Why you need to try this recipe!
Watermelon Water is one of those recipes that feels effortless yet tastes fantastic. With just a few ingredients blended together and poured over ice, it’s an ideal drink for hot days, outdoor gatherings, or after exercise.
Because watermelon is high in water and contains electrolytes like potassium, this drink helps replenish fluids and supports hydration. The bright lime juice balances the sweetness and adds a fresh, tangy note.
Kids and adults alike enjoy this beverage. It’s customizable—omit or reduce sweetener, or swap sugar for agave if preferred.
Ingredients

To make watermelon water you only need a few ingredients: fresh watermelon, lime juice, a touch of sweetener if desired, and cold filtered water.
- Watermelon: Use seedless watermelon, cut into cubes. This recipe is a great way to use a less-flavorful melon and brighten it up.
- Sugar or sweetener: Optional. Omit for a lower-sugar option or substitute agave (use about half the amount) for a different sweetness profile.
- Limes: Fresh lime juice adds balance to the sweetness. Two small limes yield roughly 1/4 cup juice.
- Filtered water: Adds volume and makes the drink lighter and more refreshing.
How to Make Watermelon Water
This recipe comes together in a blender and takes only minutes. Follow these easy steps for the best results:

Step 1: Cube the watermelon. Use seedless watermelon and add the cubes to a large blender. If your blender is small, blend in batches.
Step 2: Add the water, sugar (or sweetener, if using), and lime juice.
Step 3: Blend until completely smooth. Straining is optional—leave the pulp for more body, or strain for a clearer beverage.
Step 4: Serve over ice and garnish with a lime wedge. Keep the drink very cold for best flavor.

You can prepare Watermelon Water ahead of time and refrigerate. Stir well before serving, since separation can occur as it sits.
