Table - best surf conditions forecast for Matanzas over the next 16 days.
Alright folks, Rusty here with a look at what the ocean's got cookin' for us. We're focused on one spot for this stretch: Matanzas.
Right out of the gate, Tuesday the 7th is a solid start. We've got a clean 3.6ft SW swell with a 14-second period rolling in. The water's sitting at 53.2°, which feels a touch colder than we'd expect for July, a bit over a degree below the norm, so you'll want that extra layer. With a light S breeze keeping things cross-off, conditions are looking very good. The wave energy is moderate, clocking in at 626, but it's the quality that's got my attention.
The real standout, the one you circle on the calendar, is Wednesday the 8th. Morning brings a glassy 4.9ft SW groundswell with a 15-second period, and that's a recipe for perfection. Combined energy is a strong 1663. This is advanced-level stuff, with that long period making it punchy and best suited for a reef setup like Matanzas. It's going to be clean, powerful, and consistent. Afternoon cleans up again with a cross-off breeze. Top of the list.
Thursday the 9th gets a bit messy, with a cross-on wind from the SSW messing up a 6.9ft SW swell, so that's a day to sit out. The energy is still high at 1818, but it's not worth the chop.
Friday the 10th bounces back nicely. A glassy morning with a clean 3.9ft SW swell, moderate energy at 845, and very good conditions. A great window for a session without the full-on power of Wednesday.
The weekend, the 11th and 12th, looks pretty average with onshore winds and poor surf, so don't get your hopes up. We've got a lull for a couple of days there.
Looking into next week, Monday the 13th brings size back with a 6.2ft WSW swell picking up, but it's got a cross-on wind that spoils the party. A big 9.8ft swell rolls in by the afternoon, but again, marginal conditions.
Tuesday the 14th is the other major highlight in this outlook. We're looking at a solid 7.2ft SW swell with a clean, cross-off breeze. The wave energy is strong at 1668 and the conditions are described as excellent for experienced surfers. This is big, powerful surf for experts only.
After that, the swell drops off through the 15th and 16th, but the glassy morning on the 15th with a 3.3ft SW swell is a nice, easy session if you want a break from the big stuff.
The following week gets interesting again. Friday the 17th has a huge 7.5ft SW groundswell with a 17-second period, combined energy at a massive 2800, but a cross-shore wind adds some chop. Saturday the 18th is a day to rest up.
Then, Sunday the 19th and Monday the 20th are looking like another serious swell window. Both days have a 9.8ft W swell, with clean cross-off winds. The energy is off the charts, 3159 on Sunday. This is big, west swell, likely breaking with a lot of power. The period is a bit shorter at 11-12 seconds, so it'll be a more unruly, powerful beast. Again, this is expert territory only.
After that, the energy fades out through the 21st and 22nd, leaving us with small, sloppy conditions to end the run.
So, to wrap it up: Wednesday the 8th is the top pick for a perfect, powerful session. For the bigger, more demanding days, Tuesday the 14th is a standout, and that last pulse on the 19th and 20th is one to keep an eye on, though that's way out there and a little less certain. Get on it while it's good.

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.
