The Lowdown

Alright folks, Rusty here. Let’s take a good look at what’s cookin’ for The Reef in Culebra over the next 16 days.

To be straight with ya, it’s a bit of a flat spell for the most part. The entire outlook is just one long stretch of small, weak surf. The first half of the forecast, from Monday the 17th of August right through to the start of the following week, has nothing worth paddling out for. We’re looking at waves mostly under 3 ft, with a short, weak period. The combined swell energy rarely tops 100 (101 to 104 at best), and the wind is mostly cross or cross-onshore, messing up the surface. You’ll see some cleaner conditions from Thursday the 20th onwards with cross-offshore winds, but the swell just isn’t there to back it up. There’s a noticeable gap here with no real surf on offer for over a week.

Now, the one standout – and I mean the *only* one to get your hopes up – is a pulse that arrives on Tuesday the 25th of August. This is the big one for the period. We get a jump in swell energy, hitting a combined energy of 1118 in the morning. That’s a serious number. The swell comes from the NE at 7 ft, which is decent size, and the period is 10 seconds – solid. The swell direction is from the north-east, which is the optimum for The Reef.

But here’s the kicker. That day is a real mixed bag. The wind on Tuesday morning is cross-on from the NE at 22 mph, and it gets worse in the afternoon, turning into a strong 25 mph cross-on breeze that’ll blow it out. The water temp is probably around average for the time of year, no big anomalies stick out. The surf on Tuesday will be big, but messy and lumpy. This isn't beginner territory with waves over 5 ft; it’s more for the experienced crew who can handle a bit of chop and some strong wind. It’s a short window, and the crowd there can show up sometimes, so be ready to share the peak.

After Tuesday the 25th, it drops right back off. Wednesday the 26th sees cleaner conditions with some cross-offshore wind, but the swell fades fast to under 3 ft. From Thursday the 27th onward, we’re back to tiny waves and minimal energy (12 or less in the combined energy). The rest of the run into early September is largely flat or close to it.

So, the long and short of it: if you’re keen, your best – and really only – bet is the morning of Tuesday the 25th of August. It’ll be a lumpy, windy, and pushy session, but the energy will be there. For the rest of the 16 days, leave the board at home.

Stay safe out there.

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.
