The Lowdown

Alright, this is Rusty, checking in for your local outlook. We’ve only got one spot on the menu for the next 16 days, and to be honest, it’s a tough stretch.

Let’s get real. The only break in the game here is The Reef (Culebra). Water temp is sitting at a warm 84°, which is about average for this time of year, so no surprises there. But don’t let that fool you – the surf picture is pretty grim for a while.

We’re looking at a long dry spell. From now, through the rest of August and into the first days of September, it’s a whole lot of nothing. The swell is tiny, under 2 ft for days on end, with weak, short-period wind chop from the east. The wind is a constant cross or cross-off breeze, mostly in the 12-19 mph range, which keeps things messy and bumpy. It’s poor surf conditions, flat-out.

There’s a bit of a pulse showing up around Wednesday, August 26th. Swell bumps up to 6 ft in the morning and 8 ft in the afternoon from the east, with the combined energy hitting 519 – that’s moderate wave energy, but the period is a short 6-7 seconds. That’s windswell, not groundswell. The wind is still cross, making it a lumpy, crumbly mess. Not worth the paddle.

We finally see something a little more interesting on Monday, August 31st. The morning offers up 3 ft of east swell, period stretching to 11 seconds – that’s groundswell with some real push. The combined energy is 212 (moderate), and the wind is a light cross-off at 9 mph. This is the first window where the wave quality looks clean and surfable, even if the size is modest. It’s marginal, but it’s the closest thing to a highlight in this entire run.

After that, it fades again quickly. The 16-day forecast ends with tiny waves and onshore junk. There’s really no standout session here. If you’re desperate, keep an eye on the morning of August 31st for a few clean, waist-high rollers at The Reef.

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.
