The Lowdown

Alright, Rusty here. Let's have a look at what we've got for this stretch.

To be honest, it’s a pretty quiet outlook. The Reef (Culebra) is a very consistent reef break, but for the entire 16-day window, we’re looking at a long run of poor surf conditions. There’s a significant gap from now through to the end of the period with nothing worth getting excited about. It’s one of those spells where you’re better off leaving the boards in the car.

Looking at the first week, starting from Sunday, September 6th, we’ve got a tiny easterly swell around 3ft with a short period of 8 seconds. Combined swell energy is weak (73). Winds are cross-off from the southeast, so the surface would be clean, but there’s just no push to the waves. That pattern pretty much sets the tone. The water temperature is a warm 85°, which is about average for the time of year, so at least a dip will be comfortable.

Monday through the rest of the week stays tiny, with swell heights mostly between 1ft and 2ft. Periods are all over the place, some long at 12 seconds, but the energy is so weak (mostly under 100) it won't translate into any rideable surf. Winds are mostly cross-off or cross, so the water will look clean, but it's a flat spell.

Into the second week, around September 16th, we see a small bump. The swell picks up to 3ft on the Wednesday morning and afternoon, coming from the east with a period of 5 to 6 seconds. The combined energy is still weak (73 and 64). The wind is cross-shore and fresh, which will make for a lumpy, choppy surface. That’s not the kind of day you paddle out for.

Even though The Reef is a consistent spot, the forecasts are showing nothing but a blank run through to September 21st. It’s one of those periods where the ocean just shuts down for surfers. Keep the wax on the shelf.

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.
