Alright folks, Rusty here with a look at what's shaping up for Matanzas over the next couple of weeks.

Alright, first thing’s first: Matanzas is looking at a solid run of waves kicking off Friday morning, July 3rd. The water’s sitting at 53°F, which is a bit colder than normal for this time of year – so don’t forget the booties if you’re not used to it.

Friday morning, July 3rd, is where we start. We’ve got a clean 3ft swell from the southwest, with a nice 13-second period and the wind is dead glass. It’s not the biggest, but it's clean and the energy is moderate (419). A good way to ease into the weekend.

Saturday, July 4th, the morning looks a little messy with a cross-shore wind, but the swell is still a clean 3ft from the SW, and the period gets up to a very long 19 seconds. That long period is a real treat; it’ll wrap in nicely at this reef setup, but those set gaps will be longer. The afternoon picks up to 5ft and the wind cleans right up to a cross-offshore, offering some quality rides.

But the real standout, the one you don’t want to miss, is Sunday morning, July 5th. The swell bumps up to a solid 7ft from the SW, with a long 16-second period. The wind is light and cross-offshore. The combined energy is powerful (2125). This is excellent for experienced surfers – it’s a bit too big for beginners. That’s your best session of the early run.

Monday morning, July 6th, holds well with a 6ft southwest swell and clean, light cross-offshore winds. The energy is still strong (1325). Tuesday morning, July 7th, drops to 4ft but remains clean and glassy from the cross-offshore wind. It's a nice recovery day.

Then the next real standout appears on Wednesday morning, July 8th. The swell jumps back to 7ft from the WSW, and the wind is glassy. The energy is pumping (2085). This one’s for the experienced again, with the caveat that the period is a little shorter at 14 seconds, but the power is undeniable. Thursday morning, July 9th, is also a gem with a 5ft SW swell and glassy conditions.

We hit a rough patch from Friday, July 10th, through Saturday, July 11th, with strong winds and poor quality. That’s about two days of no good surf. Then we get some tricky, mixed-up conditions until another round of big, powerful swell shows up on Monday morning, July 13th. The swell hits 12ft from the WSW with very strong energy (4020). That’s big. It's marginal for everyone but experts, and the cross-shore wind keeps it from being perfect.

Another big pulse is expected on Saturday afternoon, July 18th, with a 10ft WSW swell and a very long 15-second period, but it's carrying heavy rain and cross-onshore winds. The energy is massive (4458), making it look more like a session for the kite crew than paddle surfers, though a handful of experts might find a ledge.

So if you’re picking your windows, Sunday morning the 5th and Wednesday morning the 8th are your absolute standouts in the first week. For the second week, the Monday the 13th is the biggest but it’s wild.

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.
