The Lowdown
Alright, Rusty here again. Let's not sugarcoat it: the next sixteen days for our little slice of Culebra are a total flat spell. I'm looking at The Reef, and from Friday the 11th all the way through to Saturday the 26th of September, it's just one "poor surf conditions" report after another.
We're talking about a real drought of surf energy. The combined swell energy barely gets a pulse, maxing out at 91 (weak energy) for a hot minute, but mostly it's stuck in the teens and twenties. The wind is a persistent problem, too – almost always a fresh cross-shore breeze from the East, chopping up what little bump there is. Even when we get a cross-offshore from the ESE, the swell is tiny.
The only break in the game is The Reef, a spot that really wants a clean North swell, but that's just not coming through with any sort of power. The water sits at a warm 85°, which is right where it should be for this time of year.
Honestly, with the wind howling and the surf this small, this setup looks way more interesting for kite surfing than trying to paddle out on a log. It's a long, dry run, and for a place like this, that's just the way the cookie crumbles sometimes. Fingers crossed the models get it wrong, but for now? Don't bother.
Rusty.

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.
