Table - best surf conditions forecast for The Reef (Culebra) over the next 16 days.
Alright folks, Rusty here. Let’s be real about this Culebra stretch. The Reef (Culebra) is a solid, very consistent spot, but for the next couple of weeks, the conditions are going to be a real battle. This isn't a total loss, but you’ll need to be picky.
We start on Friday, July 10th, with a 5-foot easterly swell that’s got a short, weak period. The real issue is that fresh 30 km/h cross-shore wind from the east, just chopping everything up. The wave energy is moderate at best, but with that cross-chop, it’s going to be lumpy and messy. The water’s a warm 84°, which is standard for this time of year. This same pattern of fresh cross-winds and poor surf sticks with us through the weekend and into next week. Saturday and Sunday bring similar-sized swell, but the period drops to a pathetic 5 seconds, and the energy falls off a cliff.
Monday morning, July 13th, gives us a brief moment of relief. The wind turns cross-offshore, cleaning up the surface, even though the swell is still small and weak at just over 4 feet. It’s the cleanest we’ve seen, but not a classic.
Then it’s game over for a while. From Monday afternoon through to Thursday, July 23rd, the swell just dies. We get over a week of tiny, flat waves—mostly under 2 feet. The combined energy drops to single digits. There are clean, glassy mornings in there, but there’s absolutely nothing to ride. A long, boring gap.
Things try to pick up again around Saturday, July 18th. A pulse of easterly swell rolls back in at 4 to 5 feet, with moderate energy. But that darn wind is back as a fresh cross-shore, so it’s going to be lumpy again. This bumpy, 3-to-5-foot pattern continues through the next week. Thursday the 23rd shows some promise in the afternoon with cross-offshore winds and a solid 5-foot swell, but the wind still messes it up later in the day.
Looking to the end of the run, Friday the 24th and Saturday the 25th hold size around 5 feet from the east, but the wind stays moderate to fresh and cross-shore. More cross-chop.
Honestly, the one and only window that stands out in this whole forecast is the afternoon of Thursday, July 23rd. You get a 5-foot east swell with clean, cross-offshore wind. That’s your best shot at a fun, decent session. Everything else is either flat or blown out. This reef can handle power, but Mother Nature just isn’t playing ball this time.
Keep your eyes on the wind, and don’t expect any magic.
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.

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.
