The Lowdown
Alright, folks, Rusty here. Let’s break down what’s on the menu for Matanzas.
To be honest, the first week is a bit of a slog. From Tuesday afternoon, September 1st, all the way through the end of the following week, it’s mostly onshore and cross-shore winds making a mess of things. There’s wave energy in the water – the combined energy numbers are moderate to strong (439 to 1293) – but the wind is just ruining the shape. You’ll see a lot of “poor surf conditions” in the data. Not a lot of reason to paddle out.
The one real standout, the only time I’d say “drop everything and go,” is the morning of Sunday, September 6th. The wind goes glassy – dead calm, just 5 km/h from the WSW. That’s a gem. The swell is a solid 5ft from the SW with a long 15-second period, bringing real groundswell energy. The combined energy is strong (1071). It’s labeled as “excellent surf conditions for experienced surfers.” That’s your window.
After that, Monday the 7th still has some size (5ft to 5ft) but the wind goes cross-on, making it choppy. Tuesday the 8th and the rest of the week just drop back into messy, poor conditions. The swell sticks around but the quality is gone.
Looking further out, around the 11th and 12th of September, the swell kicks up – 6ft to 8ft from the SW – but the wind is screaming at 25-35 km/h from the S or SSW. That’s a cross-shore gale. At that size and with those winds, Matanzas is going to be a washing machine. It’s honestly more of a kite-surfing setup than a paddling one. The 8ft on Saturday, September 12th is only for experts, and even then, the wind will make it ugly.
For the rest of the 16-day window, it’s a lot of waiting. The 13th through the 16th have some energy but the wind never lets up. There’s a chance on the morning of the 16th with lighter winds (10 km/h) but the swell is only 3ft and the period is dropping off. The water temp is about 56°F, which is pretty normal for this time of year, so no surprise there.
So, bottom line: your best bet, and really the only clear standout, is the morning of Sunday, September 6th. Mark it. Everything else is a fight with the wind.

Information about the Matanzas Surf forecast
The above surf forecast table for Matanzas provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Matanzas can be found by selecting the local surf guide option on the grey menu. Our Matanzas 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 (Matanzas) 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 Matanzas 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.
Matanzas is 47 km (29 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.
