The Lowdown
Righto, let's get stuck into what's happening at Matanzas. The water’s sitting at 56°, which is pretty much bang on average for this time of year, so don't expect any surprises there.
The first real window of opportunity kicks off on Sunday afternoon the 2nd of August. We've got a solid 10ft swell rolling in from the west with a 12-second period, packing a serious punch with combined energy of 2380. That's a lot of power in the water. The wind is light and offshore, so the reef is going to be filtering that energy into some proper, clean lines. This is big, powerful surf though – definitely for experienced surfers only. This is the standout of the whole run, no question.
Monday the 3rd is your next great call. The morning starts with a 7ft west swell, a light cross-offshore breeze, and it’s clean. The afternoon session is where it gets dreamy: a glassy, offshore wind from the WNW, with that same 7ft west swell. The combined energy is still strong at 1452. The waves will be a bit more manageable size-wise, but the conditions will be near-perfect. That’s the best two days on offer.
It gets a bit messy from Tuesday the 4th through to the end of the first week. The wind swings onshore or cross-shore, and the swell quality drops into marginal territory. There’s still some decent wave energy around, like 1530 on Wednesday morning, but the cross-onshore breeze will put a chop on it. Not worth chasing.
Saturday the 8th of August shows a bit of a tease. The morning has a 6ft southwest swell and a clean offshore breeze from the ESE, with moderate energy (1167). It’s clean, but the swell is a bit smaller and weaker than the start of the period.
The second week is a bit of a mixed bag. There’s a big pulse of swell on Sunday the 9th of August, with 10ft from the southwest and a huge combined energy of 3190, but it’s blowing a moderate to fresh cross-shore wind, so it’s going to be lumpy and messy. That’s a lot of raw power, but it's not going to be pretty. The following days drop off in size and energy, mostly staying in the marginal range with cross-shore winds. The standouts in the second week are the mornings of the 10th and 11th of August, with a light breeze and 7ft and 5ft southwest swells respectively, but the wind is cross-shore, not offshore, so it’s not the same quality as the first few days.
The last few days of the run, from the 14th to the 17th of August, see a drop in energy and a lot of onshore wind. There’s a late pulse on the 16th of August with 8ft southwest swell and a strong 2837 combined energy, but the wind is onshore and choppy. The 17th of August also has an 8ft swell, but it’s cross-onshore. Not the way you want to end the run.
So, bottom line: the first two days, Sunday the 2nd and Monday the 3rd of August, are the ones. Big, clean, powerful swell. After that, you’re waiting for a clean-up that’s not really coming.

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.
