The Lowdown
Alright, Rusty here. Let’s talk about what’s happening at The Reef in Culebra.
This is a tough one, mate. The whole 16-day stretch is a bit of a write-off for decent surf. Right off the bat, we’ve got a lot of wind that just won’t play nice. The swell is small and short-period for most of it, and the winds are mainly cross or cross-off from the ESE and E, blowing at 12 to 22 mph. That creates lumpy, choppy conditions that just aren’t worth paddling out for. The first real chance of anything comes on Thursday, August 13th, and even that’s a long way off.
The Reef is a very consistent spot, but this run is a rare blank. That happens here sometimes.
For the first week, through to the 12th of August, it's mostly a no-go. We see tiny swells of 1ft to 6ft, but the period is junk, often 6 to 8 seconds, so no power. The combined energy is weak, mostly in the double digits or low triple digits (e.g. 21, 107, 304), which tells you there’s nothing behind it. The water temperature is a very warm 84°, which is about normal for the time of year.
The one bright spot I can see is on Thursday, August 13th. The morning shows a 6ft swell from the E at 7 seconds, but the combined energy jumps to 475, and the wind is a cross-off from the ESE at 25 mph. That’s a strong breeze, but it’s cleaning it up. The afternoon is similar with a combined energy of 541. That’s actually the biggest energy reading in the whole window. This is an exposed reef break, and it prefers swell from the N. This E swell isn’t its optimum direction, but that energy is notable, and the stronger cross-off wind will keep the face reasonably clean. For the confident intermediate surfer, this might be a session. It’s not perfect, but it’s the only time the numbers hint at something worthwhile. Crowds are possible here sometimes.
The rest of the second week, from the 9th to the 12th, fades back into weak, short-period junk again with cross winds, so don’t plan around it.
Bottom line: most of this outlook is a bust. If you’re itching for a paddle, circle Thursday the 13th on your calendar, but keep your expectations tempered.
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.
