The Lowdown
Alright, Rusty here. Let’s have a look at what we’ve got coming up around The Reef in Culebra.
Right now, and for a solid stretch, it’s pretty grim. We’re looking at a gap of nearly two weeks where the surf just isn’t up to scratch. The wind is mostly from the east at a solid 18 to 25 mph, which is cross or cross-on, turning the surface into a lumpy, choppy mess. The swell is there – between 6 ft and 7 ft from the east – but with short period, poor conditions, and all scores at zero, it’s not worth paddling out. This stays poor right through until about the 25th of August.
There is a flicker of hope right at the end. On Wednesday the 26th of August, things change. The morning shows a 5 ft east swell with a 6-second period. The combined swell energy is moderate at 175. The wind swings to a light breeze from the southeast, going cross-offshore, leaving the surface clean. The surf report actually says “surfable waves but very ordinary conditions” and gives it a score of 1. It’s not a standout by any means, but after two weeks of nothing, it’s the only window.
The Reef itself is a very consistent intermediate reef break, and it’s exposed to the north, which is the optimum direction. The east swell isn’t ideal for it, and the period is short at 6 seconds, so the energy won’t be the best. It’ll be weak and a bit soft. On the plus side, with that light offshore wind, it should be clean if you’re desperate for a splash. The water temperature is about average for this time of year, nothing unusual to note.
For the rest of the month after that, the 27th to the 29th, it drops back into poor territory with cross-shore winds and tiny, weak swell. Not much to write home about.
So, to be honest, it’s a lean period. If you’re a kitesurfer, the windy, messy days from the 14th to the 24th might look more interesting than for a paddle surfer, as the beach-and-reef setup with strong cross-shore wind would give you something to work with. But for a traditional surfer, keep your board on the roof and check the forecast again after the 26th.

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.
