The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s shaping up for The Reef at Culebra. Straight up, I gotta be honest with you – this outlook is a tough one. The whole 16-day window is looking pretty flat and uninspiring, with every single session flagged as "poor surf conditions." We’re looking at a real dry spell, so if you’re itching to get wet, you might need to manage your expectations.

The trouble starts right from the get-go. For the first week, from Friday the 4th all the way through to Thursday the 11th, we’ve got tiny, weak swell. The combined wave energy is mostly in the double digits, like 62 or 93, which is real weak. The swell direction is all over the place from the east and northeast, but the size is barely a ripple – mostly 1ft to 3ft. The wind is a constant cross-off from the ESE, which would usually be a good thing, but with waves this small, you’re just battling a moderate to fresh breeze for nothing. The water temp is about average for this time of year, so no surprises there.

There is a bit of a blip on Wednesday the 9th in the afternoon, where the swell jumps to 5ft from the east, and the combined energy hits 218 (moderate energy). But the period is a short, weak 6 seconds, and the wind goes cross-shore, making it a lumpy, cross-chop mess. For a reef break like The Reef, that short period, onshore-angled wind is just not going to produce anything ridable. It's a hard pass.

Then we slide into the second week, from the 12th to the 19th, and it’s more of the same. The swell drops back to tiny 0.7ft to 3ft, with energy mostly in the weak double digits. The wind stays gusty, often up to 19 mph from the east or ESE. The only other small spike is on Friday the 18th afternoon, with 4ft from the east, a 7-second period, and energy at 159 (moderate). But again, the wind is lumpy and cross-shore, so it’s a no-go for a decent surf.

The Reef (Culebra) is a very consistent spot, exposed to the north, and with an optimum swell from the north. But the whole forecast is delivering east and northeast swell at tiny sizes, with the wrong wind angles. There’s just no standout period here, not even a glimmer of a clean, rideable wave. For a reef break, you need a clean swell and light winds, and we’re getting neither. Honestly, this setup looks far more interesting for kite surfing than paddle surfing, with that consistent cross-off wind if you’re into that.

So, plain and simple: there are no good surf options in this 16-day window. The Reef is gonna be flat and bumpy. That’s the way it goes sometimes. The good news is, forecasts can change, and it doesn’t tend to stay this poor for long around here. Keep an eye on it.

Rusty.

A general guide to surfing at The Reef (Culebra) can be found by selecting the local surf guide option on the grey menu.

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.
