The Lowdown

Alright folks, it's Rusty here. Let's get real about the stretch ahead down at The Reef in Culebra. This is a classic exposed north-facing reef setup, so it picks up whatever's coming. Overall, the next 16 days are looking pretty flat and frustrating, with barely a pulse of proper swell.

Right now and through the first few days, the water temp is sitting at 84°, right about normal for this time of year, so at least a warm paddle when there's something to paddle for.

Let's start with this Thursday morning, August 13th. The swell is tiny, just 0.7 ft from the NNE with a short 9-second period. The combined energy is weak at (11). We've got a strong breeze from ESE making it cross-off, which keeps the surface clean, but honestly, there's nothing to ride. The afternoon doesn't get any better, with a 0.3 ft, 13-second period swell—so long and weak that it's nearly dead flat.

Friday the 14th brings a bump up to 6 ft from the east, but the period crashes to 7 seconds. That's a short, weak windswell. The combined energy climbs to moderate (344), but a fresh cross-breeze from the east makes it lumpy and cross-chop. It's messy. Not great.

Saturday the 15th looks similar: 6 ft from the east, 7-second period, moderate energy (382), but again that fresh cross-wind is ruining any chance of clean waves.

Sunday the 16th is where things get a bit more serious, but not in a good way for paddling. We're seeing 8 ft from the east with a 7-second period. That's a lot of short-period power—combined energy hits a strong (643). But with a strong cross-breeze and a risk of t-storms, it's going to be a messy, chaotic mess. This is more of a kite-surfing setup than a surf session for most of us.

From Monday the 17th, the bottom drops out again. Tiny 1 ft to 2 ft swells with weak energy (46-48) and cross-off winds that clean things up, but with no size. This flat spell drags on for several days. Tuesday the 18th, Wednesday the 19th, and Thursday the 20th all show less than 3 ft of swell with periods of 5 to 8 seconds. The energy stays weak to moderate (9 to 85), but it's cross-shore chop most of the time.

The second week looks even more lackluster. From the 21st through the 28th, swells are small, mostly under 3 ft, with very weak combined energy figures, often under 100. Winds are a mix of cross-off and cross, with lots of t-storm risks. There's a quick spike on August 24th afternoon with 5 ft from the east and 8-second period, giving moderate energy (262), but it's cross-shore and lumpy again.

There is nothing that stands out as a "go now" moment. The highest quality on paper might be the 8 ft on the 16th, but with strong cross-wind, poor quality, and a beach/reef setup, it's more for the wind junkies than us. For pure surf, this forecast is a dud.

Keep an eye on the charts, but for now, this stretch is a right-off. It won't stay this way forever—forecasts change—but the next 16 days are a write-off for The Reef.

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.
