Alright, this is Rusty. Let’s talk about what’s on the cards for the next couple of weeks.
We’ve got one spot in the game here: Matanzas. It’s a reef break, exposed to the southwest, and the ocean is about 53°F, which is running a bit colder than normal for this time of year, so don’t forget the rubber.
Right off the bat, Sunday the 5th has some appeal. There’s a solid 7ft swell from the southwest, with a long 16-second period, giving it real groundswell punch. The energy reading is a hefty 2125, so there’s plenty of power in the water. You’ve got a light cross-off breeze making things clean, but this is a reef, and with the swell up over 5ft, it’s not one for the beginners. It’s an experienced surfer kind of deal. The wind holds through the morning, but by the afternoon it swings and gets a bit messy, so the morning session is the one.
Moving into Monday the 6th, the swell drops off a notch to 6ft, but that 15-second period still keeps it long and lined up. Morning looks clean again with a light cross-off, and the wave energy is still solid (1212). Afternoon gets a little lumpier, so again, the early bird wins.
Tuesday the 7th is a write-off. The swell drops and the cross-onshore junk kicks in. Small, choppy, not worth paddling for.
Wednesday the 8th, though… this is a real standout. Glassy conditions in the morning, with a 5ft southwest swell and a 15-second period. Wave energy is back up to 1864. The afternoon stays glassy. This is going to be some of the best, cleanest surf of the entire outlook. If you can get out there, this is the day to circle.
Thursday the 9th and Friday the 10th see the swell hanging around but the wind gets a bit fickle. Thursday has some cross-on wind ripples, but Friday the 10th bounces back with glassy conditions again on a 4ft swell. It’s not as big, but it’ll be clean and workable for a good session.
Then we hit a dry spell. From Saturday the 11th right through to Monday the 13th morning, the swell gets small and the winds are cross or cross-on, making for poor to marginal conditions. It’s a few days of slim pickings.
But hold on – Monday the 13th afternoon is when the big show starts to roll in. The swell jumps to 13ft from the west-southwest, with a 16-second period. The combined wave energy is a massive 7113. This is a serious, expert-only groundswell. It’s going to be huge, but the wind is only a gentle cross-shore, so it might have some shape to it. Even so, at this size, you better know what you’re doing on that reef.
That big swell lingers into Tuesday the 14th and Wednesday the 15th, with 10ft sets and plenty of energy, but the winds stay cross or cross-on, bringing some chop. It’ll be powerful but not as clean as you’d want.
The end of the run from Thursday the 17th through to the 19th has some promising windows. Friday the 17th afternoon has a clean cross-off breeze on a small but long-period 3ft swell (17-second period, energy 1034). Saturday the 18th is glassy with waist-high 4ft swell, and Sunday the 19th is glassy again with 5ft swell. Those are sweet, clean sessions to close out the forecast.
Overall, the standout window is Wednesday the 8th for clean, solid surf. Then brace for that massive swell on the 13th and 14th if you’re experienced enough to handle it. Otherwise, the last weekend of the outlook offers some clean, manageable waves.
Stay stoked,
Rusty.

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.
