The Lowdown
Alright crew, Rusty here. Let’s break it down.
The first week and a half for The Reef (Culebra) is pretty much a no-go. We’re looking at a long wait until something decent shows up in the second week.
From Wednesday the 12th through Monday the 24th of August, it’s mostly flat with poor conditions. You’re looking at tiny waves, often under 1ft, with fresh winds blowing 20 to 25 mph. The combined swell energy is weak, mostly in the single digits or low teens (12, 11, 9). There’s a pulse of bigger surf around Friday the 14th and Saturday the 15th, with 5ft to 6ft waves from the east, but the period is short (7 seconds) and the wind is a messy cross-shore. The energy spikes (406, 357, 331), but the conditions are poor. That’s a kite-surfing window, not a paddle-surfing one.
Then we hit a bad stretch. From the 17th to the 23rd, it’s tiny again. Clean conditions on some mornings, but the swell is barely a ripple — 0.3ft to 0.6ft. The energy is pathetic (10, 4, 2). A long gap of nothing.
Here’s the standout. Tuesday the 25th afternoon starts to show some life. A 6ft swell from the ENE, with a moderate 6-second period, but the wind goes light and cross-off. The energy climbs to 245. It’s still marginal, but it’s a sign.
The real winner is Wednesday the 26th of August. Both morning and afternoon are looking clean with offshore breezes. The morning has a 5ft swell from the ENE with a nice 10-second period, and the energy is a solid 473. The afternoon bumps up to 6ft from the east (9-second period) and a beefy 652 energy. The wind is offshore and clean. This is the best on offer. The Reef is exposed to the north, and this ENE swell is a good match. The water temp is about average for the season. It’s a long-range call, so don’t book the time off yet, but this is the one to watch.
A 5ft to 6ft wave is a bit much for groms, but for the intermediates, with that clean, offshore wind, The Reef could be firing.
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.
