The Lowdown
G'day, Rusty here, and I’ve got a pretty honest look at what’s coming up for the next couple of weeks. The short story is, we’re in for a rough patch with a lot of average to poor conditions, but there’s one very promising window if you can wait for it.
Right now, the surf is a bit of a mess. The water temperature is sitting at 84°, which is about normal for this time of year, so no surprises there. The first few days are all cross-shore winds and lumpy, choppy conditions. Friday afternoon kicks off with 5 feet of swell from the east at 8 seconds, but the wind is a fresh 22 mph cross-shore, making it messy. The combined swell energy is a weak 265, so there’s not much push either. Definitely not worth paddling out.
Saturday and Sunday don’t get any better. Saturday morning swells up to 8 feet from the east, but with a short 7-second period and strong 25 mph cross-shore winds, it’s just a washing machine. The energy climbs to 588–659, which is moderate, but it’s all chop. Sunday sees a drop back to 6 feet, but still cross-shore, still lumpy. The wind does ease a bit to 19 mph late Sunday, but it’s not enough to fix the mess.
Monday through to the following Monday are all small, weak, and cross-shore. There’s a stretch from the 18th to the 21st of August where the swell drops below 3 feet and the combined energy is under 100, so barely a ripple. The 20th of August offers a small window with a cleaner cross-offshore wind, but the swell is only 2 feet at 8 seconds, so it’s rideable but not exciting.
The real standout is Tuesday, the 25th of August. This is the one to circle on the calendar. The morning looks glassy, with a light SSW breeze at just 3 mph, and 8 feet of east swell at 8 seconds. The energy is a strong 858, and the conditions are expected to be very good. By afternoon, the wind switches to a gentle offshore at 9 mph, keeping it clean, with 8 feet swell. This is a solid, powerful wave, but that 8 feet size means it’s only for experienced surfers—beginners should sit this one out. The Reef (Culebra) is a consistent reef break, so it’ll handle that east swell well, just be aware that crowds are sometimes an issue.
After that, the surf drops off fast. Wednesday the 26th of August is back to tiny, weak swell, and the rest of the week is just small, clean but unrideable stuff. The 27th and 28th have a bit of a longer period (9 seconds), but the swell is only 0.7 feet to 1 feet, so it’s flat.
So, if you’re keen, aim for Tuesday the 25th of August. The rest of the 16 days is mostly a write-off, but that one window is worth the wait.
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.

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.
