This watermelon limeade is made with just 4 ingredients – watermelon, mint, lime juice, and cucumber. An extra hydrating, juicy drink, it's one of our favourite summer drinks and a cinch to make. Naturally sweet and refreshing with no added sugar!

Pack this for a cute picnic with a vibrant rainbow salad or vegan chopped salad, or whip up some rainbow rolls and bring some hummus and crackers.

Ingredient Notes and Substitutions

  • Watermelon: a ripe melon will be the sweetest, and seedless is easier.
  • Lime juice: fresh is best, but juice from the fridge can be used in a pinch. You can mix lemon and lime too.
  • Mint: spearmint is a little sweeter than peppermint and still has a nice mint taste, but you can use either.
  • Cucumber: any type of cucumber will work, and no need to peel it.

Top Tips

  • Top with sparkling water: or try kombucha or ginger beer for a bit of a twist! I love the mix of watermelon and ginger beer.
  • Sweeten to taste: this is unsweetened, and depending on how sweet the melon is, you might find that it needs a little more. Add a touch of liquid sweetener if needed.
  • Use a less crisp melon: this is the perfect recipe for a melon that's ripe and sweet, but maybe not so crisp.

How to Store

Storage: keep your watermelon smoothie in the fridge for a day or two, covered.

Freezing: if you have some left over, make it into popsicles!

  1. What a refreshing drink! And your links are all so great! Aaand you brought back so many fun memories of summer when young! 🙂

    1. Awe, thank you so much, Rebecca! I'm delighted to hear you liked the post. I hope you're having a wonderful summer <3

  2. Oh Sophie this summery drink looks so good! Watermelon has always been my favorite summer fruit (and apricots too!) and I make every day watermelon gazpacho but this is such a great option when I'm craving for something more light and quick.
    Lovely pictures!


    PS: I still haven't had time to go to the beach even though I live like 5 minutes away from it, so I feel you! :-p

    1. Whoa! Watermelon gazpacho sounds amazing! So happy you like the post. Lol, I live like 5 minutes from the beach too! We got to get our toes wet at least once this summer. 🙂

  3. Oh this looks so refreshing and delicious! The only consolation for how fast summer flies by is the idea of fall flavors coming soon...:)

  4. YUM! This looks perfect for these warm summer days. Also, loving all these great links!


  5. Isn't is something how summer (and life) seems to last forever during the care free days of childhood. While we may not be fortunate enough to experience those days as adults. it's lovely to have those memories to look back on. This is an amazing summer refresher! I'd gladly sit on the back porch and sip one of these watermelon mint limeades. Cheers my friend!

    1. Seriously, where does the time go??? I'll never know. So happy you like the post, Jess. Wishing you a beautiful and long summer <3

  6. Beautiful photography! Looks so refreshing! Can't wait for local watermelon! Also, can we take a few months off of winter and add them to summer?

    1. Thank you so much, Melissa! And yes to local melon! I've missed the last few Kits markets and feel like I'm falling behind in the summer fruit game. I cannot wait to stock up again.

  7. I love that this is sugar-free! I'll need to try it out. Also, I feel exactly the same way about summer - It goes by way too fast!

  8. This post is so beautiful + the epitome of what I want to be glugging back in the warmer months.

    1. Awe, thank you so much Meredith! I wish I could share some porch hangs and big 'ol glasses of juice together. Stay cool, friend 🙂
