Table - best surf conditions forecast for The Reef (Culebra) over the next 16 days.
Right, g’day, I’m Rusty. And I’ll be honest with you, it’s a pretty grim run of it for The Reef (Culebra) over the next 16 days. The forecast is a flat spell with barely a ripple worth paddling for. The first session that might get you wet isn’t until Sunday morning, July 12th, and even then, it’s a struggle. The rest of the outlook is a long stretch of small, weak, and messy conditions.
The whole window is dominated by easterly wind, blowing at 15 to 18 mph, which is a cross-shore or cross-off for the reef. That’s not ideal for a spot that needs that northerly optimum swell direction. The water temperature is about average for this time of year, so no need to stress about a wetsuit.
Let’s start with Sunday the 12th. The morning shows a 4 ft swell from the east, but with a period of only 5 seconds and combined energy of just 98 (weak), it’s a junky, short-period windswell. The wind is fresh and cross-shore, making for a lumpy cross-chop. It’s not surfable. Sunday afternoon is even weaker, with 3 ft and 54 energy. Monday the 13th morning is the only slight glimmer, with a clean 4 ft east swell and 102 energy (still moderate), and it’s a cross-offshore breeze. It’s the best you’ll see, but it’s still poor. The rest of the week is a dead zone: from Monday afternoon through to Friday the 17th, the swell drops to 0.7 ft, with periods under 10 seconds, and energy levels in the single digits. It’s flat.
Saturday the 18th sees a bit of a pulse, with a 4 ft east swell and 119 energy (moderate), but with a period of only 6 seconds and a fresh cross-shore wind, it’s a lumpy mess again. Then it’s back to flat until Sunday the 19th afternoon, when a 4 ft east swell arrives with 145 energy (moderate), but the period is still a short 7 seconds, and the wind is cross-shore. It’s not worth the drive.
The next week, starting Monday July 20th, the energy picks up a bit – 5 ft east swell with 239 energy (moderate) – but it’s still a short-period windswell (7 seconds) with moderate cross-shore breeze. It’s poor. Tuesday the 21st has a similar story with 3 ft east swell and 128 energy. The standout for the whole forecast is actually the cleanest conditions on the 22nd and 23rd, with a cross-offshore breeze, but the swell is tiny – 2 ft and 1 ft respectively. You’d be on a longboard, and only if you’re desperate.
The final weekend, July 26th and 27th, offers a 4 ft east swell with period of 6 seconds and 136-141 energy (moderate), but it’s a lumpy, cross-shore affair. The poor surf conditions are flagged for every single record. There’s nothing here for a beginner – the occasional 5 ft swell is manageable, but the quality is so bad it’s not worth it. For an expert, there’s nothing to get excited about. The reef is inconsistent and rarely breaks when it’s this small. Honestly, this setup looks more interesting for kite surfing than paddle surfing, given the constant wind and short-period chop.
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.
