The Lowdown

Alright, Rusty here. Let’s talk about what’s coming up in the next couple of weeks.

We’re looking at a pretty quiet stretch overall. The only break worth mentioning is The Reef (Culebra), a reef setup that’s very consistent—but this run is mostly about waiting for the right moment. The water temperature is about 85°, which is pretty normal for this time of year.

The real standout is Sunday afternoon, August 30th. That’s your window. We’ve got a 7 ft swell from the ENE with a 10-second period, and the energy reading (808) is solid. The wind swings offshore from the south, and that’s going to make the waves glassy and clean. Expect very good surf conditions at The Reef, and the swell direction is exactly what this spot likes. Crowds are sometimes around, so be ready for company.

After that, it’s a long dry spell. From Monday morning, August 31st, all the way through Saturday, September 5th, there’s nearly no swell—most of the time heights are under 2 ft, with energy readings in the single or low double digits. Winds are mostly cross-off or cross, but with nothing to ride, it’s a dead zone for about six days.

Things nudge back up around Sunday, September 6th, with a 4 ft ENE swell and offshore winds again in the afternoon. Energy reading is 264—moderate—so it’s a possible session, but it’s not as strong as the August 30th window. The following days stay small and messy.

Around September 14th, we see a 5 ft east pulse, but the period is only 6 seconds—short and weak. The energy is moderate (211), but the surf conditions are poor, so it’s probably not going to be worth the paddle.

If you’re a beginner, the 6 ft to 7 ft on the best days may be a bit heavy. For experts, that 7 ft Sunday is the clear call.

Bottom line: the 30th of August afternoon is the one to aim for. The rest of the 16 days is mostly flat or marginal. Forecasts can change, so keep checking back.

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.
