The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the line for us.
The swell is building in for a solid start, with the best of it hitting Friday morning. The water’s sitting at 56°, which is pretty much normal for this time of year, so nothing wild there.
The standout session is Friday morning, August 28, at Cartagena. We’ve got a clean 8ft of WSW swell pushing in with a 14-second period. That’s proper groundswell energy, and with the wind glassy out of the NNW at just 3 mph, it’s going to be smooth as silk out there. The combined swell energy is really pumping at 1966, so there’s plenty of power. This is going to be excellent for experienced surfers – the wave quality is going to be top-notch, but at 8ft, it’s a bit much for the beginners.
Friday afternoon stays at 8ft with a 13-second period, but the wind goes cross-on from the WNW, so it’ll get a bit bumpy. Not the clean pick.
The next decent look is Sunday morning, August 30. Swell drops a touch to 5ft from the WSW, period at 11 seconds, and the wind is glassy again from the NW. It’ll be clean and rideable, with moderate energy (546). A good session for a wider range of surfers.
After Sunday, things get pretty average through the week. We’ve got a run of marginal or poor conditions from Monday, August 31, all the way through to Thursday, September 10. The swell drops off, and the wind is mostly cross or cross-on, so it’s not going to be worth paddling out unless you’re desperate.
There’s a flicker of hope on Friday morning, September 11. The swell bumps back up just a bit to 3ft from the WSW, period at 12 seconds, and we get glassy conditions again from the SW. Combined energy is low (336), so it’s a small clean wave. Good for a longboard if you're keen, but not a standout.
And then Saturday afternoon, September 12, looks similar – 4ft, SW swell, glassy wind from the west. Fun little end to the forecast window, but nothing compared to that Friday morning blast.
So, if you’ve got the skills, Friday morning is the one to circle. Get out there before the wind shifts.
Rusty.

Information about the Cartagena Surf forecast
The above surf forecast table for Cartagena provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cartagena can be found by selecting the local surf guide option on the grey menu. Our Cartagena 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 (Cartagena) 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 Cartagena 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.
Cartagena is 12 km (7 miles) from the city of San Antonio. If you plan a holiday in Santiago, look for hotels and other accommodation in San Antonio. San Antonio has rooms for a wide range of budgets as well as car hire and transport links.
