The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking at Matanzas for the next couple of weeks.
The first week is a bit of a mixed bag with some fun, clean windows, but the real standout is shaping up for Monday, August 3rd and Tuesday, August 4th. That’s when the ocean really wakes up. The water is currently sitting at 55°F – about average for the time of year, so nothing unusual there.
We start with Saturday morning, July 25th. It’s cloudy, with a glassy 4ft swell from the West, a period of 10 seconds, and combined swell energy of 537. That’s moderate energy, and the conditions are clean. It’s a nice, mellow start.
Sunday, July 26th, looks better. Morning sees a 2ft swell from the WSW with a very long period of 18 seconds – that’s proper groundswell. The wind is a light cross-offshore from the North, keeping it clean. Combined energy is 686. The afternoon holds similar, with a 3ft swell and 16-second period, also clean. A good day for a point or reef.
Monday, July 27th, gets a bit gnarly. The morning jumps to 6ft from the West (10 seconds) with a moderate cross-shore wind, making it choppy. The afternoon sees a solid 10ft swell from the West (14 seconds) with a combined energy of 3017 – strong energy. That’s expert territory, but the cross-shore breeze will mess it up. Not ideal for a paddle.
Tuesday, July 28th, stays big but messy. 8ft and 7ft swells from the West, period around 11 seconds, but with the same moderate cross-shore chop. Combined energy is 1474 and 1019. Not worth the hassle.
Wednesday, July 29th, brings a nice reprieve. Morning has a 4ft swell from the West (12 seconds) with a light cross-offshore breeze from the SSE, making it clean. Combined energy is 504. The afternoon is similar with a 4ft swell. A solid, clean session.
Thursday, July 30th, is glassy. Morning has a 3ft swell from the WSW (12 seconds) with zero wind, combined energy 221. The afternoon is even smaller at 2ft and glassy. Tiny but clean.
Friday, July 31st, the wind picks up. A 4ft swell from the West (13 seconds) but with a 35 km/h cross-offshore wind. Combined energy 690. It’s clean but the wind will be a battle. The afternoon is similar with 5ft and 20 km/h wind.
Saturday, August 1st, stays windy. 5ft and 6ft swells from the West (11 seconds) with moderate cross-offshore winds. Combined energy is 704-778. Clean but not great.
Now for the standout. Sunday, August 2nd, offers a big 12ft swell from the WNW (11 seconds) with a combined energy of 2980, and Monday, August 3rd, is the pick. Monday morning sees a massive 13ft swell from the West (14 seconds) with zero wind – glassy perfection. Combined energy is a huge 5686. This is exceptional, but it’s only for experts. The afternoon is still 13ft but with a slight cross-on breeze. Tuesday, August 4th, is still excellent for experienced surfers, with a 12ft swell from the WSW (13 seconds) and a light cross-offshore breeze, combined energy 3890.
After that, from Wednesday, August 5th, through to Sunday, August 9th, the swell hangs around but the wind turns cross-shore or onshore, making it choppy. The size goes from 7ft down to 5ft, then back up to 10ft, but the wind is messy. The combined energy is still strong, but the quality is poor. The setup looks more interesting for kite surfing than paddle surfing during this period.
So, the clear winner is Monday, August 3rd, morning. If you’re an expert, that’s your window. Tuesday, August 4th, morning is next best. For the rest of us, the clean windows on Saturday 25th, Sunday 26th, and Wednesday 29th are your best bets.
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.
