The Lowdown

Hey folks, Rusty here. Well, I’ve gotta be straight with you – we’re looking at a pretty bleak 16-day window around Culebra. The Reef is the only break on the cards, and it’s not giving us much to work with. The whole period is a write-off for any decent surf. Honestly, it’s a long stretch of nothing, and it’s going to feel like forever.

We start off on Thursday, September 3rd, with tiny, weak waves. The swell is a pathetic 2ft from the east, with a short, choppy period of just 4 seconds. The combined energy is a measly 27 – that’s barely a ripple. The wind is a cross-off from the ESE at 12 mph, which keeps the surface clean, but there’s no power behind it. The water is sitting at 85°, which is about normal for the time of year, nothing wild there.

This same sad story plays out day after day. Friday and Saturday, the swell barely scrapes up to 3ft, still with a short period, and the energy stays in the doldrums (between 62 and 116). The wind stays a cross-off from the ESE, 12-16 mph, so the surface is clean, but it’s like trying to surf a lake with a light breeze. The waves are just not there.

We get a slight bump in the numbers on Thursday, September 10th, with the swell hitting 4ft from the east, and the combined energy jumps to 249. That’s a bit more push, but it’s still a short-period swell, and the wind is a fresh 19 mph cross-off. It’s still messy and un-rideable in any fun way. The same goes for Sunday, September 13th, when the swell reaches 5ft. That’s the biggest we see, but it’s wind-swell with a period of just 6 seconds, and the wind is coming straight onshore from the east at 16-19 mph, creating a lumpy, churned-up mess. The wave comment says "poor surf conditions" for every single entry, and every single score is a zero. There’s no standout, no hidden gem, nothing to get excited about.

Even the longer-period swell that shows up on Tuesday, September 8th, with a 12-second period, is only 1ft. It’s like a ghost of a swell. With the consistent cross-off wind, it’s clean, but there’s no height to work with.

So, to put it bluntly: don’t bother. The entire 16-day forecast is a bust. There are no gaps in the bad surf; it’s just one long, flat stretch. The Reef is a consistent spot, but it’s not producing. For a place that usually has some pulse, this is a real dud. Sometimes the ocean just shuts down, and this is one of those times. We’ll have to wait and see if the forecasts change, but right now, it’s a no-go.

Stay dry, folks.
Rusty.

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.
