The Lowdown

Alright, boys and girls, Rusty here runnin' the numbers on our only real wave for the next couple weeks: Matanzas. Water's about normal temp for the season, so no worries on that front.

Let's kick it off. Sunday the 2nd is a beast. We're talkin' a solid 10 ft swell out of the west, just raw power (2474 combined energy). Wind's a cross-off, so it's rideable but not clean. By afternoon it settles a little. That's expert territory – 10 ft plus on a reef is no joke.

The absolute gem of the whole run is Monday morning, the 3rd. Swell drops to 7 ft from the west, still a long 12-second period, and the wind goes dead flat, glassy. Picture that. The wave energy is still huge (1445). If you're solid on your backhand, this is the session. The afternoon gets a cross-onshore bump, but that morning is as good as it gets.

Then the wind goes to crap Tuesday through Wednesday. The swell hangs around 7 ft down to 5 ft from the west-southwest, but it's all cross-chop. Still a ton of energy (between 1011 and 1310), just rough.

We hit a real ugly stretch from Thursday the 6th through to Monday the 11th. Winds howling at 28 mph on Thursday morning, making a mess of the waves. There are a couple of cleaner windows on the 10th but the surf's still marginal.

The surf turns back on for the intermediates Wednesday the 12th. Swell drops to 4 ft from the southwest, and the wind goes glassy again in the afternoon. The call is "expect very good surf conditions." The energy is moderate (542). Thursday the 13th morning stays clean with a tiny 2 ft but a long 16-second period – on that reef, it'll produce a fun little wave.

The last few days, from the 15th to the 17th, a new west-southwest swell pushes in, getting back up to 6 ft by Monday the 17th with a 14-second period. Morning winds are light, so it should be okay, but it's borderline lumpy.

The Pick of the Litter: For the biggest, cleanest power, you gotta be on Monday morning, August 3rd, at Matanzas. Don't be late. For a small, glassy, loner session that still has some pull, hit Wednesday afternoon the 12th or Thursday morning the 13th. Everything else is a battle with the wind.

Rusty, out.

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.
