The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaking for The Reef (Culebra).
Honestly, I’m looking at the next 16 days and it’s a tough stretch. We’ve got a real dry spell on our hands. The first few days are pretty much a write-off with poor surf and messy, choppy conditions. The wait for anything decent is a long one.
The first real glimpse of hope comes on the morning of the 1st of September. The swell is small, only 2ft from the ENE, but the wind finally switches to a clean cross-off. The combined energy is weak (79), so it’s not going to be much, but it’s surfable. That little window carries into the afternoon, still tiny but clean. After that, we’re back into a long gap of tiny, weak swell and poor surf quality right through to the 8th of September.
The one standout to keep an eye on is the morning of the 9th of September. The swell picks up to 4ft from the North, with a solid 12-second period – that’s some proper groundswell energy. The combined energy jumps to 341 (moderate), which is a big step up. The wind is a cross-shore, not perfect, but it’s a reef break, so a longer period north swell like that can set up some nice lines. It’s about a week and a half away, so treat it as promising but not locked in. The afternoon on the 9th holds similar energy.
Crowds are possible at The Reef, so if you’re keen on that 9th of September morning, get out early. The water temperature is sitting at 85°F which is about average for the time of year.
Overall, it’s a lean run. Hang in there, and watch the forecasts for that 9th.

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.
