The Lowdown

Alright, this is Rusty, and I’m looking at the next couple of weeks here around The Reef (Culebra) . Honestly, it’s a bit of a slow burn. We’ve got a long stretch of pretty ordinary conditions before things start to look interesting around the end of the month.

Right out of the gate, from Tuesday the 15th through to the 27th of September, it’s pretty flat and messy. The trade winds are on it pretty hard most days, blowing cross or cross-off at 12 to 18 mph, and knocking any chance of clean surf around. Swell heights are mostly tiny, well under 3 feet, with periods as low as 5 to 8 seconds, so there’s not much push. The combined wave energy is weak, often sitting below 100. The water temp is sitting at a warm 84.9°F, which is about normal for this time of year. That’s a solid 2-week wait for anything worth paddling for.

Then, keep an eye on Sunday the 27th of September. We see a little flicker of life. The morning has light breezes and some cleaner lines, with a 2-foot swell from the NNE (9 sec period), and the energy nudges up to 72 (weak). By the afternoon, a longer period 13 second swell from the NNW rolls in, lifting the combined energy to a more noticeable 176. It’s still not big, but it’s an improvement and clean. It’s a glimmer of hope.

But the real standout, the one you want to circle on the calendar, is Monday the 28th of September. This is the best on offer. Early morning, we get a proper NNW groundswell at 4.6 feet with a 11-second period, light offshore SSE winds at just 6 mph, and the wave energy jumps right up to 569 – that’s a big, powerful reading. That’s legitimate, clean surf. Expect glassy conditions and clean, well-shaped lines. It will be in the intermediate-plus zone, and with those offshore winds, the reef will be handling that swell perfectly. The afternoon holds steady with the same 4.6-foot swell, wind shifting slightly to 9 mph but still offshore and clean.

Tuesday the 29th is still solid, with the swell easing a bit to 3.9 feet from the north, still clean and with good energy (450) under gentle offshore winds. It’s a good follow-up day. From Wednesday the 30th, the signals get a bit more mixed, with the wind picking up and the energy dropping, so the window is really that Monday and Tuesday.

For the ultimate session, get ready for Monday the 28th. It’s a true standout.

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.
