The Lowdown

G’day, Rusty here. Look, I’ll level with you – this 16-day window for The Reef (Culebra) is a tough one. We’ve got a real dry spell on our hands, with no good surf on offer right through. The first recommendation doesn’t even show up, meaning there’s a gap from the start with nothing worth paddling out for. The whole forecast is a long, flat stretch with poor surf conditions scored across the board, so don’t be holding your breath for a decent wave.

From Friday 21 August right through to Saturday 5 September, it’s a write-off. The Reef is very consistent normally, but this run is an exception. The swell energy never gets strong enough – even the highest combined energy reading hits 443 (moderate) on Saturday 29 August morning, but with a 6ft swell from the east at a short 7-second period, it’s a big, crumbly mess. Winds are mostly cross or cross-off from the east-southeast at 16 to 19 mph, which can keep things clean, but the waves just don’t have the shape. The optimum swell direction for this reef is from the north, and we’re getting east or east-northeast almost the whole time – wrong angle, mate. The water temp’s about average for this time of year, so no drama there, but it won’t save the surf.

There are no standout days. Even the bigger pulses – like Saturday 29 August morning with 6ft and 7 seconds, or Friday 4 September morning with 5ft and 6 seconds – are let down by weak, short-period energy that just won’t line up right. The crowded factor’s “sometimes” here, but honestly, there’s nothing to crowd over. If you’re desperate, the cleanest moments are Saturday 29 August morning (cross-off wind, 443 combined energy), but that’s a lot of water moving with no quality to back it up. For the second week, it’s more of the same – shrinking swells down to 0.7ft and long flat spells. A blank run like this is unusual for The Reef, so forecasts might change, but for now, save the wax.

Stay tuned, Rusty.

Information about the The Reef (Culebra) Surf forecast

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.
