The Lowdown
Alright, Rusty here. Let's have a look at what's on the table for our little corner of the world over the next couple of weeks. I'll be straight with you—it's a bit of a slow burner, so we need to be patient.
We're looking at a long stretch here where the conditions just aren't coming together. From now through the 20th of September, the wind is mostly onshore or cross-onshore, the swell is short period, and it's just messy. There's plenty of energy moving through—moderate stuff in the 200 to 300 range—but it's not translating into anything rideable. You'd be fighting chop and onshore wind the whole time. Honestly, that first real glimmer of hope doesn't show up until the afternoon of Sunday the 20th.
That Sunday arvo, the wind goes glassy and the waves are surfable but ordinary. The swell is only 4 ft from the NE with a 7-second period and combined energy of just 116. It's not a standout by any stretch, but at least you won't be getting blown off your board. For a beginner-friendly spot like Siete Olas, that's about the best we've got in the first week and a half. The water is a warm 84°, which is bang on average for this time of year.
If you're looking for something a little cleaner, the morning of the 22nd offers up another glassy window with similar 4 ft NE swell, but still nothing to write home about. The real shift comes later in the week. On the morning of the 23rd, we get a light cross-offshore wind from the S, and the swell ticks up slightly to 4 ft from the NE with an 8-second period. The combined energy jumps to 200, which is a bit more encouraging, and the comment says clean. That's the first time we can really talk about decent shape.
The 24th morning is glassy again with 4 ft NE swell, but the period drops back to 6 seconds, so it'll be a bit weak and crumbly. Then we hit a bit of a lull from the 25th through the 26th where the swell drops below 3 ft and the energy is weak—down in the 30s and 40s. That's a real quiet patch.
But here's the one that catches my eye: the morning of the 27th. We've got light offshore wind from the SW, the swell is 4 ft from the NE with a 7-second period, and the combined energy is a solid 184. The comment says clean. That's the best looking session of the whole outlook. Offshore wind at Siete Olas, even if the swell isn't huge, will give you clean, workable lines. For a beginner-friendly beach and reef setup like this, that's a winner.
After that, the 28th morning is glassy with 5 ft NE swell and the 29th morning is also glassy with 5 ft NE swell and energy of 264. Both are surfable but ordinary. So overall, we've got a long quiet spell, then a couple of clean windows, with the standout being the morning of the 27th.
Stay patient, keep an eye on the wind, and I'll see you out there when it's clean.
Rusty.

Information about the Siete Olas Surf forecast
The above surf forecast table for Siete Olas provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Siete Olas can be found by selecting the local surf guide option on the grey menu. Our Siete Olas 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 (Siete Olas) 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 Siete Olas 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.
Siete Olas is 8 km (5 miles) from the city of Santa Marta. If you plan a holiday in Caribbean Coast, look for hotels and other accommodation in Santa Marta. Santa Marta has rooms for a wide range of budgets as well as car hire and transport links.
