The Lowdown
G’day, Rusty here, and I’ve been looking over the next few weeks at Matanzas. This reef break is set to fire a few times, but it’s not all smooth sailing. We’ve got a couple of absolute standouts if you’re willing to wait for them.
The swell is coming from the west, which is exactly what this spot loves, and the water temp is sitting about average for this time of year, so no surprises there.
We kick off on Thursday, 23 July, with a morning session that’s looking alright. There’s a 4.3ft west swell, period around 9 seconds, and the wind is a light cross-off from the NNE at 9 mph. The water is clean, and the combined energy is moderate (345). It’s surfable, but nothing to get too excited about. The afternoon gets messy though – the swell jumps to 8.2ft, but the wind picks up to 12 mph, and the energy is strong (1938), but the conditions are marginal with the tide.
Friday, 24 July, morning is the first real highlight. We’ve got a 6.6ft west swell with an 11-second period, which gives it a nice groundswell feel. The wind is a light cross-off from the SE at 6 mph, keeping it clean. The combined energy is strong (1054), and it’s excellent for experienced surfers. This is a solid session for the more capable crew. The afternoon goes cross-shore and drops off.
Saturday, 25 July, is a bit of a mixed bag. The morning has a 3.6ft west swell, clean with a light cross-off, but it’s small. The afternoon though, the wind drops to glassy conditions from the NE at 3 mph, and the swell swings to the WSW at 2.6ft with a very long 15-second period. That period is a standout – it’s a proper groundswell, and it’ll wrap beautifully around the reef. The combined energy is moderate (635), but those glassy conditions will make it a dream. It’s a sneaky good session for those who like it clean and mellow.
Sunday, 26 July, is a write-off. Strong winds up to 19 mph, lumpy cross-chop, and tiny swell. Don’t bother.
Monday, 27 July, morning is a beast. We’ve got a 9.8ft west swell, 12-second period, and the wind is barely a whisper from the NNE at 3 mph. The combined energy is very strong (2420), and it’s clean. This is for experts only – 9.8ft is serious, and the reef will be pumping. The afternoon goes cross-onshore, so get in early.
Tuesday, 28 July, is a gem. The morning is glassy with a 5.9ft west swell, 13-second period, and the combined energy is strong (1183). The wind is dead calm from the SE. This is excellent for experienced surfers, and the conditions will be pristine. The afternoon stays glassy with a 5.2ft swell, making it a long, clean session.
Wednesday, 29 July, morning is clean again with a 4.3ft west swell, 12-second period, and a light offshore wind from the ESE at 3 mph. The energy is moderate (552), and it’s a good, fun wave. The afternoon goes cross-onshore and choppy, so lose it.
Thursday, 30 July, through Friday, 31 July, is a rough patch. Strong winds, messy conditions, and small swell. Stay out of the water.
Saturday, 1 August, is a nice little rebound. The morning is glassy with a 3.6ft west swell, 10-second period, and the energy is moderate (326). It’s a small, clean option for a lazy paddle. The afternoon stays clean but small.
Now, here’s where it gets serious. Sunday, 2 August, morning has a 7.9ft WNW swell, 11-second period, and the wind is a gentle cross-off from the NNE at 9 mph. The combined energy is strong (1245), and it’s clean. This is excellent for experienced surfers. The afternoon is a bit mixed, but the morning is a ripper.
But the true standout is Monday, 3 August. The morning serves up a 9.8ft west swell, 14-second period, with a light offshore wind from the east at 9 mph. The combined energy is very strong (3570). This is excellent for experts. And the afternoon? It’s even better – a 11.5ft west swell, 14-second period, with a light cross-off wind from the SSE at 6 mph. The combined energy is exceptional (5371). This is a once-in-a-forecast

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.
