4ft, mostly from the east. But that's paired with a fresh cross-shore wind and a scratchy 7-second period, which explains the lumpy, choppy mess. The combined energy is moderate (155), but it’s all just messy.
The same story plays out through the next week. There's a bit more size on Tuesday, July 7th, with 5ft east swell, and the combined energy climbs to a strong 211. But again, the wind is a fresh 22 mph, making it a bumpy, cross-shore mess. It’s the kind of day that looks more interesting for kite surfing than paddle surfing, with that strong onshore flow and a lumpy sea.
For a total of 12 days, from July 4th right through to July 15th, there’s not a single recommendation. The waves are there, but the quality is just absent. The wind finally eases a bit on Saturday, July 18th, dropping to a moderate 15 mph and turning cross-offshore. For the first time, we get a "clean" description, and the swell is a solid 5ft from the east. The combined energy is a strong 240. It’s still not a standout by any means, but it’s the only window where the conditions are even close to surfable. The following morning, Sunday, July 19th, looks similar, with 4ft east swell and clean conditions.
The only real standout, if you can call it that, is that Saturday, July 18th at The Reef. With 5ft east swell, clean conditions from a lighter cross-off breeze, and the reef being very consistent, it’s the best the forecast has to offer. Water temperature is about average for the time of year.
