The Lowdown
Alright, grab your board, let’s talk about what’s coming. The main spot is Matanzas, a reef break that’s very consistent and open to the swell. Water temp is about 55°F, which is dead average for this time of year.
First real surf is Friday morning, July 24th. We’ve got a 7ft swell from the west, 11-second period, with a moderate energy reading (1071). The wind is light cross-offshore from the southeast at 3 mph, so it’s clean. This is for experienced surfers only. The afternoon drops to 6ft, wind goes cross-on, and it’s more marginal.
Saturday morning, the 25th, is smaller at 4ft, but the wind is light and cross. Not great. But Saturday afternoon, the wind goes glassy, and we get a 3ft swell from the west-southwest with a very long period of 15 seconds. That’s a groundswell, and for a reef, that’s smooth, lined-up waves. Small but clean.
Sunday morning, the 26th, is 2ft with a cross-offshore wind and an 18-second period—very long, low energy (753). The afternoon gets a bit choppy.
Monday the 27th brings a big push. Morning is messy with a 6ft west swell, but the afternoon is 8ft from the west at 14 seconds, with strong energy (2572). The wind is a moderate cross-shore, so it’s lumpy. This is for experts only.
Tuesday the 28th has 7ft and 6ft swells, but with cross-onshore winds, it’s choppy.
Wednesday the 29th morning is a sleeper: 4ft from the west at 12 seconds, with a light cross-offshore wind. Clean.
The big standout is Saturday, August 1st. That morning, we’ve got an 8ft west swell at 12 seconds, with a light cross-offshore wind. The energy is strong (1944). That afternoon, the wind goes glassy, the swell drops to 7ft, but the period stays at 12 seconds. This is the best combination of size and glassy conditions in the whole forecast. For experienced surfers, this is the one.
Sunday the 2nd is blown out with strong winds, but Monday the 3rd morning has a clean 6ft west swell at 11 seconds.
The last good one is Saturday, August 8th afternoon: a small 4ft west-southwest swell with glassy conditions. Not a standout, but clean.
The best on offer is Saturday, August 1st at Matanzas, with that 8ft glassy swell. Friday the 24th morning is also a strong runner-up for the clean, solid 7ft surf.

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.
