The Lowdown
Alright folks, Rusty here with a look at what’s on the cards for the next couple of weeks.
We’ve got one spot on the radar: Matanzas. It’s a reef break, exposed to the swell, so it grabs a lot of what’s out there. The water is sitting at 55°, which is about what you’d expect for this time of year – nothing out of the ordinary.
The first real shout comes on Thursday the 23rd with a morning session. The swell is a clean 5 ft coming from the WNW with a light cross-off breeze. It’s not huge, but the energy is moderate (378) and it’s clean. Thursday afternoon, however, gets a lot bigger and messier. Swell jumps to 8 ft from the W with a period of 12 seconds, but the wind swings onshore and it gets choppy. That one’s for the experts only, if anyone.
Friday the 24th morning is where we start talking. 7 ft of W swell at 11 seconds, with a light cross-off wind. The combined energy is solid (1071), and the report calls it excellent for experienced surfers. That’s a proper stand-out morning. The afternoon drops back a bit but stays rideable.
Saturday the 25th morning is a real treat. It’s smaller at 4 ft from the W, but the wind is glassy – dead calm. That means mirror-clean surface. The energy is still moderate (527). It’s not a beast, but for a fun, clean session on a reef, that’s hard to beat.
Sunday the 26th morning is interesting. The swell is tiny at 2 ft, but the period is a very long 18 seconds from the WSW. That’s proper groundswell energy, and it’s clean with a cross-off breeze. Combined energy is still moderate (703), which is surprising for such a small face. This will be a long-period, clean, mellow wave – perfect for a longboard on a reef or point. It might close out on a beach, but on a reef it'll be lined up.
Monday the 27th is a big one, but there’s a catch. We’ve got 10 ft of W swell with a 13-second period coming in. The combined energy is strong (3267). This is big, powerful stuff. But the winds are cross-shore, creating some chop. This is expert territory only, and the quality is marginal due to the wind. It's heavy, but not perfect.
The following week settles down. Monday the 3rd of August afternoon is a hidden gem. 6 ft of W swell at 11 seconds, and the wind goes glassy again. Combined energy is moderate (1014), and it’s calling it excellent for experienced surfers. That’s a top pick.
Tuesday the 4th of August morning sees a 8 ft swell from the WSW, but it’s a touch onshore. Still, for the bold, there’s wave energy there (1413).
After that, the Thursday the 7th of August morning looks like another big push: 8 ft from the W at 12 seconds, with strong energy (2169). But it’s cross-shore and bumpy, so again, only for the brave.
For the best of the best, I’m looking at Friday the 24th morning for that solid, clean, experienced surf, and the hidden gem on Monday the 3rd of August afternoon for glassy perfection. The Saturday 25th morning is your classic fun, clean, smaller session.
Remember, after the first week the long-range stuff is promising but we’ll see how it holds.
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.
