This Watermelon Juice recipe is the perfect way to cool off during the hot summer months. This drink can also be referred to as Watermelon Lime Aqua Fresca. Or in other words a fresh watermelon drink with a hint lime.

Use the leftover watermelon to make this Watermelon Feta Basil Salad. It’s light and refreshing, perfect for summer days. 

I live in Texas and let me tell ya, it gets HOT around here. To combat the heat and humidity I have made my fair share of refreshing drinks, ice cream, and popsicles.

A Summer Staple

Everyone knows you can’t experience a true summer without eating watermelon at least once throughout the scorching hot months. My family and I go to the beach on a regular basis in the summer. And every single time we go I always cut up a ripe watermelon to eat and enjoy while we’re there. If you prefer to eat the watermelon rather than drink it you can make these watermelon feta skewers.

  • Seedless watermelon- The riper the watermelon the sweeter the watermelon juice will be.
  • Water- This is optional. If you want a very concentrated watermelon taste in the drink you can omit the water.
  • Lime juice- The lime flavor isn’t too powerful, but just enough to catch your attention. If you want a stronger lime flavor consider adding some lime zest to the drink.
  • Sugar- Just in case you picked an un-ripe watermelon, the sugar will add some sweetness to the drink. However, you don’t have to add the sugar if you don’t want to.

How to Make Watermelon Juice

  1. To a blender add the watermelon cubes, lime juice, and water (if using).

  4. Stir in the sugar (can use honey or agave – to make it vegan). Chill the drink until cold.
  5. Serve over crushed ice with a garnish of fresh mint leaves.

Recipe Tips & FAQ

If you want a more pronounced lime flavor you can add fresh lime zest to the drink.

Instead of adding water you can add sparkling water, Gingerale, Sprite or 7-UP if you want a carbonated kick.

You can substitute honey or agave for the sugar. If you use agave you’ll have a vegan watermelon juice!

You may need to add more or less sugar depending on the sweetness of your watermelon.

How to Pick a Ripe Watermelon

Look for a field spot that is yellowish and creamy colored. The field spot is where the watermelon rested on the ground. If the field spot is more yellowish in color rather than white,  it means the watermelon was left on the vine to ripen longer. This means you’ll have a sweeter watermelon.

Look for web-like brown spots. The webbing (usually around the field spot) means there’s usually more sugar in the watermelon.

Pick a watermelon that’s heavy for its size.

Make sure the watermelon is firm.

Give the watermelon a tap with your knuckles. A ripe watermelon will have a deep hollow sound and an under-ripe or over-ripe melon will sound dull.
