The Lowdown
Alright, I’ve taken a good look at what’s coming our way for The Reef in Culebra over the next couple of weeks, and I’ve got to be straight with you—it’s looking pretty grim. We’re staring down a long, quiet stretch with hardly anything worth paddling out for.
Water temps are sitting at a warm 84°F with the anomaly less than a degree off, so it’s pretty average for this time of year. Not that it’ll matter much, because we’ve got a real dry spell on our hands.
Right out of the gate, Tuesday the 11th is a write-off. We’ve got a risk of thunderstorms, a fresh cross-shore wind howling at 19 mph, and lumpy, cross-chop conditions on a short-period 4 ft swell from the ENE. The combined energy is weak (120), and the wave comment says it all—poor surf. Tuesday afternoon is no better, just bigger wind and the same ugly story.
Wednesday the 12th through to Monday the 17th? Nothing but “poor surf conditions” across the board. The swell drops to nearly nothing on Wednesday and Thursday mornings—0.7 ft to 1.0 ft from the NNE with almost no energy in the water. Even when the swell bumps up to 5 ft to 7 ft from Friday through Sunday, the wind stays cross or cross-onshore, keeping it choppy and messy. The energy hits moderate levels (510 on Friday morning), but with a short 8-second period and that fresh breeze, it’s not going to clean up. This whole first week is a bust.
There’s a little glimmer late on Tuesday the 18th, with a marginal score of 1/10. Swell comes up to 4 ft from the east, period stretches to 8 seconds, and the wind drops to a gentle cross-shore breeze. The combined energy is moderate (245), but it’s still a cross-shore with slight cross-chop—barely rideable for an intermediate on a good day. Then from Wednesday the 19th through Sunday the 23rd, it’s back to tiny surf (1.0 ft to 3 ft), weak energy, and poor conditions.
The best we see in the whole 16-day window is on Wednesday the 26th morning and afternoon. That morning we get a clean 3 ft swell from the ENE at 8 seconds, with a light cross-offshore breeze, and the energy hits 140—still weak, but at least it’s clean. The afternoon is slightly better: 4 ft from the east, 9-second period, a moderate cross-offshore breeze, and a marginal score of 1/10. The energy jumps to 302 (moderate), and the clean conditions mean it’s the only time you might actually get a couple of workable waves at The Reef. But even then, it’s far from firing.
Look, The Reef is a consistent spot that’s exposed to north swells, and the optimum direction is from the north, so we’re getting mainly east and ENE swells here—not ideal. The crowds can show up sometimes, but with this forecast, I wouldn’t worry about that. Honestly, with all the cross-shore wind and choppy conditions, this setup looks more interesting for kite surfing than paddle surfing over the next week and a half.
So to sum it up: don’t hold your breath. The first real chance for a surf is late on the 18th, and even that’s marginal. The best option is Wednesday the 26th afternoon, but it’s still just a slight improvement in a very flat forecast. Keep your eye on things—forecasts can change—but right now, it’s a long wait.

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.
