The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this outlook for The Reef (Culebra) is a tough one. We’re looking at a long, dry spell with very little to get excited about over the next 16 days.
Right now, and for the first week, it’s a total write-off. We’ve got a strong, persistent cross-shore wind hammering the reef, creating lumpy, chopped-out conditions that are just not surfable. The swell is mostly small, weak, and coming from the wrong direction for this spot. The combined wave energy is weak to moderate, but the wind just kills any chance of a clean wave. You’re looking at a gap of over a week with no real recommendations.
The only flicker of hope comes around Tuesday, August 18th. We finally see a shift to a light offshore wind from the SSE, with the swell coming in from the ENE at 3 ft. The period is a solid 9 seconds, giving it a bit more shape. The combined energy is moderate, and the offshore wind will clean things right up. This is your best bet in the whole run. It’s not huge, but it’s the one session that looks genuinely surfable and fun. The Reef (Culebra) is a very consistent spot, so it’s a bit of a shock to see such a blank run, but the forecasts can change. Keep an eye on that Tuesday.
After that, the winds turn cross-shore again and the swell drops right off into tiny, weak waves for the rest of the period. Not much else to say on this one.
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.
