What Is Watermelon Lemonade?
Watermelon lemonade is exactly what it sounds like: fresh watermelon blended with lemon juice and a little sweetener for a fruity take on classic lemonade. It's lighter and more refreshing than traditional lemonade, naturally sweet from the watermelon, and a pretty pink color.
This version adds raspberries for extra color and a hint of tartness, and swaps plain water for coconut water, which adds a natural sweetness and electrolytes.
Why You'll Love This Watermelon Lemonade
- Naturally sweetened. Ripe watermelon does most of the work. A small amount of honey or agave is optional and easy to leave out entirely if your watermelon is sweet enough.
- The coconut water difference. Using coconut water instead of plain water adds a subtle natural sweetness and electrolytes, making this as hydrating as it is delicious.
- The color. The watermelon and raspberries turn this lemonade a deep pink. It looks as good as it tastes.
- Ready in minutes. Blend, strain, stir, and chill. It couldn't be simpler.
- Crowd-friendly. Scales up easily for a crowd.

Ingredients for Watermelon Lemonade
- Watermelon — Use seedless watermelon. The riper and sweeter the watermelon, the better the lemonade.
- Fresh lemon juice — Please don't use bottled here. Fresh lemon juice makes a real difference. Roll them on the counter before squeezing to get the most juice out of each one.
- Raspberries — Fresh or frozen both work. They add a color and a hint of tartness that balances the sweetness of the watermelon.
- Coconut water — Adds natural sweetness and electrolytes. Use plain, unsweetened coconut water. Filtered water works as a substitute .
- Honey or agave (optional) — Taste the lemonade before adding any sweetener. A ripe watermelon may not need it at all. If you do add some, start with one or two tablespoons and adjust from there. For a no-sugar option, a few drops of stevia works well.
- Sea salt (optional) — Just a pinch per glass at serving. It enhances the flavor and adds a tiny electrolyte boost.
How to Make Watermelon Lemonade
Step 1: Blend the fruit
Add the watermelon cubes, raspberries, and lemon juice to a blender. Blend until completely smooth. You may need to do this in batches depending on the size of your blender.
Step 2: Strain
Pour the blended mixture through a fine mesh sieve into a large pitcher, pressing gently to extract all the liquid. Discard the solids. This step gives you a smooth, clear lemonade rather than a pulpy juice.
Step 3: Add the coconut water
Stir in the coconut water. Taste and add honey, agave, or a few drops of stevia if you'd like it a little sweeter. Stir well to combine.
Step 4: Chill and serve
Refrigerate for at least 30 minutes before serving, or pour directly over ice if you're in a hurry. Serve with a pinch of sea salt in each glass and garnish with a slice of watermelon, a few raspberries, or a lemon wedge.
Tips for the Best Raspberry Watermelon Lemonade
- Use cold ingredients. Starting with chilled watermelon and cold coconut water means you can pour this over ice right away without it tasting diluted.
- Start with ripe watermelon. The sweetness of the drink depends entirely on the fruit. A ripe, in-season watermelon needs little to no added sweetener.
- Taste before sweetening. Add the optional honey, agave, or stevia only after tasting. You might find you don't need it at all.
- Strain well. Taking the time to press the mixture through a fine mesh sieve gives you a cleaner, smoother drink.
- Make it ahead. This lemonade keeps in the fridge for up to 2 days. Give it a stir before serving.

Variations
- Sparkling watermelon lemonade. Swap the coconut water for sparkling water or club soda for a fizzy version. Add it just before serving so it doesn't go flat.
- Watermelon lemonade cocktail. Stir in a shot of vodka, gin, or white rum per glass. This also makes a great base for a pitcher cocktail.
- Mint watermelon lemonade. Add a handful of fresh mint leaves to the blender with the watermelon. Strain as usual.
- Extra berry. Add a handful of strawberries or blackberries to the blender along with the raspberries for a deeper berry flavor.
- Watermelon lemonade popsicles. Pour the finished lemonade into popsicle molds and freeze for a few hours. A great way to use up any leftovers.
What to Serve with Watermelon Lemonade
At a barbecue or pool party: This is the summer drink that works for everyone. Set out a big pitcher and let people help themselves.
Post-workout: The coconut water base makes this a hydrating option after exercise. Keep a jar in the fridge and pour over ice when you need it.
At brunch: Serve alongside a fruit spread or light salad.
As a mocktail: Pour over ice in a nice glass with a salted rim and a few raspberries for garnish. It looks festive enough to stand in for a cocktail at any gathering.
How to Store Watermelon Lemonade
Refrigerator: Store in a sealed pitcher or jar for up to 2 days. Give it a good stir before serving as the fruit solids can settle.
Freezer: Pour into ice cube trays and freeze. Use the cubes in future glasses of lemonade so it doesn't get diluted, or blend into a slushy.
This lemonade is best within the first day or two. Beyond that, the fresh fruit flavor starts to fade.
FAQ
- Can I make watermelon lemonade ahead of time?
Yes. It keeps well in the fridge for a couple days. Make it the morning of a gathering and it'll be ready to serve. - Do I need to add sweetener?
Not necessarily. Taste the lemonade after blending and straining, then add honey, agave, or a few drops of stevia to taste. - Can I skip the raspberries?
Absolutely. Without the raspberries you get a classic watermelon lemonade that's equally delicious. The raspberries add color and a hint of tartness but aren't essential to the recipe. - What can I use instead of coconut water?
Plain filtered water works fine as a substitute. You'll lose the natural sweetness and electrolyte benefit, but the lemonade will still taste great.
