The Lowdown

Alright folks, Rusty here. Let’s get into it. We’ve got a pretty quiet stretch ahead for The Reef (Culebra). This is a consistent, exposed reef break that handles north swell best, but over the next 16 days the swell energy is just not there. The water is sitting at 85°F which is about normal for this time of year, so no surprises there.

The forecast starts off flat and messy. From Monday the 31st of August right through the first week of September, it’s all small, weak, and crumbly. Swell heights barely tickle 3 ft with combined energy readings mostly in the double digits – as low as 17 – and the period is short, around 5 to 8 seconds. Winds are cross or cross-off, moderate to fresh, so nothing to get excited about. It’s a long stretch of “poor surf conditions” with scores of 0. That’s nearly a week of nothing worth paddling out for.

You get a tiny flicker on Sunday the 6th of September. The afternoon shows a small 2 ft swell from the east, period at 8 seconds, combined energy at 75 (still weak), but the wind swings to a light offshore from the SSE – that’s a gentle breeze and clean. It’s “surfable but very ordinary,” the best of a bad lot, but still pretty underwhelming. That’s the only highlight in the whole run.

After that, it’s back to the same story. From the 7th through the 15th of September, it’s all tiny waves – 0.3 ft to 2 ft – with cross-off winds, combined energy often in the teens or twenties, and the occasional bit of energy pushing 143 on the 11th of September from a 4 ft easterly with a 6-second period, but that’s short and weak. The quality is still rated poor. The clean conditions are there, but without swell, it’s just a flat, polished lake.

Honestly, for a reef that’s usually reliable, this is a tough run. If you’re desperate, the Sunday afternoon on the 6th is your best shot, but don’t expect much. The rest of the 16 days is a write-off. Bring a towel.

Rusty.

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.
