The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for the Culebra area over the next sixteen days.
Honestly, I've gotta level with you – the outlook is a bit of a tough one. The data we have is only pointing to one spot, The Reef (Culebra), and the whole period is looking pretty grim. There's a long stretch of poor surf ahead, so don't be booking any days off work just yet. The water temp is sitting at 84°, which is about normal for this time of year, so at least you won't be freezing while you're staring at the closeouts.
The first real signs of any swell start on Thursday morning, the 6th of August, with a 3ft NE windswell. But the wind is howling out of the ESE at 16 mph, making it a cross-offshore breeze. The combined energy of all swells directed here is only 101, so it's weak. The rest of that week and into the next is a write-off – the wind is stuck in the east, pumping at 16 to 19 mph, and the swell never gets its act together. The period is short, 6-8 seconds, and the cross-shore wind is just going to chop it up into a mess. It's a solid nine-day stretch of "poor surf conditions" with no real standouts. The swell does bump up a bit around the 14th and 15th of August, hitting 7ft, and the energy picks up to a moderate 388, but the wind is still a strong cross-shore at 22-25 mph. This is looking more like a kite-surfing session than a paddle-surfing one, with that strong breeze and messy cross-chop. For a reef break, that's not the recipe for a good time.
We do see a slight improvement from the 18th of August into the 20th. The swell drops back to 4ft to 5ft, and the wind eases a bit to 12-16 mph. We get a few clean windows with a cross-offshore breeze, but the energy is still weak (145 down to 45). The period is still a short 7-8 seconds, so it's just not going to have the push to make a reef break work properly. The 20th and 21st of August look like the cleanest of a bad lot, but the swell is tiny, only 1ft to 2ft, and the energy is pitiful. There's just no proper surf to get excited about.
To be brutally honest, there's no standout period here. The combination of persistent onshore/cross-shore wind and a short-period, low-energy swell makes The Reef (Culebra) a non-starter for the entire 16-day window. The surf is poor, and the conditions are poor. It's one of those times where the forecast just doesn't have anything good to offer. Fingers crossed it changes, but for now, I'd give this one a miss.
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.
