The Lowdown

Alright folks, Rusty here. Let’s take a good hard look at what’s heading our way for the next couple of weeks. I gotta be straight with you—it’s a pretty flat and quiet run ahead for the most part. The swell window is just not open for business, and the trades are going to be a constant pain. Let’s get into it.

The only spot I’ve got to work with is The Reef (Culebra). Straight off the bat, the water is sitting at 85°F which is about average for this time of year, nothing weird there.

We kick off on Saturday the 12th, and honestly, it’s a non-starter. We’ve got a tiny 3 ft swell from the east with a shocking 5-second period, combined energy is a weak 62, and the wind is a solid 16 mph cross-shore from the east. It’s just a mess of lumpy chop with no power. Poor surf conditions is all we get. Sunday and Monday don’t get any better—same story with smaller waves and that cross-shore wind sticking around. The swell drops to 1 ft and the energy numbers are in the 40s and 50s. This is essentially flat.

We roll into mid-week, Tuesday the 15th through Thursday the 17th, and there’s a slight pulse. On Thursday morning the 17th, the energy climbs to 111 (moderate) and we see 4 ft from the east with a 6-second period. The wind shifts to a cross-off from the east at 19 mph, so the surface cleans up a bit. But that period is still far too short to be meaningful. It’s going to be crumbly and weak. The afternoon of the 17th gets windier and lumpier again.

Then from the 18th through the 22nd, it’s back to depressing 0.7 ft to 1 ft swells, mostly clean with cross-off winds but absolutely no size. The energy numbers drop into the teens and twenties. There’s a solid week-long gap here where you’re not going to want to paddle out.

Looking further out into the last week of the month, things perk up just slightly. Around Thursday the 24th, we get a little pulse from the north-northwest with a 1 ft swell and an 11-second period—that’s a cleaner long-period signal. The wind is cross-off from the east-southeast, so conditions are clean. Energy is 51, but it’s just not enough wave height to get excited about. Friday the 25th holds similar 2 ft from the north, but the period drops to 9 seconds and the wind goes back to cross-shore.

The best of a bad bunch might be Saturday the 26th. We get 3 ft from the north-northeast, a 9-second period, and combined energy of 108 (moderate). The wind is a 16 mph cross-shore, so it’ll be a bit bumpy, but there’s at least a bit of push there. Still, it’s tiny.

Bottom line: this is a long, flat stretch. The prevailing east winds and lack of any decent groundswell mean The Reef is just not on. Kite surfers might get more out of the steady breeze than we will. For the rest of us, it’s a waiting game. Forecasts can change, but right now, don’t hold your breath.

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.
