The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for Matanzas over the next couple of weeks. It's a bit of a mixed bag to start, but there's some real promise further down the line.
The water's sitting at 54°, which is a bit colder than normal for this time of year, so you'll want a decent steamer.
Here's the deal: the next few days are pretty cooked thanks to strong northerly winds and messy conditions. Don't even bother paddling out Wednesday or Thursday – Thursday morning has a tiny 2ft swell but it's howling a near gale from the NNE, absolute rubbish. Friday's no better with strong breezes ruining any chance of clean waves. Saturday morning offers a little hope with a 4ft WNW swell and cleaner conditions from a moderate NNE breeze, but it's only marginal. We're looking at a gap of a few days with nothing worth recommending.
Now, Sunday the 19th is where things start to turn. That morning we've got a clean-looking 5ft WNW swell with an offshore Easterly light breeze. Smooth as, with moderate wave energy (678) and a good 12-second period groundswell. The afternoon stays clean with a 5ft W swell and a gentle NNE cross-off. Solid Sunday session for intermediates.
After that, the work week gets messy again with storms and strong winds, so you're better off waiting.
The real standout is Wednesday, July 22nd. Look at this: a clean 6ft W swell, light NNE breeze, gentle cross-off wind, and solid wave energy (1058). This one's excellent for experienced surfers, but at just over 6ft it's still manageable for strong intermediates if you're feeling brave. Thursday the 23rd morning is also a ripper: clean 8ft WSW swell, offshore ENE light breeze, and a huge energy reading of 1691. That's big, powerful surf – experts only territory. You'll want a reef-friendly setup as that WSW groundswell will be wrapping in nicely.
The following weekend holds some clean but smaller options. Sunday the 26th morning is glassy with a 5ft W swell – perfect conditions for a long session. Monday the 27th morning is also glassy with a 6ft W swell and nothing but calm winds. Both of these are prime windows for a fun, clean paddle. Tuesday the 28th stays glassy but drops off to 4ft.
Looking way ahead to Wednesday the 30th, we've got a massive 10ft W swell with a 13-second period. Energy readings are through the roof (2628 and 3267) but the cross-shore wind and chop will make it a messy, heavy beast. This one's for the hardcore crew only.
So, to wrap it up: your best bets are Sunday the 19th for a clean, fun session, but the absolute pick of the forecast is Wednesday the 22nd morning for quality, powerful waves, or Thursday the 23rd morning if you're chasing XL conditions. The glassy mornings on the 26th and 27th are also worth marking on the calendar.
Stay safe out there.
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.
