The Lowdown

Alright, Rusty here again. Let’s break this down in feet and miles.

We’re in a pretty slow spell for The Reef (Culebra). Over the next 16 days, the surf is really struggling to get going. The first real sniff of a session comes on Wednesday afternoon, the 9th of September, but even then it’s not a slam dunk. The pattern is small, bumpy, and low energy. There’s a dry gap from around the 14th through the 22nd where it’s basically flat or ankle-biters.

The one highlight, the only one I’d bother with, is Wednesday afternoon, the 9th. We get a bump from the east at 5ft, with a short 7-second period. The combined energy is 212 (moderate), so there’s actually some juice. Wind is cross-off from the east at 18 mph, so the surface will be clean. The reef likes the swell from the north best, but east will work. It’s not epic, but it’s the best on offer. Water temp is 30° with a 0.7° anomaly – right around average for the season.

After that, Thursday the 10th and Friday the 11th fade back to 1ft and 1ft, with cross-off winds but almost no energy (30-32). The second week is a total snooze – 0.6ft to 2ft, weak energy, and mostly cross-shore winds. The Reef is a consistent break, so this is a quiet patch. If you’re keen, that Wednesday afternoon is your best bet.

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.
