The Lowdown

Alright folks, Rusty here. Look, I’m gonna level with you – this 16-day window for The Reef (Culebra) is a tough one. We’ve got a whole lot of "poor surf conditions" staring back at us, and the first real chance of anything rideable doesn’t show up until Tuesday, September 1st. That’s a solid week of small, weak, and messy stuff before we even get a whisper of a wave.

The water temperature is sitting at a warm 85°F, which is about average for this time of year, so you won’t need a spring suit. But don’t get too excited about the surf just yet.

From the get-go, Tuesday morning the 25th, we’re looking at a tiny 0.7 ft swell from the ENE with a weak 8-second period. The combined energy is a measly 10. It’s a write-off. This pattern of small, cross-shore, and choppy conditions just keeps rolling through the rest of the week and into the next. The wind stays out of the east, mostly moderate, just keeping everything bumpy and uninviting. The swell does get a little height on Saturday the 29th, hitting 5 ft from the E, but the period is a short 7 seconds and the wind is a fresh 19 mph cross-shore, making it lumpy and ugly. The combined energy jumps to 242, but the quality just isn’t there for a good paddle.

We finally get a clean-up on Tuesday, September 1st. The morning is still a no-go, but the afternoon session shows a "surfable waves but very ordinary conditions" rating. The swell is still only 2 ft from the E, with a better 10-second period, and the wind goes light and cross-off. The energy is a moderate 142. It’s not pumping, but it’s the only window where you’ll actually get a wave without it being a complete battle. The cross-off breeze will keep the faces clean, so for a longboard or a funboard, it’s your best bet of the whole forecast.

The rest of the run into September stays flat and small. The swell never really gets going, and the wind keeps cross or cross-off but with increasing strength. There’s a slight uptick in period on Wednesday, September 9th, with a 1.0 ft swell from the NNE at 13 seconds, but it's so small the energy is just 40. It’s a long-range groundswell, but there’s nothing to it.

So, to sum it up: it’s a long, slow wait. The only standout is the afternoon of Tuesday, September 1st, at The Reef. It’s not a classic, but it’s the only game in town. For the rest, you’re better off checking the wind forecast for a kite session.

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.
