The Lowdown
Alright folks, Rusty here. Let’s be straight with you – the next 16 days look like a write-off for decent waves at The Reef in Culebra. There isn't a single standout or even a so-so session hiding in this forecast. The break is a reef setup that really needs clean, north-directed swell and light easterlies or offshore south winds to work its magic. What we’ve got instead is persistent medium-to-strong east and east-southeast winds blowing cross or cross-off, with a short-period, weak swell coming in from the east and northeast. That’s not what this spot wants to see.
Water temp is sitting around 84°, about average for this time of year – but you won’t be spending much time in the water anyway.
Looking at the run in order: Thursday the 30th of July through Sunday the 9th of August, we see swell heights bouncing between 1ft and 5ft, but never with any real energy. The combined energy readings are mostly weak, often under 200 and sometimes dipping below 100 for days (258 on Thursday morning, then dropping to 62 by Sunday afternoon). The period is a lousy 5 to 8 seconds – that’s windswell, not groundswell. It’s crumbly, weak, and messy. Even on the rare occasions the wind turns cross-off, the waves are too small and weak to bother with.
From Monday the 3rd of August right through to Thursday the 6th, the swell basically flatlines. Energy readings hit zero or just a couple dozen at best – 0, 0, 27, 15, 13, 59 – all tiny and poor. That’s several days in a row where it’s barely worth looking at the ocean.
Things tease a little around Thursday the 6th afternoon, where the combined energy climbs back to 112, but the swell direction is northeast at only 3ft and 8 seconds – still weak and not right for The Reef. Then from Friday the 7th onward, it’s more of the same lumpy, cross-shore chop with east winds blowing 15 to 28 mph. By Wednesday the 12th and Thursday the 13th, winds are a strong 25–28 mph, the swell is tiny again (0.7ft to 1.0ft), and the whole thing is just messy.
Bottom line? There’s nothing here. The Reef (Culebra) is not going to offer a single worthwhile session in this entire 16-day stretch. When the forecast is this blank and the winds stay wrong, it’s not surprising for this area – but it’s still a bummer. If you’re keen to get wet, you’d be better off checking if any protected spots with cleaner wind are holding, because out here it’s a no-go.
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.
