Watermelon water is so light, refreshing and satisfying! From Mexico, this recipe is for Agua de Sandia and is incredibly easy to make! All you need is watermelon, some water and a small amount of sugar, if desired.
My husband lived in southern Mexico for two years after high school. We met shortly after and he introduced me to all of his favorite foods and drinks. He loves "aguas frescas", which are very popular in Mexico. Agua de Sandia is near the top of his favorites list; he absolutely loves it.
This was inspired by my Watermelon Lemonade Slushie on this site, and pairs well with our Tart Lemon Cookies and our Chicken Caesar Wrap, which are both light and summery too.

How to Pick the Perfect Watermelon
My husband is really good at picking out watermelon! He follows these tips and gets a great one every time
- large ground spot - watermelons will have a yellow ground spot on them, that is usually rough in texture. The bigger the ground spot the better! It means it was allowed to ripen for a longer time before being picked, which will give it the best flavor.
- deep, hollow sound - when you knock on it, it should have a deep hollow sound. This will indicate it's juicy instead of airy (aka: grainy) and will have a great texture.
- bee stings - There should be plenty of bee stings- it'll look rough and scratched up, this means there were plenty of bees stinging it, indicating sweetness.
- character over beauty - a beautiful, green watermelon that is uniform in color might be beautiful and look tasty, but the flavor will likely be much less desirable than selecting a melon with more "character".

Ingredients

- lime or lemon juice - also optional, can be used in very small amounts to gently enhance the watermelon flavor.
See recipe card for quantities.
Instructions
1. Slice cold watermelon into cubes, around 2", but no need to be precise. The watermelon may also be cut at room temperature and then refrigerated.
2. Place half the watermelon in a blender and blend.
3. Add the other half of the watermelon and the water and a little sugar. Blend.
4. Add more sugar, to taste and lime juice, if desired. Serve cold.
Hint: Use cold water and cold watermelon for best results!
Substitutions
- No Water - this can easily be made without water. The less water you use, the less sugar is needed as the flavor is strong and sweet and undiluted.
- Sugar Free - make this sugar free by simply skipping the sugar. You can use an alternative sweetener if desired, but we often make it without any sweetener at all. It's a little lighter of a flavor, but we really enjoy it.
Variations
Giving the visitor ideas on how they can change this recipe to better suit their dinner guests, or their cultural cuisine, is a great way to increase the chances they make the recipe
- Spicy - top with a sprinkling of Tajin for that spicy Tajin fruit flavor! My husband does this sometimes and absolutely loves it.
- Deluxe - freeze cubes of watermelon and use them as ice cubes, then garnish with mint leaves or a lime wedge.
- Lemon Lime Soda - skip the sugar and replace the water with lemon-lime soda. To do this, we recommend pureeing the watermelon first, then gently stirring it into the soda so that the soda keeps its carbonation.
- Raspberry Watermelon Water - substitute 1 ½ cups of watermelon with 1 ½ cups fresh or frozen raspberries for an absolutely delicious variation.
- La Croix - puree the watermelon by itself, and add a little sugar if desired. Then mix slowly with your favorite La Croix or other seltzer water (we recommend a berry or lemon- lime for best results). Make sure to mix slowly to maintain that carbonation.
Equipment
- sharp knife - we love this long sharp knife for cutting a giant watermelon. Watermelons can be hard to cut due to their size, this knife would be a huge help.
- cutting board - an extra large cutting board is needed to comfortably cut a watermelon.
- high speed mixer - get a high speed mixer for best results. Our favorite is our ninja and we use it all the time for many different things.
Make Ahead
This recipe can be made ahead. We recommend waiting until the day of to blend, but you can chop your watermelon up to 2 days in advance and keep it refrigerated until ready to use.
Storage
Store in the refrigerator up to 3 days. Use a wooden spoon or spatula to give it a little stir before serving.
Use any leftovers to make watermelon popsicles!
Top tip
This drink is best served cold, add some ice if desired!
