Health Benefits
Watermelon contains lycopene, the antioxidant responsible for its red color, along with L-citrulline, an amino acid involved in nitric oxide production. Research continues to examine watermelon and L-citrulline for their potential role in supporting healthy circulation and vascular function. Learn more about watermelon and L-citrulline. Our Watermelon Basil Salad is another way to get in more melon into the rotation.
Watermelon and lime contribute vitamin C, an antioxidant that supports immune function, collagen production, and the absorption of iron from plant foods. The National Institutes of Health explains the functions of vitamin C.
Key Ingredients

- Watermelon: Watermelon supplies the natural sweetness, vibrant pink color, and most of the liquid in this recipe. Its soft, juicy flesh creates a smooth, light-bodied drink rather than a thick smoothie.
- Cucumbers: Two cucumbers add a clean, mild flavor that balances the sweetness of the watermelon. They make the juice taste lighter, crisper, and even more refreshing.
A full ingredient list with exact amounts is in the recipe card below.
Substitutions and Variations
- Fresh basil gives the juice a slightly peppery, aromatic flavor. Watermelon and basil are a surprisingly good team. They sound like an odd couple, but they make it work.
- Lemons can replace the limes for a different citrus flavor.
- Add a one-inch piece of peeled ginger through the juicer for a spicy, warming contrast to the cooling cucumber and mint.
- Replace some of the watermelon with fresh pineapple for a more tropical flavor. Pineapple will also make the juice tangier and slightly thicker.
How to Make Watermelon Cucumber Lime Juice

Step 1
Prepare the produce by removing and discarding the watermelon rind, chopping the cucumbers into large chunks, and peeling the limes.

Step 2
Run the produce through the juicer in batches. Feed some of the cucumber or watermelon through the juicer after the mint to help push it through the machine.

Step 3
After you're done juicing, stir the finished juice thoroughly to combine the flavors. Pour it into glasses and enjoy!
Expert Tips
- Chill the produce first. Refrigerating the watermelon and cucumbers before juicing gives you a colder drink without needing to add much ice.
- Use ripe watermelon. Since there is no added sweetener, the flavor of the finished juice depends heavily on the quality of the watermelon.
- Juice the mint between cucumber pieces. This helps move the lightweight leaves through the juicer rather than leaving them stuck inside.
- Stir before every serving. Fresh juice naturally separates as it sits. Separation is normal and does not mean the juice has spoiled.
- Drink it fresh. The flavor, aroma, and color are best immediately after juicing. If storing it, fill airtight jars close to the top to reduce air exposure.

Watermelon Cucumber Juice FAQs
It tastes mildly sweet, crisp, and refreshing. Watermelon supplies the sweetness, cucumber adds a clean vegetal note, lime provides tartness, and mint gives the drink a cooling herbal finish.
Yes. Add the watermelon, chopped cucumbers, peeled limes, and mint to a high-speed blender. Blend until completely smooth, working in batches if necessary. Pour the mixture through a fine-mesh strainer or nut-milk bag if you want a thinner juice. You can also leave it unstrained for more fiber and a texture closer to a smoothie.
Fresh watermelon cucumber juice is best enjoyed immediately or within 24 hours. You can generally refrigerate it in an airtight container for up to two days, but its flavor and freshness will gradually decline. Discard the juice if it develops an unpleasant fermented smell, excessive bubbling, or an unusual taste.

This Watermelon Cucumber Juice with lime and mint is sweet, cooling, citrusy, and wonderfully simple. With only four ingredients and no added sugar, it is an easy way to use fresh summer produce and make hydration a little more interesting.
