The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the table for the next couple of weeks.
Right off the bat, I gotta be straight with you – the outlook for this stretch is pretty grim. We’ve got a long, frustrating gap of flat, messy, or just plain poor conditions stretching from now all the way through the first week of September. There’s no real surf to get excited about for over a week. The first faint glimmer of anything surfable doesn’t show up until Sunday, the 6th of September, and even then, it’s barely worth mentioning.
Let’s break it down. From Thursday the 27th of August right through to Saturday the 5th of September, it’s all "poor surf conditions" across the board. The swell is tiny, mostly under 3 ft, coming in from the NE or E with short, weak periods. The wind is a constant problem – cross-shore and breezy, with a nasty cross-chop ruining what little shape there is. The combined energy is pathetic, barely cracking triple digits on a good day, and often sitting in the weak 25-60 range. It’s a write-off.
Finally, on Sunday the 6th of September afternoon, we get a tiny pulse. The combined energy creeps up to 101 (moderate energy), with a 2 ft swell from the ENE at 9 seconds. The wind goes light and cross-off, so the surface will be clean. But let’s be real – that’s ankle-to-knee high at best. The file calls it "surfable waves but very ordinary conditions," and that’s being kind. You’d be scratching for a ride on a log.
Monday the 7th of September actually offers a glimmer of hope for the dawn patrol. The morning shows a light offshore wind from the S, with 1 ft from the NNE, period 10 seconds. Clean conditions. The afternoon is similar, with a moderate offshore. The scores are still a 1 out of 10, but that offshore wind is a major positive for clean faces. Still, 1 ft is tiny.
That’s pretty much it. After that, we’re back to tiny, weak swell and cross-shore wind for the rest of the second week right through to Friday the 11th of September. Nothing else stands out.
Look, this is a tough run. For a spot like The Reef (Culebra) that’s "very consistent", it’s a real surprise to see such a blank spell. But sometimes the ocean just shuts off. The wind is the main enemy here, and with the swell direction coming from the NE and E, it’s never matching that optimal N direction at this break. The water temp is a balmy 85°, which is about average for this time of year, so at least the paddle won’t be cold.
If you’re desperate for a paddle, Sunday the 6th afternoon or Monday the 7th morning might give you a clean but tiny window. Otherwise, I’d save the energy. This is a stretch where the setup looks more interesting for a kite than a surfboard, to be honest. Keep an eye on the charts – it tends not to stay this poor for long.
Rusty.

Information about the The Reef (Culebra) Surf forecast
The above surf forecast table for The Reef (Culebra) provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at The Reef (Culebra) can be found by selecting the local surf guide option on the grey menu. Our The Reef (Culebra) surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (The Reef (Culebra)) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
