The Lowdown

Hey, Rusty here. Taking a look at The Reef in Culebra, and I gotta say, the next 16 days don’t offer anything to get excited about. It’s a long, flat spell ahead.

We start on Friday the 11th, and it’s a dud. Swell is just 1ft from the NNE with a weak, short 8-second period. The combined energy is a measly 24, and there’s a moderate cross-breeze blowing at 16 mph. Water temp is 30°, pretty average for the time of year. That’s the only decent thing I can say.

From Saturday the 12th through the morning of Friday the 18th, it stays flat to ankle-biters. Swell heights bounce from 0.3ft up to 4ft, with periods mostly under 10 seconds. The wind stays cross or cross-off, but the chop is lumpy, and the energy numbers are in the gutter, usually below 100. A few sessions on the 16th and 17th clean up with cross-off winds, but with swell barely a ripple (0.3ft – 0.7ft), it’s just a clean, flat lake. The 4ft wave on Friday the 18th morning pushes the energy to 121, but the period is a weak 6 seconds, so it’ll be junky.

The last week, from around the 19th to the 26th of September, stays stubbornly small. Swell hangs around 1ft to 2ft, with some longer period pulses hitting 11 seconds on the 26th afternoon (energy up to 133), but the waves are still poor and the wind keeps a cross element. There’s no window where it all comes together.

Honestly, for the full 16 days, this looks way more fun for a kite than a surfboard, with the consistent side winds and weak, short-period swell. Keep the board waxed and wait for the next system. Forecasts can change.

Rusty.

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.
