The Lowdown

Alright folks, Rusty here. Gotta be straight with you – this is a tough one for our local waters. Let’s break it down.

Right now, we’re lookin’ at The Reef (Culebra) and the story is pretty grim for the next couple of weeks. The water temp is sitting at a warm 84°F which is about normal for this time of year, so at least a dip will feel good, but that’s about the only positive.

We kick off on Friday, July 31st, and there’s just nothing happening. The first proper pulse we see is a little bump from the East on Thursday morning, August 6th, with a weak 2ft swell and a period of 8 seconds, but the energy is practically non-existent (40). On top of that, the wind is a cross-shore from the ESE, which will keep it clean but the waves are just too small and weak to get excited about. It’s basically a flat spell.

Then we hit a real dry patch. From Friday, August 7th, all the way through to Monday, August 10th, we’ve got small, messy, weak chop from the East with cross-shore winds. The combined energy hovers around 86 to 137, which is very weak. It’s gonna be lumpy, bumpy, and not worth paddling out for.

The most promising, and honestly the only real standout, shows up on Tuesday, August 11th. The morning session sees a pulse from the East at 5ft with a period of 6 seconds. The combined energy jumps to 249 (moderate wave energy) and the wind goes cross-offshore from the East, which will clean the faces right up. The Reef handles a north swell best, but this East swell will still wrap in. It’s a solid intermediate wave, but with that 5ft size and only a 6-second period, it’ll be a bit short and punchy. If you’re a beginner, that’s pushing your limits. The afternoon stays at 6ft but the wind swings back to a cross-shore, making it lumpy again.

The rest of the 16-day window is a washout. Wednesday, August 12th, and Thursday, August 13th, see similar sizes but the wind is a strong cross-shore (25 mph on Wednesday morning) or a messy cross-off, making it a choppy, blown-out mess. The energy is there (267 on Wednesday morning) but the quality is gone. Honestly, with these strong easterly winds and a beach/reef setup, this looks more interesting for the kite surfers than paddle surfers.

Bottom line: Hold your horses. The only real window is Tuesday morning, August 11th, at The Reef (Culebra) for a clean, punchy session. The rest of the time, you’re staring at a lot of flat, windy, or lumpy water. Forecasts can change, but right now, it’s a patient man’s game.

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.
