The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s ahead for The Reef in Culebra, because honestly, it’s a bit of a mixed bag of mostly small, messy, and just plain poor surf conditions stretching out over the next sixteen days. The water temp is sitting about average for this time of year, so nothing wild there.

Right off the bat, we’ve got a rough start. Saturday morning, August 1st, is a no-go with a weak 4ft east swell, but a fresh 19 mph cross-shore wind is just chopping it to bits. The combined energy is only a weak 207... it’s not worth paddling out. That afternoon gets even worse with a shorter period, lumpier mess. Sunday morning, August 2nd, cleans up a little with a cross-offshore breeze, but the swell drops to 4ft from the east, and the energy is still nothing to write home about (133). The rest of that day and into Monday and Tuesday, we’re looking at flat spells and tiny 2ft waves with barely any energy.

Honestly, the first week is a write-off. There’s a gap of several days where the models are showing nothing but tiny, weak, or flat surf. It’s not until the 7th of August (Friday morning) that we see a bump to 5ft from the east, but the energy finally gets into that moderate range at 201. Problem is, it’s still cross-shore and lumpy. The Reef is exposed to the north for optimum swell, and this east windswell is not the direction it likes. The whole first week is a struggle.

Now, the standout moment in this whole 16-day window happens around the 11th and 12th of August. Tuesday morning, August 11th, we get a solid 6ft east swell with a moderate 7-second period and the combined energy jumps to 325 – that’s proper moderate energy. The wind is a clean cross-offshore from the ESE at 22 mph, which is a major positive. This is the best on offer, but it’s still a long way out, so treat it as promising but not locked in. The Reef is a reef break, so it can handle a bit of east swell, and with the clean conditions, it’ll be the pick of the fortnight. The swell stays around 6ft to 6ft through Wednesday, August 12th, with that cross-shore wind picking up again, making it lumpier in the afternoons. The energy is strong (375) but the offshore wind is the key.

After that, we drop back down. The 14th and 15th of August have 5ft east swell with clean cross-offshore winds, but the energy is back to moderate (141-159). It’s surfable but not the standout. The very end of the run, Sunday morning, August 16th, is a total flat with a tiny 0.7ft north pulse and just 6 energy. That’s it, folks.

So, to sum it up: the first week is a dud. The real action, if it holds, is that couple of days in the middle of the second week (August 11th-12th) with The Reef offering up some punchy, clean waves. After that, it’s a slow fade. The Reef is a very consistent spot, but the direction and wind are just not lining up for most of this outlook.

Rusty out.

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.
