The Lowdown

Alright, Rusty here. Let’s talk about what’s shaping up for The Reef in Culebra.

Right off the bat, I gotta be straight with you – this 16-day window is a quiet one, a real flat spell. You’re looking at a long stretch of nothing much to get excited about. The first solid sniff of surf doesn’t really show up until around the 10th of September, and even then, it’s not a barnstormer.

For the first week or so, from Wednesday the 2nd right through to the 9th, we’ve got tiny, poor-quality surf. Swell heights are mostly below 2 ft, with short periods. The wind is a cross-offshore most of the time, which keeps things clean, but there’s just no push. The wave energy is weak, often in the teens or 20s (like 36 on the 2nd). It’s basically a paddling pool, not a surf spot. If you’ve got a longboard and a whole lot of patience, maybe, but honestly, it’s a real struggle.

Now, the one day that pokes its head up a bit is Thursday the 10th of September. The morning shows a pulse of swell: 5 ft from the east, with a short period of 7 seconds. The combined energy jumps to a moderate 398, which is the highest we see. The wind is cross-off from the ESE at 19 mi/h, keeping it clean. That’s the pick of the entire outlook. It’s right on the edge of being too big for beginners, but for an intermediate surfer, it’s the only session that looks worthwhile. The water temp is a warm 85°, which is about average for this time of year, so no surprises there.

After that little blip, it fades again. The morning of the 12th has a bit of 2 ft east-northeast swell with moderate energy (106), but the wind goes cross-shore, so it’ll be lumpy. The rest of the second week is a replay of the first: tiny surf, clean but weak, with wave energy dropping back into the 30s and 40s. By the 17th, we’re down to 0.3 ft. That’s it.

So, the standout is Thursday the 10th morning. Get it if you can. For everything else, leave the board at home or find something else to do.

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.
