The Lowdown
Alright, Rusty here again, but this time in feet and miles. Let’s get stuck into Matanzas.
Starting off, Wednesday and Thursday are a dud – messy, poor conditions with gusty cross-shore winds, not worth paddling out for. Friday the 31st isn’t much better, still cross-onshore and lumpy.
But Saturday the 1st of August, the tide turns. That morning sees a clean 5ft swell from the WSW, with a nice 12-second period and a light cross-offshore wind. Clean conditions, moderate energy (974), and good for intermediate surfers. Crowds can show up, so keep that in mind.
The real highlight is Sunday morning, August 2. That’s your day. An 8ft swell from the west, 11-second period, light offshore breeze from the NE at 9 mph, making for super clean waves. The energy is strong at 1412. This is expert territory – too big for beginners, but perfect for experienced surfers who want to get stuck into a powerful reef break. Best wave of the forecast period, hands down. It can get busy though.
Monday the 3rd still has a clean 6ft dropping through the day, best in the early morning.
Into the second week, Wednesday the 5th brings a huge pulse of very long period groundswell – 16 seconds from the WSW. That’s a massive 10ft at times, with a crazy energy reading of 3570. The wind is cross-shore that afternoon, so not totally perfect, but there will be some freight-train waves coming through. Only for the experienced, and watch the tide.
Water temp is around 55°, dead average for this time of year.
To wrap it up: your absolute best session in this whole 16-day stretch is Sunday morning, August 2 at Matanzas – a powerful, clean, 8ft west swell with light offshore wind. Set your alarm.
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.
