The Lowdown
G'day, Rusty here. Look, I'm gonna level with you—this next 16 days is a tough stretch for the region. The Reef (Culebra) is about the only game in town, and she's a reef break that's very consistent, exposed to the north, and works best with swell from the north. The water temp is sitting at 85°, which is about 1° warmer than the long-term average, so it's pretty much what you'd expect for this time of year.
Right now, from Sunday the 23rd through to the end of August, it's a flat, frustrating mess. We're looking at tiny swell heights around 0.7 ft to 1.0 ft, with weak energy readings (6 to 18) and short periods around 6 to 8 seconds. The wind is a solid cross-shore from the east at 16 to 19 mph, which just adds to the chop. It's a write-off.
We get a little bump on Wednesday the 26th with swell pushing 3 ft from the ENE, and the combined energy jumps into the moderate range (121 to 131), but the period is still short at 8 seconds and the cross-shore wind keeps it messy. Thursday the 27th sees a long-period groundswell of 13 seconds, but the swell is only 2 ft from the NE, so the energy is moderate (177 to 145) but the waves are gutless. The pattern stays poor right through to the end of August. There's a solid gap of no real surf until the very end of the month.
Then, on Monday the 31st of August, things finally get a bit interesting. The morning brings a 4 ft swell from the ENE with a 13-second period, and the combined energy jumps to 524—strong energy. The wind turns cross-offshore from the east at 12 mph, which makes for clean conditions. The afternoon sees the swell nudge up to 5 ft from the same direction, with a 12-second period and energy at 613 (strong). Still, the wind is a gentle cross-shore from the east at 9 mph, creating a slight cross-chop. This is the best stretch in the entire outlook. A 4 ft to 5 ft groundswell with that long period is going to wrap nicely into The Reef, and with that offshore wind, it'll be clean. It's a standout window, but it's a Monday and Tuesday, so you might have to play hooky. The swell direction is ENE, which is a bit off the optimum north, but it'll still work. I'd be eyeing the Monday morning session.
The rest of the first week of September is a return to small, weak surf. Tuesday the 1st starts with a 4 ft swell from the ENE at 10 seconds and moderate energy (296), but it drops off quickly. The rest of the week is all 1 ft to 2 ft, with periods of 6 to 11 seconds and energy readings that are weak to moderate at best. The wind is mostly cross-offshore from the ESE at 12 to 19 mph, keeping it clean, but there's just no power.
The second week of September is quiet. Saturday the 6th sees a pulse of 6 ft from the east at 6 seconds, with moderate energy (241), but with a short period and cross-shore wind, it's going to be lumpy and messy. That's more of a kite-surfing day than a paddling one. After that, it's back to tiny, weak waves through to the 7th.
So, the call is simple: you've got a long, flat stretch until Monday the 31st of August. If you can get out Monday morning at The Reef, you'll be rewarded with a solid 4 ft groundswell, long period, and clean conditions. After that, the window closes fast. The rest is a waiting game. Keep an eye on the forecasts, but for now, sharpen your sticks and be ready for that Monday window.
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.
