How to Make Agua de Sandía (Watermelon Agua Fresca)
Nothing says summer like some backyard grilling and a big jarra of my homemade agua de sandía. It’s light, refreshing, and made with just three ingredients!

Back in 2013, I had the unique opportunity to travel throughout Mexico and research cooking schools outside of the popular food-lover’s destination known as Oaxaca. It was in the charming city of Morelia, Michoacán that I was able to mix business with pleasure as my mom and younger sister joined me on my culinary investigation. Here, we took a private cooking class with Cynthia Martinez, chef and owner of the adorable San Miguelito restaurant. At the time, she offered cooking classes at her school, Zirita Taller de Experiencias Culinarias, one of the most beautiful cooking schools I’ve been to in Mexico.
It was on this trip that I discovered my sister Ivana’s affinity for agua de sandía (watermelon agua fresca)! Therefore, as a way to always remember our culinary adventure together, I created her favorite drink.
WHAT IS AGUA FRESCA?
Agua fresca literally translates to fresh, cold, or refreshing water, but literal translations do little to describe the true essence of these fruit-forward and fun Mexican drinks. For instance, if I were to call this agua de sandia, “watermelon water,” someone might mistake it for plain water that is infused with sliced watermelon, when it’s so much more than that!
Aguas frescas are non-alcoholic drinks typically made by blending water and sugar with seasonal fruits and vegetables. Some are also made with dry ingredients such as rice, tamarind pods, and hibiscus, which are Mexican pantry staples.
If one day you find yourself in Morelia, I highly recommend that you have a meal at San Miguelito Restaurant! The room with upside-down Saint Anthony figures is like nothing I’ve ever seen. Address: Perif. Paseo de la República s/n, La Loma, 58290 Morelia, Mich., Mexico. Phone: +52 443 354 2195
Now, back to our watermelon agua fresca recipe . . .

INGREDIENTS YOU’LL NEED
All you need to make this delicious Mexican watermelon drink is: fresh watermelon, sweetener of your choice, and water!
STEP-BY-STEP INSTRUCTIONS
1. Blend ingredients
- Working in batches, blend watermelon, sugar, and water on medium setting for 30 seconds.
2. Chill and enjoy
- Chill in the refrigerator or serve over plenty of ice. Garnish with fresh mint or basil leaves, if desired.
- PRO TIP: Agua de sandia is one of the only aguas frescas that doesn’t require straining, making it one of the easiest to prepare. However, if you don’t plan on drinking it within one day, I do recommend straining it to prevent it from thickening.

A Note from Lola
HOW TO STORE AGUA FRESCA
Store agua fresca in an airtight container in the refrigerator for up to 2-3 days, ensuring it stays fresh and chilled. Ingredients tend to settle at the bottom, so remember to stir your agua fresca before serving.ON SWEETENERS
You can add as much or as little sugar as you’d like to all of your aguas frescas, including this one. I also like to use honey, agave, or simple syrup (boil equal parts water and sugar until sugar is dissolved) in my agua fresca recipes.ON TEXTURE
I have seen plenty of agua fresca recipes that say not to strain the ingredients. While I’m all about taking in all of the fiber and nutrients possible, agua fresca is meant to be light in texture – nowhere near a smoothie and not even as thick as a nectar. Therefore straining is essential in all of my recipes, except for my agua de sandía and agua de limón con sandía because watermelon is naturally watery and doesn’t require straining. However, if you don’t plan on drinking your watermelon agua fresca within one day, I do recommend straining it to prevent it from thickening.This recipe was originally published on July 15, 2015 and updated with step-by-step instructions and images on May 19, 2025.

Looks so refreshing! That cooking school is adorable. I wish my kitchen looked like that. I traveled to Morelia one time for a short weekend trip, and I remember eating corundas. They were so delicious!
The cooking school is amazing. It has an indoor and outdoor kitchen, a beautiful area for kids to play, hammocks to nap, and it’s all decorated by Cynthia and her father who imports artesanias from all over Mexico. Her restaurant also has a room dedicated to San Antonio where women come from all over the world to pray and ask for a novio! I need to go back just to take more pictures.:)
Once summer rolls around we eat watermelon like crazy and when I made this over the weekend everyone loved it!
My absolute favorite agua fresca. It is synonymous with summer!
