The Lowdown
Alright, this is Rusty. Let’s be straight with you – the outlook for The Reef (Culebra) over the next 16 days is pretty grim. We’re looking at a long stretch of poor surf conditions, with the only real size showing up later in the window when the wind is working against us. The water temp is sitting right on 83°, which is bang on average for the time of year, so no surprises there.
The first recommendation doesn’t pop up until the 16th of July, but even then, it’s a no-go. Thursday afternoon sees a tiny 3ft swell from the east with a short, weak 4-second period, and the combined energy is a measly 44 – that’s wimpy. A 16 mph cross-shore breeze is chopping it all up, making it messy. This pattern basically holds for days. The swell direction stays locked in from the east, and the wind is either a cross or cross-offshore, but it’s fresh and strong, keeping the surface lumpy and the waves weak.
There’s a small bump in energy around the 18th and 19th, with swell heights hitting 4ft to 5ft and period climbing to 7 seconds. The combined energy gets into the moderate range (147 to 186), but the wind is still a fresh 19 mph cross-shore, so it’s a windswell washout. The surf quality is still rated poor across the board.
The first real standout in size comes on the 25th of July – Saturday morning. We’re looking at a 5ft east swell, period up to 7 seconds, and the combined energy jumps to 221 (moderate). The wind is a cross-offshore from the east at 19 mph, which will clean the faces up. That’s the best on offer. It’s still a bit of a rough ride with the wind, but for The Reef, this is the window. The afternoon gets a bit bigger at 6ft, but the wind shifts to a cross-shore, so the morning is the call.
The 26th of July keeps the size at 5ft to 5ft, with energy in the 247 to 277 range, but the wind is a mix of cross and cross-off. The morning of the 26th has a risk of thunderstorms and a cross-shore wind, so it’s not as clean.
After the 27th, it drops off fast. Swell heights shrink back to 2ft, the energy plummets, and we’re back to the same old story. The 30th and 31st have a bit of a pulse back to 4ft, but the period is short (5-6 seconds) and the wind is a fresh 19 to 22 mph cross-shore, making it a chop-fest.
So, the honest truth: if you’re desperate, the morning of the 25th of July is your best bet. It’s the only time the swell is decent and the wind is somewhat favourable. For the rest of the 16 days, it’s either too small, too windy, or both. The surf here is a reef setup, so it needs clean conditions, and it’s just not getting them. For a spot that’s very consistent, it’s a frustrating run.
Stay patient, check the forecasts, and maybe have a backup plan.

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.
