The Lowdown
Alright folks, Rusty here. Let’s get straight into it. Looking at the 16-day window for our area, I gotta be honest with you – it’s a grim stretch for The Reef in Culebra. The data shows a long, dry spell with no surfable conditions on offer. There’s a gap from the start right through to the end, with every single time slot marked as poor surf. That’s a solid 16 days of nothing to get excited about, so don’t bother waxing up your board just yet.
The first recorded day is the 26th of July, and it’s a mess. Sunday morning has cloudy skies, a cross-shore wind blowing at 16 mph from the east, and a weak 4 ft swell from the east with a short period of 7 seconds. The combined energy is a limp 159, and the water temp is sitting at 84°, which is about 1° warmer than usual – nothing crazy, just a touch above average. The wave comment says it all: “poor surf conditions.” The afternoon doesn’t improve, with the same wind and a slightly smaller 4 ft swell.
Moving into Monday the 27th, there’s a risk of thunderstorms, but the wind shifts to a cross-offshore breeze from the ESE at 12 mph, which at least cleans things up a bit. But the swell drops to 3 ft from the ENE with a period of 8 seconds, and the energy falls to 101. Still, it’s a “poor surf conditions” call. Tuesday the 28th sees the swell shrink further to 2 ft, and by Wednesday the 30th, it’s a tiny 1.0 ft. There’s a bit of a spike on Wednesday afternoon with a 6 ft swell from the east, but the period is a weak 7 seconds, and the energy hits 252. Problem is, the wind is a fresh 19 mph cross-offshore, and the wave comment still says “poor surf conditions.”
Thursday the 30th holds that 6 ft to 5 ft range with moderate energy in the 300s, but the wind turns cross-shore and lumpy. Same story for Friday the 31st: 5 ft swell but a messy 6-second period and fresh cross-shore winds making it choppy. The rest of the first week and into the second week – from August 1st through to the 10th – is a repeat of weak swells, small periods, and cross or cross-offshore winds that never line up right. The swell energy stays mostly in the double digits or low 100s, with a few blips up to 200, but every single entry is flagged as “poor surf conditions.”
There’s no standout day here. The Reef is a reef break that’s very consistent and exposed to the north, but with the swell coming from the east and ENE all window, the direction is off. The optimum swell direction for this spot is from the north, and we’re not getting that. Even the cleanest conditions – like Monday morning with a cross-offshore breeze – can’t save the tiny swell. And with the combined energy never breaking into the strong range, there’s just no power.
If you’re a kite surfer, the wind is steady and strong from the east, but for paddle surfing, this is a total write-off. It’s a blank run, and honestly, for this area, it’s not that unusual when the swell direction is wrong. Forecasts can change, but right now, I’d leave the board at home.
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.
