The Lowdown
Alright, let me give it to you straight. The Reef (Culebra) is the only spot in the mix for the next 16 days, and it’s looking like a long, quiet stretch. The water temp is about normal for this time of year, nothing to write home about.
We kick off Monday, July 20, with a weak, short-period swell around 4ft from the east, but the period is a puny 6 seconds. The combined energy is only 106 (moderate), and with a cross-shore breeze kicking up a lumpy chop, the waves are just messy and small. That’s the story through Tuesday and Wednesday, with waves staying in the 3ft to 3ft range, same short period, and the wind making a mess of things. Even when the wind turns a little offshore on Wednesday and Thursday, the swell is just too tiny to bother.
By Saturday, July 25, the swell bump up to about 5ft from the east, and the energy climbs to 231 (moderate), but the period is still a weak 7 seconds. The wind is cross-shore and fresh, so it’s lumpy. For a reef, this short-period windswell just doesn’t wrap in cleanly. Not worth the drive.
The following week, from July 27 through August 4, it’s more of the same. There are a few cleaner moments when the wind goes cross-offshore, like on the afternoon of July 31, but the swell is still small and short. The energy never gets strong enough to really make the reef work. There’s a little spike on July 29 and 30 with waves around 5ft from the east, but the period is a miserable 6 seconds, and the wind is cross-shore, so expect lumpy, unorganized lines.
Bottom line, there’s no standout day in this whole 16-day window. The swell is too small, the period is too short, and the wind is too often wrong for this north-facing reef. If you’re really itching to get wet, keep an eye on those cleaner cross-offshore windows, but don’t expect any quality. Forecasts can change, but right now, it’s a big zero for surf.

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.
