There’s just something magical about watermelon in the summertime.

For me, summer officially starts the moment I blend up my first glass of homemade Agua de Sandía, or as we say in English, Watermelon Agua Fresca.

I remember the first time I made it—on a scorching July afternoon, desperate for something cold that wasn’t soda. I had a half-eaten watermelon in the fridge and no energy to cook. I tossed the chunks into my blender with a splash of lime and a drizzle of honey, and from the first sip, I was hooked.

Now, I’m sharing my go-to watermelon agua fresca recipe—it’s quick, aesthetic, super refreshing, and it’s one of my favorite nonalcoholic summer drinks that doubles as a gorgeous addition to any picnic or party spread. Ready to sip pretty?

What Is Agua de Sandía?

Agua de Sandía is a type of Agua Fresca, which literally translates to “fresh water” in Spanish. In Mexican culture, aguas frescas are light fruit-based beverages made by blending fruit, water, and sweetener. They're wildly popular as street drinks and often served in large jugs called vitroleros in markets or restaurants.

Unlike heavy juices or sugary sodas, aguas frescas are lightly sweet, hydrating, and taste like fruit-infused magic. And let’s be real—nothing says “chill summer mood” like a glass of ice-cold watermelon agua fresca.

What I love most is how flexible the recipe is. Whether you're sipping poolside, planning a mom-and-daughter brunch, or just trying to stay hydrated without resorting to plain water, this drink checks all the boxes: refreshing, easy, homemade, and totally aesthetic.

Why You’ll Love This Homemade Version

This homemade agua fresca tastes way better than anything you’ll find bottled in a store. You get to control the sweetness, skip the preservatives, and use real fruit. And guess what? It only takes about 5 minutes to make. Yep, five.

It’s also incredibly affordable. A single watermelon can make several servings of agua fresca, which means you’re saving money and staying refreshed all week long.

Plus, it’s such a crowd-pleaser! Whether you’re making it for a girls' night, Sunday brunch, or to impress your Instagram followers with something aesthetic, you’ll fall in love with this recipe like I did.

Ingredients (with Exact Measurements)

Here’s exactly what you’ll need for one full pitcher (about 4–6 servings):

Ingredients:

4 cups fresh seedless watermelon, cubed

1 ½ cups cold water (or coconut water for a tropical twist)

1 ½ tablespoons fresh lime juice (adjust to taste)

1 ½ tablespoons agave syrup or honey (adjust depending on how sweet your watermelon is)

Ice for serving

Optional garnishes: fresh mint leaves, lime slices, floral ice cubes, or cucumber ribbons

You can easily double or triple this recipe for larger gatherings. Want to make it extra chill? Use frozen watermelon cubes instead of ice.

Step-by-Step Instructions

This is one of the easiest recipes you’ll ever make—promise.

Step 1: Blend the Base

Add the 4 cups of cubed watermelon and 1 ½ cups of cold water into a blender. Blend until completely smooth, about 30–45 seconds.

Chef Tip: If your blender isn’t very powerful, blend the watermelon first, then add water to avoid splashes.

Step 2: Strain (Optional but Aesthetic)

Pour the mixture through a fine mesh strainer or cheesecloth into a large pitcher if you prefer a smoother texture. This step is optional, but it really elevates the look and feel—especially if you're serving it to guests.

Step 3: Flavor Boost

Add the lime juice and agave syrup, stirring well. Taste and adjust if needed—some watermelons are naturally sweeter than others.

Step 4: Chill & Serve

Fill glasses with ice, pour the agua fresca over, and garnish with fresh mint or lime slices. Sip and enjoy!

Make It Extra Aesthetic

Okay, so let’s talk aesthetics. You know, the Pinterest-worthy drink that makes you want to take a picture before every sip? That’s what we’re going for here.

Glassware Matters: Serve your agua fresca in mason jars, tall clear tumblers, or coupe glasses.

Garnishes Are Gold: Add a watermelon wedge, a sprig of mint, or a thin cucumber ribbon.

Floral Ice Cubes: Freeze edible flowers or mint leaves into ice cubes for a beautiful touch.

Pitcher Style: Pour it into a clear glass pitcher to show off that rosy hue.

This isn’t just a drink—it’s a vibe.
