The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Culebra over the next couple of weeks.
First up, the only break in the mix is The Reef (Culebra) . It’s a very consistent reef setup that’s exposed to the north, and right now the water temp is sitting at 84°, which is pretty normal for this time of year. No big anomaly, nothing to worry about.
Honestly, the outlook is a grim one. There’s a long stretch of poor conditions ahead. Starting from Friday, August 7th, right through to at least Wednesday, August 12th, the wind is howling out of the east at 15 to 18 mph, blowing straight cross-shore. The swell is small, short-period junk — mostly around 3ft to 5ft from the east-northeast, but with periods of only 5 to 8 seconds. The combined wave energy is weak to moderate (190 down to just 14). Everything is marked as “poor surf conditions” and scores a zero. It’s just messy, choppy, and not worth paddling out.
There’s a little flicker on Thursday, August 13th. The swell bumps up to about 5ft to 6ft from the east (period still only 6-7 seconds), and the wind turns cross-offshore from the east-southeast at 18 to 21 mph. The water cleans up a bit, and the energy climbs to 213 and then 268. Still, with those short periods and the brisk wind, it’s not what I’d call a standout. It’s just the least ugly day in a rough stretch.
Friday, August 14th, brings the biggest swell of the period — 8ft from the east with an 8-second period and strong energy (613 to 695). That sounds promising, but the wind swings back to a full cross-shore at 21 mph. At that size, with that chop, it’s going to be a lumpy, bumpy mess. This is serious, expert-only territory, and even then, the wind will tear it up.
From Saturday, August 15th, through Monday, August 17th, we see waves between 5ft and 7ft, but the wind stays stubbornly cross-shore from the east at 15 to 18 mph. The energy drops off slowly from 496 down to just 10 by Monday afternoon. The period gets a little longer on the 17th (10 seconds), but there’s almost no swell left.
The last few days of the window, from August 18th to the 22nd, are basically a write-off. Tiny waves, mostly below 2ft, with some afternoon thunderstorms possible. The wind sometimes goes cross-offshore, which cleans it up, but there’s no swell to ride. The energy values are in the single digits or low teens.
So, what’s the best on offer? Honestly, if you’re desperate, Thursday, August 13th, is the most rideable day, with clean-ish conditions and some waist-to-chest-high swell. But it’s not a classic. For bigger-wave hunters, Friday, August 14th, has the size, but the wind will make it a battle. Neither is a true standout — it’s just a rough run for Culebra. If you’re a kiter, that Friday might be more your speed, because the paddle-in conditions look pretty average.
Stay patient. Forecasts can change.
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.
