The Lowdown
Alright, Rusty here. Let’s be straight with you – the outlook for The Reef in Culebra over the next 16 days is a tough one to write.
Honestly, we are staring down a long, flat spell. From this Friday morning, 11th September, all the way through to Saturday the 26th, the swell just isn't showing up. Every day in the records has that dreaded "poor surf conditions" tag, and scores are bottoming out. There is simply nothing rideable on offer. The combined wave energy barely cracks 94 at its best on the 16th, and most days it’s a measly two-digit figure down in the teens. That’s not enough to push a ripple through, let alone a wave.
The wind is mostly cross-off or moderate cross-shore, so the surface will be clean enough, but with swell heights stuck between 0.7 ft and 4 ft and periods all over the place – from a choppy 4 seconds to a long 12 seconds – there is no consistency or power. That long-period 12-second stuff on the 17th and 18th might look interesting, but at only 0.7 ft, it’s just a ghost. For a reef set-up like The Reef, exposed to the north, the swell direction is often from the east or northeast, which isn’t even hitting the optimum north direction that breaks it best. So, nothing is lining up.
There is a gap of flatness right from the start with no recommendations for the entire 16-day period. It’s one of those blanks where you don’t bother checking the cam. This area does have these quiet runs, so don’t be too shocked. Forecasts can always shift, but right now, leave the board in the van.
Rusty.

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.
