The Lowdown

Alright, listen up. Let's talk about The Reef (Culebra). I've got to be honest with you, it's been a while since I've seen it this quiet. The water's warm, a balmy 85°F, which is about right for this time of year, so it's all about board shorts.

The first few days are a total washout. We're looking at peaks of around 2 feet with a weak, short-period swell. The wind is okay, mostly cross-offshore, but there's a bit of a bump on it. The energy is weak, only registering 59. It's just not worth the paddle.

On Monday the 7th, there's a hint of a long-period groundswell from the NE, but it's tiny, only 1 feet. The period is a nice 12 seconds, but it's just not enough to get anything going. It's a big tease.

Then things get a little more interesting on Tuesday afternoon, the 8th. The swell starts to push up to 4 feet, and the energy jumps to 181. But, it's a junky easterly swell with a period of only 6 seconds. It's all bump and no push. Wednesday the 9th sees the swell max out at 5 feet with energy at 259, but the wind turns more cross and it gets lumpy. It's not a clean wave at all. This continues into Thursday the 10th, with more 5-foot surf, but it's still that same short-period mess.

You know, for a reef like this, we need a proper long-period swell to make it sing, but we're just getting hammered with this disorganized east windswell. And by the end of the week, it all just gives up.

From Friday the 11th onward, it's a flat-out desert. The swell drops to almost nothing, and the energy falls off a cliff. We're looking at a solid 8-day stretch of tiny, weak waves that won't even break properly. The wind will be up, 18-22 mph, which is going to make it even more of a chore. There's a brief moment on the 17th when the wind drops to a light 9 mph, but with only 1-foot waves, it's a glassy lake, not a surf.

To put it simply: the next week has a few pulses of size but terrible quality, followed by a long stretch of flatness. If you're not a masochist, I'd leave the board in the car. This looks a lot more like a kitesurfing wind farm than a surf break. But hey, the forecast can change, so keep an eye on it.

This is Rusty. Stay salty.

A general guide to surfing at The Reef (Culebra) can be found by selecting the local surf guide option on the grey menu.

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.
