The Lowdown

Alright folks, Rusty here. Let's be straight with you. The surf outlook for The Reef (Culebra) over the next couple of weeks is, to put it bluntly, pretty damn poor. We're looking at a long stretch of small, weak, and messy conditions. There's no way around it.

We kick things off on Monday, September 7th, and the surf is tiny. We're talking ankle-biters at 2.3ft, with a weak energy reading of 83. The wind is a cross-off from the ESE at 16 mph, which is about the only positive, keeping the surface reasonably clean. But there's just no power behind any of it.

From Tuesday, September 8th, right through to Friday, September 11th, it's a real grind. Swell drops to a dribble of 1.3ft to 1.6ft. The energy readings are pitiful, mostly in the 30s and 60s, with a brief uptick to 64 on Tuesday afternoon. It's all short-period, wind-slop with periods of 7 to 12 seconds and no real punch. Winds stay in the 19-22 mph range, mostly cross-off or cross, so it's small and a little tricky.

Now, heading into the weekend, we see a tiny pulse on Saturday, September 12th. The swell bumps up to 3.6ft, and the energy climbs to a more moderate 130. It's still short-period at 7 seconds, and the wind is a cross-shore, making for some lumpy conditions. It’s the biggest surf of the window, but calling it 'the best' is a stretch. Sunday, September 13th, sees a similar story with 3ft and energy back down to 112.

The rest of the second week is pretty much a write-off. From Monday, September 14th, we see the swell fade back down to nothing. We’re looking at 0.7ft to 1.3ft for the most part, with weak energy figures in the teens, 20s, and 30s. There's a brief moment on Wednesday morning, September 16th, with a longer 14-second period, but it's only 0.7ft of swell, so it won't even break. The wind does go light and cross-off at times, which keeps things glassy, but you'd need a log just to catch a ripple.

The reality is, for The Reef (Culebra), a good swell from the N is what would light this place up. We're getting scraps from the E and ENE, which won't wrap in properly. It's not a good look. This is a very consistent break, so it tends not to stay this bad for long, so keep an eye on the charts. But for now, you're better off finding something else to do.

This setup, with the small, weak surf, does mean that the water is warm, at 85.1°F and that's about normal for this time of year.

Alright, that's all from me. Hang tight, keep the faith, and maybe wax up the longboard just in case. Later.

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.
