The Lowdown

Alright, Rusty here, let's chew the fat on what's coming up at Matanzas for the next couple of weeks.

The water's sitting at about 55°F, right where you'd expect for this time of year.

Kicking off this Sunday the 26th, we've got some really nice, clean surf. Waist-to-chest high waves, about 2 to 3 feet, rolling in from the WSW with a long 16 to 18 second period – that’s proper groundswell. A light offshore breeze is keeping the line-up glassy, and the energy reading is moderate at 686, but it’s quality. A good, quiet session to start the week. Monday the 27th picks up to head-high, around 6 feet, but the period drops to 10 seconds and the wind goes cross, so the surface gets a bit bumpy. The energy is up over 1000, so there's some push.

Tuesday the 28th is a straight washout with rainy, onshore conditions and chop.

Here’s a real treat: Wednesday morning the 29th. The wind goes dead calm – glassy as it gets – and we’ve got a clean 4-foot swell from the west with a 12-second period. The energy is solid at 581. That morning session is the pick of the first week. The waves will be clean, smooth, and fun to surf. Get on it.

Thursday and Friday drop off in size and quality, though Friday morning has a spike to 8 feet from the NW with a short 8-second period, so it's a lot of bumpy water (energy 1101) – that's kite-surf territory or for the brave on a big board.

The first weekend of August is a write-off with dirty weather and strong wind (up to 22 mph on Sunday).

Now, looking into the second week. Monday August 4th morning is a monster: a solid 15-foot swell from the WSW with a 14-second period. The energy reading is a massive 7438. That's a huge, powerful groundswell with clean offshore wind. Only for experts, and it’s a major standout for raw size and energy.

Tuesday is still big, around 11 feet, but with onshore wind, so it gets messy. The rest of that week sees a constant diet of head-high to double-overhead waves (6 to 8 feet) but with mixed, often cross-shore winds. It’s consistent, but not pristine.

The absolute gem of the whole forecast is Sunday, August 9th. The morning is calling for a flat calm, glassy ocean, with a 7-foot swell from the SW and a very long 16-second period. The energy is huge at 3145. That's going to produce powerful, lined-up waves on the reef, perfect for the experienced surfer. It’s the best on offer by a long shot, but it’s a good week out, so keep an eye on it.

So, bottoms line: the best near-term is Wednesday the 29th for clean fun waves. The big prize is Sunday August 9th for serious, clean groundswell, if the forecast holds. There's plenty of swell in between, but the wind is a gamble.

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.
