The Lowdown

Alright, this is Rusty, and I’m looking at the forecast for the Culebra area. I gotta be straight with you – it’s a tough stretch ahead. The only break that has any real data to work with is The Reef (Culebra), and for the first two weeks of this 16-day window, the surf is just not cooperating. The winds are howling out of the east and southeast at 15 to 22 mph, mostly cross or cross-offshore, which is keeping the ocean all chopped up and lumpy. The waves are small, disorganized, and the water is just a mess. It’s a long, bleak run of poor surf conditions from now until the 22nd of September. The water temp is sitting at 85°, which is about 2° warmer than usual for this time of year, so the water is lovely, but the waves are not.

Now, there is a faint glimmer of hope right at the very end. On the 23rd of September, we finally see a shift. The wind eases to a gentle breeze from the east, and the swell starts to show some character. It’s a 3 ft north swell with a 10-second period, and the combined energy builds to 199 (moderate wave energy). The real standout is the afternoon of the 23rd, with a light cross-offshore breeze from the southeast, making conditions clean. The wave comment says "surfable waves but very ordinary conditions" – but for this area in this forecast, that’s a win. The following morning, the 24th of September, is actually the best of the lot. We’ve got a 3 ft north-northeast swell with a 9-second period, but the wind is light and offshore from the south-southeast. That’s glassy, clean, and perfect for a reef break like The Reef. It’s an intermediate spot, very consistent, but it can get crowded sometimes. The north swell direction is a good match for the optimum swell direction from the north. The combined energy is 125 (moderate wave energy). This is the one to aim for. The paddle out will be easier with the light wind and the longer period between sets.

For the rest of the time, if you’re desperate, you could consider the morning of the 23rd, but the cross-shore wind will still be creating a bit of chop. Honestly, for the first two weeks, it’s more of a kite-surfing setup with those strong, consistent winds, than a paddle-surfing one.

Rusty.

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.
