The Lowdown
Alright, Rusty here, let’s take a look at what’s cookin’ for Culebra over the next couple of weeks.
Honestly, partner, this stretch is a bit of a heartbreaker. We’ve got a full 16-day window, and there’s not a single recommendation on the table where the conditions line up for a good session. The surf is just flat-out poor throughout the whole period.
The only spot on the menu is The Reef (Culebra), and it’s a super consistent reef break exposed to the north. The water’s sittin’ at 85° right now, which is pretty average for this time of year, no real surprises there.
Right from the get-go on Saturday the 5th, we’re looking at tiny waves around 2ft from the east, with a short period of 8 seconds. The combined swell energy is weak (55), and the cross-off breeze from the ESE will keep the surface clean, but there’s just no power. That same story pretty much holds through the first week – small, weak swells from the east and northeast, never cracking 3ft. The wind stays mostly cross-off or cross, keeping the ocean tidy but useless.
We get a little spike in energy on Wednesday the 9th afternoon, with the swell jumping to 5ft from the east (266 combined energy – moderate) but the period is a scrappy 7 seconds and it’s crossed up with a fresh cross-shore wind, so you’re fighting lumpy chop. That’s more a kite-surfing setup than a paddle-in wave.
The second week is even more grim. From Sunday the 13th onward, we’re seeing swells barely 3ft on the best days, dropping to nearly nothing by the 18th (combined energy of just 7). The wind stays annoying, mostly cross or cross-off, never giving us that true offshore magic.
The only faint glimmer is toward the very end, on Sunday the 20th. We get a 3ft pulse from the north with a 9-second period, and the cross-off breeze from the ESE keeps it tidy. The combined energy climbs to 145 – moderate – so there’s a bit of push. But at that height and with that wind, it’s still a pretty average day, not a standout by any stretch.
Bottom line: there’s no good surf to chase here in the next 16 days. The whole run is a blank. With this spot being super consistent, it’s unusual for it to stay this flat for so long – forecasts can always flip, but for now, keep the board in the bag.
Rusty.

Information about the The Reef (Culebra) Surf forecast
The above surf forecast table for The Reef (Culebra) provides essential information for determining whether the surfing conditions will be good over the next 16 days. 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.
