Table - best surf conditions forecast for Matanzas over the next 16 days.
Alright, Rusty here. Let's talk about what's going on at Matanzas. It's been a bit of a mixed bag, with some flat stretches, but there are a couple gems to look out for. The water is running at 53°F, which is a bit colder than normal for this time of year, so don't skip the rubber if you're planning a long session.
The first day that really gets the pulse going is Wednesday morning, the 8th of July. Matanzas is seeing a clean 5ft SW groundswell, and the wind is glassy out of the south. The swell energy is strong at 1663, and the period is a solid 15 seconds, giving those waves some real punch. This reef is exposed to the SW, right in the sweet spot, so expect well-shaped, lined-up sets. The water is a bit chilly, but the conditions are excellent for experienced surfers. This is the one to circle.
Thursday the 9th gets windier and the waves get messier. Friday the 10th cleans back up in the morning with glassy conditions, but the swell is down to just over 4ft and energy drops to 970. It's rideable and fun, but not the standout.
Saturday and Sunday, the 11th and 12th, get blown out. Saturday afternoon sees a 30 km/h cross-wind that turns the ocean into a washing machine. Sunday barely has any size, with 3ft of crumbly stuff. Those days are a pass.
We then hit a dry patch. Monday the 13th is rough. Tuesday the 14th is a big day, but a bit of a double-edged sword. A solid 8ft W swell rolls in with huge energy at 3390 in the morning, but the wind is cross. The afternoon, however, cleans right up with a light NNE cross-off breeze, and the swell holds at 8ft with a 14-second period. This is for experts only – way too big for beginners – but for the brave, it's a heavy, clean session. That afternoon on the 14th is another true standout.
Wednesday the 15th is still decent with a 7ft WSW swell and clean wind, but the juice is lower. It's good, but not as big.
From late on the 16th through the rest of the week, it's ugly. Friday the 17th has 10ft swell but with a near-gale wind that makes it completely unsurfable. Saturday the 18th is still too windy. The next clean window doesn't come until Monday morning, the 20th of July, but the swell is down to a modest 5ft with only 819 energy. It's a nice glassy morning, but nothing to write home about compared to the earlier windows.
By the 21st, the swell is tiny, and from the 22nd onward it's barely a ripple with 1ft to 2ft waves and very weak energy. The forecast closes out flat.
So, to sum it up: Wednesday morning the 8th for clean, head-high waves, and Tuesday afternoon the 14th for big, clean, expert-only surf. Don't sleep on the 8th.
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.
