The Lowdown
Alright, Rusty here, and I gotta be straight with you – the outlook for The Reef (Culebra) over the next 16 days is a tough one. We've got a long stretch of flat, blown-out, or just plain messy conditions. The water's sitting about average for this time of year, so no surprises there.
The first real chance of anything worth paddling for comes on Wednesday, August 6th, with a small bump. But even then, it's mediocre. The best of a bad bunch looks like Saturday, August 2nd, in the morning. We'll see a tiny 1.0 ft of swell pushing in from the ENE, with a period of 8 seconds. The wind is a cross-offshore breeze out of the ESE at 16 mph, which will keep the surface clean. The energy is weak, at just 89, so it'll be small and weak. It's a reef break, so it needs a bit of push to get going, and this is barely enough. It's not a standout, just the least-worst option.
After that, there's a massive gap. From Sunday, August 3rd, through to the end of the forecast window, we're looking at flat to tiny waves, with the combined energy barely cracking 20 most days. The wind is either onshore or cross-shore and is often fresh, making it lumpy. The best we get is a few afternoons where the swell tries to show up on August 6th and 8th, but it's always accompanied by a cross-shore breeze that kills the quality. There's a moment on Monday afternoon, August 10th, where the wind turns a bit more cross-off, but the swell is still a weak 4 ft from the east with a short 6-second period and only 129 energy. It's just not good.
Honestly, for the entire 16 days, there's not a single session I'd call a standout. The moment the swell gets over 3 ft, the wind is usually howling, or it's a short period windswell. The Reef is a great spot when it's on, but it's not on. It's a real bummer, but sometimes the ocean just shuts down. Forecasts can change, but for now, I'd leave the boards in the car and maybe take a walk.
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.
