The Lowdown
Hey, Rusty here again. Let’s run through it in feet and Fahrenheit for you.
Gonna be a rough stretch for Culebra. The Reef (Culebra) is a north-facing reef break, and the next 16 days are looking like a bust. The first surf recommendation is on Thursday, the 30th of July, and it’s not pretty.
We start that morning with some 5ft swell from the east, but it’s short-period, around 7 seconds, with a 30 km/h cross-off wind making it ugly. The combined wave energy is weak (273). Water temp is about normal for the season. This same pattern of poor conditions, lumpy cross-shore winds, and tiny energy hangs around through the end of July and into early August. There’s a big 6-day gap with no real surf to speak of from the 3rd of August until the morning of the 8th. A blank run like this is more normal for the area, but it’s still a bummer.
The only real standout, and it’s relative, pops up on Tuesday afternoon, the 11th of August. We get a 6ft swell from the east, with a strong combined energy of 422. The wind is cross-off from the ESE at 30 km/h, so it’ll be clean. The period is a short 6 seconds though, so don’t expect any power. The next morning, Wednesday the 12th of August, also shows promise. A long-period, 11-second groundswell from the NNW at 2ft, with clean cross-off wind. The energy is moderate (142). That longer period is much better for a reef. Then that afternoon, a bigger 6ft east swell (580 energy) comes in, but it’s short period and lumpy.
So, the only real window is the 11th and 12th of August. If you’re a beginner, that 6ft day on the 11th is going to be too big. Everything else is a washout. The wind is just never going to cooperate for long.
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.
