The Lowdown

Alright folks, Rusty here, checkin' in with the local scoop on The Reef. Let’s be straight with you – it’s been a bit of a rough stretch out there, and we’re looking at a long dry spell before anything even starts to whisper about being surfable.

Right off the bat, what we’ve got is a whole lot of nothin’ exciting. The pattern is stubborn: consistent easterly cross-shore winds, mostly moderate to fresh, gustin’ up to 15 or 18 mph. That’s keeping the surface all chopped up and messy. The swell we’re seeing for the first week is small, weak, and confused – mostly short-period windswell from the east, with combined wave energy readings barely cracking triple digits (63, 53, 62 – just sad, weak stuff). So for now, we’re in a holding pattern. This first stretch from Saturday the 22nd all the way through to roughly Sunday the 6th of September is basically a write-off for decent surfing. That’s a solid two-week gap with literally no solid opportunities.

Now, on Saturday the 30th of August, things try to show a pulse in the afternoon. We’ve got swell pushin’ up to 7 ft from the east (8 seconds), and the combined energy jumps to 541 – that’s moderate and the most energy we’ve seen in the whole forecast. But the wind is still a messy cross-shore, so the comment just calls it “marginal.” It’s the only day that even gets a score of 1 out of 10, and that’s telling you everything. For reef breaks like this one (Culebra), that cross-shore chop just ruins the line-up.

The water temp is about average for the time of year, no major anomalies to get excited about – just typical warm tropical bathwater.

As we creep into the first few days of September, the wind does finally ease up. On Tuesday morning the 1st, we get a glassy, dead-calm morning with a slight air from the southwest – beautiful for a paddle, but the swell is puny (2 ft from the NE, 8 seconds). The next day, Wednesday the 2nd, we actually get some clean offshore action from the south, but again, the swell is tiny (0.7 ft, 11 seconds – longer period, but no size). It’s the cleanest, prettiest lineup of the whole outlook, but there’s just no wave to ride.

So, final word: there’s no standout session in this 16-day window. The only one that even slightly deserves a mention is that Saturday the 30th afternoon session with 7 ft, but the wind ruins it. If there’s any hope, it’s that the reef picks up longer-period groundswell well, so if that east pulse cleans up and the wind ever turns offshore, this spot could come alive fast. For now, save the wax for another day.

Stay tuned, forecasts shift. Rusty out.

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.
